Description

Technical Field

[0001] This utility model relates to the field of automotive instrument testing technology, specifically to an automotive instrument electric vibration testing device. Background Technology

[0002] Electrical vibration testing of automotive instruments is a key test for evaluating their reliability, durability, and functional stability under vibration conditions simulating vehicle operation.

[0003] Specifically, it is to test the mechanical performance of the instrument, detect whether the mechanical structure of the instrument is loose, detached or damaged in a vibration environment, assess whether the instrument can still display data, receive input signals and output correct information normally in a vibration environment, and identify potential design or manufacturing defects (such as cracked welds, poor circuit contact, inaccurate sensors, etc.).

[0004] In traditional experimental setups, the installation method and position of instruments on the fixed fixture can affect the test results. Incorrect installation, such as uneven tightening torque of the mounting bolts, may cause additional stress and deformation of the instrument during vibration, affecting its normal performance. Inaccurate installation position may cause the vibration environment that the instrument is subjected to to be inconsistent with the actual usage conditions.

[0038] Please see Figure 1-6 In traditional experimental setups, the installation method and position of instruments on the fixed fixture can affect the test results. Incorrect installation, such as uneven tightening torque of the mounting bolts, may cause additional stress and deformation of the instrument during vibration, affecting its normal performance; while inaccurate installation position may cause the vibration environment that the instrument is subjected to to be inconsistent with the actual use conditions.

[0039] Furthermore, if the test sequence is unreasonable, the instrument may be damaged in the early test, thus affecting the accuracy of the subsequent test; and if the test direction is not set accurately, it may not be able to fully simulate the vibration direction that the instrument is subjected to in actual use. Based on this, this application provides an electric vibration test device for automotive instruments, including a support frame 1 for support, a monitoring component 2 is arranged above the support frame 1, a vibration plate 6 is arranged at the bottom of the monitoring component 2, a mounting plate 3 is arranged on the top of the vibration plate 6, and an instrument panel 4 for testing is arranged at the mounting plate 3.

[0040] The support frame 1 includes a support plate 11, and fixed frames 13 are provided on both sides of the top of the support plate 11. A monitoring component 2 is installed in the middle of the fixed frame 13 for monitoring the instrument panel 4.

[0041] The top of the support plate 11 is provided with a protrusion 14, the top of the protrusion 14 is adapted to the vibratory plate 6, and is used to support the vibratory plate 6.

[0042] Mounting plate 3 includes a vertical plate 31 and a base plate 33. The vertical plate 31 is located in the middle of one side of the horizontal plate 21 and is used to cooperate with the instrument panel 4 for installation and testing.

[0043] The support plate 11 is made of metal (such as stainless steel) and has good rigidity and stability, and can withstand various forces generated during the test.

[0044] The mounting bracket 13 is installed on both sides of the top of the support plate 11, and is generally welded from profiles such as channel steel or angle steel. It has a dedicated mounting structure in the middle for fixing the monitoring component 2, ensuring that the monitoring component 2 can accurately monitor the instrument panel 4 and will not shake or shift due to vibration during the test. To enhance the stability of the mounting bracket 13, reinforcing ribs can be added at its connection with the support plate 11.

[0045] The protrusion 14 is disposed on the top of the support plate 11, and is usually integrally formed with the support plate 11 or fixed by welding. The top shape of the protrusion 14 is adapted to the bottom shape of the vibratory feeder 6, and is generally a flat surface or a curved surface with a certain curvature to achieve a good support effect. The number and distribution of the protrusions 14 are reasonably designed according to the size and weight of the vibratory feeder 6 to ensure that the weight of the vibratory feeder 6 can be evenly borne and the vibration can be transmitted to the support plate 11.

[0046] Monitoring component 2 is installed in the middle of the mounting frame 13 and consists of multiple sensors and a data acquisition system. The sensors include accelerometers, displacement sensors, and temperature sensors, which can monitor various parameters of the instrument panel 4 in real time during vibration. The accelerometer is used to measure the acceleration of the vibrating plate 6 to ensure that the vibration environment meets the test requirements;

[0047] The displacement sensor can detect the displacement change of the instrument panel 4 during vibration and determine whether it has become loose or deformed.

[0048] The temperature sensor is used to monitor the temperature change of the instrument panel 4 during the test to prevent overheating from affecting its performance. The data acquisition system processes and analyzes the data collected by the sensor in real time and transmits the results to the computer terminal for operators to observe and record.

