[0002] In the automobile parts manufacturing industry, there are many buttons on the automobile central control panel, and many buttons are fixed by gluing and other methods during assembly. If the button cap falls off the button body during use, it may cause serious functional failure. Therefore, a device capable of testing the button top pullout force is urgently needed to exclude products that do not meet the top pullout force requirements in actual production. SUMMARY

[0003] The utility model aims to provide a kind of top pullout force testing device of automobile central control panel, which can solve at least one of the above problems.

[0004] According to one aspect of the utility model, a kind of top pullout force testing device of automobile central control panel is provided, including upper pressing plate, bottom plate, support plate, top rod, spring and pressure sensor, support plate is equipped with bottom plate, upper pressing plate is located above support plate, the bottom end of spring is in bottom plate, one end of top rod is in abutment with the top end of spring, the other end is stretched out after penetrating support plate, pressure sensor is located at the contact of spring and top rod.

[0005] The utility model has the beneficial effects that: by being equipped with top rod, it can be in abutment with the button on the automobile central control panel, and the pressure value under a certain stroke can be preset by the compression amount of spring. Therefore, when the upper pressing plate is pressed downward, the corresponding force on the button acts on the top rod, causing the top rod to press down and push the spring to be compressed. The spring reacts on the top rod, and the top pullout force received by the button can be tested by the pressure sensor. The product with substandard top pullout force can be quickly excluded, ensuring the reliability and safety of the automobile central control panel during use.

[0006] In some embodiments, the top rod is multiple, the spring corresponds to multiple top rods, and the pressure sensor corresponds to multiple springs. In this way, multiple buttons can be tested for top pullout force at the same time, greatly improving the detection efficiency.

[0007] In some embodiments, the top pullout force testing device of automobile central control panel further includes an adjusting bolt, the bottom of the bottom plate is provided with a threaded hole, the adjusting bolt cooperates with the threaded hole, and the bottom end of the spring is in abutment with the adjusting bolt. In this way, the compression degree of the spring can be adjusted by the adjusting bolt, thereby facilitating the adjustment of the rebound force of the spring and meeting the requirements of different buttons for top pullout force testing.

[0008] In some implementations, the upper surface of the base plate is provided with multiple cable outlet slots, each corresponding to a pressure sensor. This facilitates the wiring of the wires connected to the pressure sensors and improves neatness.

[0009] In some implementations, the support plate is equipped with positioning blocks. This facilitates the positioning of the automotive center console panel to be tested, enabling rapid product positioning and preventing the product from being installed backwards.

[0010] In some implementations, the support plate has a mounting groove, and the positioning block is located within the mounting groove. This mounting groove facilitates quick and easy installation of the product. Attached Figure Description

[0016] The present invention will now be described in further detail with reference to the accompanying drawings.

[0017] Reference Figures 1-5 A device for testing the detachment force of a car center console panel includes an upper pressure plate 1, a base plate 2, a support plate 3, a push rod 4, a spring 5, and a pressure sensor 6. The support plate 3 is mounted on the base plate 2, and the upper pressure plate 1 is located above the support plate 3. The bottom end of the spring 5 is located inside the base plate 2. One end of the push rod 4 abuts against the top end of the spring 5, and the other end extends through the support plate 3. The pressure sensor 6 is located at the contact point between the spring 5 and the push rod 4. The pressure sensor 6 can be connected to an external controller, which has a display screen. The controller converts the pressure signal into a digital signal, allowing for intuitive acquisition of the pressure value. This allows for quick determination of whether the corresponding button meets the required detachment force.

[0018] During use, the support plate 3 is fixed on the bottom plate 2. The automotive center console panel to be tested is placed on the support plate 3, and the button is aligned with the ejector rod 4, such that the ejector rod 4 abuts against the lower side of the button. After the product is placed, the upper pressing plate 1 presses down to clamp the product. At this time, under the downward pressure of the upper pressing plate 1, the button presses down and transmits the acting force to the ejector rod 4. At this time, the ejector rod 4 compresses the spring 5 downward, and the rebounding force of the spring 5 acts on the button, causing the spring 5 to bear the corresponding upward ejection force, and the pressure sensor 6 outputs the measured pressure signal. When the button meets the corresponding ejection force requirement, it is a good product; when the button loosens under the corresponding ejection force, the pressure value detected by the pressure sensor does not meet the requirement, and it is a defective product.

[0019] There are multiple ejector rods 4, and there are multiple corresponding springs 5 and multiple corresponding pressure sensors 6 for the springs 5. Therefore, during detection, the ejector rods 4 can correspond to multiple buttons, and multiple buttons can be detected at one time, greatly improving the detection efficiency.

[0020] The ejection force testing device for the automotive center console panel of the present utility model further includes an adjusting bolt 7. A threaded hole 21 is provided at the bottom of the bottom plate 2, and the adjusting bolt 7 is engaged with the threaded hole 21. The bottom end of the spring 5 abuts against the adjusting bolt 7. Therefore, during actual use, the compression degree of the spring 5 can be adjusted by the adjusting bolt 7.

[0021] When performing an ejection force test on the buttons of the automotive center console panel, according to the ejection force requirements of each button, the compression degree of each corresponding spring 5 is adjusted in advance, so that when the ejector rod 4 presses down the spring 5 during the test, the button receives a corresponding rebounding force and an upward ejection force acts on the button. When the ejection force of the button meets the requirement, the button is qualified; when the ejection force of the button does not meet the requirement, the button is prone to loosening and other phenomena when receiving the corresponding ejection force, and the button is unqualified.

[0022] A plurality of wire outlet grooves 22 are provided on the upper end surface of the bottom plate 2, and the wire outlet grooves 22 are provided corresponding to the pressure sensors 6 one by one. By providing the wire outlet grooves 22, the wires connected to the pressure sensors 6 can be routed along the wire outlet grooves 22, avoiding messy wiring.

[0023] A positioning block 31 is fixed on the support plate 3 by screws. Through the positioning block 31, it is convenient to cooperate with the corresponding hole positions of the product, avoiding misplacement when the product is placed on the support plate 3.

[0024] An installation groove 32 is provided on the support plate 3, and the positioning block 31 is located in the installation groove 32. By providing the installation groove 32, it is convenient to limit and install the center console panel, preventing the product from shifting during the test.

[0025] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of this utility model, and these all fall within the protection scope of this utility model.