[0049] The vibratory feeder 6 is located at the bottom of the monitoring component 2 and is the core component that generates vibration. An electric vibrator is installed inside the vibratory feeder 6; by controlling the frequency and amplitude of the electric vibrator, different vibration environments can be simulated.

[0050] The vertical plate 31 is located in the middle of one side of the horizontal plate 21, and is generally made of lightweight, high-strength materials such as aluminum alloy. Multiple mounting holes 54 are provided on the surface of the vertical plate 31 for mounting the instrument panel 4. The position and size of the mounting holes 54 are precisely designed according to the model and specifications of the instrument panel 4 to ensure that the instrument panel 4 can be accurately mounted on the vertical plate 31 and is securely installed.

[0051] The base plate 33 is vertically connected to the vertical plate 31. Its function is to further fix the instrument panel 4 and transmit vibration to the instrument panel 4. The bottom of the base plate 33 is tightly fitted to the top of the vibrating plate 6 and connected by bolts or other fixing methods to ensure that vibration can be effectively transmitted to the instrument panel 4.

[0052] During the test, the instrument panel 4 is first mounted on the vertical plate 31 through the mounting holes 54, ensuring a secure and accurate installation. Then, the mounting plate 3 is connected to the vibratory feeder 6, and the electric vibrator is turned on. The vibration frequency and amplitude are set according to the test requirements. The monitoring component 2 begins real-time monitoring of various parameters of the instrument panel 4 and transmits the data to a computer terminal. During the test, the operator can observe the performance changes of the instrument panel 4 through the computer terminal, such as whether it can display data normally and whether there is any loosening of the mechanical structure. After the test, the monitoring data is analyzed and evaluated to determine whether the instrument panel 4 meets the quality requirements.

[0053] The support frame 1 ensures that the components do not shake or shift during the test, thus guaranteeing the accuracy of the test results. The monitoring component 2 is equipped with a variety of sensors that can monitor various parameters of the instrument panel 4 in real time and comprehensively during the vibration process, such as acceleration, displacement and temperature, providing reliable data support for accurately evaluating the performance of the instrument panel 4.

[0054] The vibratory plate 6 can precisely control the frequency and amplitude of vibration through an electric vibrator, which can simulate various vibration environments that a car may encounter during actual driving, making the test results more realistic and reliable.

[0055] The vertical plate 31 and the base plate 33 of the mounting plate 3 are reasonably designed, which can facilitate the installation of instrument panels 4 of different models and specifications, and the installation position is accurate, ensuring that the instrument panel 4 can accurately withstand vibration, thereby improving the efficiency and accuracy of the test.

[0056] The front of the vertical plate 31 has two symmetrically arranged sliding grooves 32, which are adapted to the rear flange of the instrument panel 4.

[0057] The top of the base plate 33 is provided with two symmetrically arranged adjustment rails 35, which are adapted to the bottom flange of the instrument panel 4.

[0058] The top of the vertical plate 31 has a through hole, and an adjusting rod 34 is installed at the through hole. The adjusting rod 34 is inserted into the inside of the slide groove 32 and is used to adjust the vertical position of the instrument panel 4.

[0059] A reinforcing strip 16 is provided in the middle of the fixed frame 13. The reinforcing strip 16 is adapted to the monitoring component 2. The monitoring component 2 includes a horizontal plate 21. A display 22 is installed on the horizontal plate 21. The display 22 is connected to the interface on one side of the instrument panel 4 through a cable for transmitting signals and monitoring experimental results.

[0060] The top two sides of the support plate 11 are provided with adjustment grooves 12, and sliders 15 are slidably connected to the adjustment grooves 12. The sliders 15 are adapted to the bottom of the fixing frame 13.

[0061] The vertical plate 31 features two symmetrical rectangular sliding grooves 32 on its front side. In practice, when technicians install the instrument panel 4 onto the vertical plate 31, they simply align the flange on the back of the instrument panel 4 with the sliding groove 32 and gently push the instrument panel 4; the flange will then smoothly slide along the sliding groove 32. This design makes the instrument panel 4 more stable during installation, preventing shaking or misalignment caused by improper installation. For example, when installing a large automotive instrument panel 4, the precise guidance of the sliding groove 32 allows operators to easily and accurately install the instrument panel 4 into place, greatly improving installation efficiency.

[0062] One end of the adjusting rod 34 passes through the through hole and inserts into the inner side of the slide groove 32. By rotating the adjusting rod 34, the vertical position of the instrument panel 4 can be precisely adjusted. The adjusting rod 34 is equipped with scale markings. In actual operation, the operator can adjust the instrument panel 4 to a suitable height by rotating the adjusting rod 34 and observing the scale markings according to the test requirements. For example, when conducting tests under different vibration conditions, it may be necessary to adjust the height of the instrument panel 4 to simulate different installation positions. This operation can be easily achieved by using the adjusting rod 34.

[0063] The reinforcing strip 16 in the middle of the mounting bracket 13 is made of channel steel, and its shape and size are adapted to the horizontal plate 21 of the monitoring component 2. The reinforcing strip 16 is tightly connected to the mounting bracket 13 by bolts, providing additional support and stability for the monitoring component 2. The display 22 is fixed to the horizontal plate 21 by screws, and the cable is a shielded cable, which effectively reduces signal interference and ensures the accuracy and stability of data transmission. During the test, the display 22 displays various parameters of the instrument panel 4 in real time, such as speed, rotation speed, and temperature. Technicians can observe the data on the display 22 to understand the working status of the instrument panel 4 in a timely manner.

[0064] The adjustment grooves 12 on both sides of the top of the support plate 11 match the slider 15. The slider 15 is connected to the bottom of the fixing frame 13 by bolts and can slide freely in the adjustment groove 12.

[0065] In practical use, if it is necessary to adjust the position of the fixed frame 13, simply loosen the bolts between the slider 15 and the fixed frame 13, push the fixed frame 13 so that the slider 15 slides into the adjustment groove 12 to the appropriate position, and then tighten the bolts. This allows the position of the fixed frame 13 to be flexibly adjusted according to the test requirements, improving the versatility and adaptability of the test device.

[0066] The sliding groove 32 of the vertical plate 31 and the adjusting rail 35 of the base plate 33 are adapted to the flange of the instrument panel 4, which can ensure that the instrument panel 4 is accurately aligned during installation, reduce test errors caused by installation deviations, and improve the reliability of test results.

[0067] The adjusting rod 34 at the top of the vertical plate 31 and the adjusting groove 12 on the support plate 11 enable flexible adjustment of the vertical position of the instrument panel 4 and the horizontal position of the fixing frame 13, respectively. This allows the test device to adapt to instrument panels 4 of different sizes and models, as well as different test requirements, improving the versatility and applicability of the device.

[0068] The reinforcing strip 16 in the middle of the fixing frame 13 provides additional support for the monitoring component 2, enhancing the structural stability of the entire test device. During vibration testing, it effectively reduces component swaying and displacement caused by vibration, ensuring the accuracy of monitoring data.

[0069] Using shielded cables to connect the display 22 and the instrument panel 4 effectively reduces signal interference, ensuring the stability and accuracy of data transmission. This also ensures that the installation and adjustment of the entire testing setup are simple and convenient, requiring no complex tools or skills from the operators. This significantly improves testing efficiency and reduces labor costs.

[0070] The mounting plate 3 and the vibratory feeder 6 are connected by a base 5. The base 5 includes a seat 51, a positioning plate 52 is provided at the bottom of the seat 51, one or more mounting holes 54 are arranged in a circular array at the top of the positioning plate 52, and a positioning hole 53 is provided in the middle of the positioning plate 52. The positioning hole 53 is adapted to the vibratory feeder 6.

[0071] The vibratory plate 6 includes a plate body 63, a circular plate 64 is provided on the top of the plate body 63, the circular plate 64 is adapted to the positioning plate 52, and screws 66 are arranged in a ring array on the top of the circular plate 64, the screws 66 are adapted to the mounting holes 54.

[0072] The positioning plate 52 is fixed to the bottom of the base 51, and a positioning hole 53 is provided in the middle of the positioning plate 52 to ensure precise fit with the vibratory plate 6.

[0073] The disc body 63 is equipped with a vibration generating device such as an electric vibrator. The circular plate 64 is located on the top of the disc body 63 and cooperates with the positioning disc 52. The diameter of the circular plate 64 is the same as that of the positioning disc 52. The top of the circular plate 64 is arranged in a ring array with multiple screws 66, such as six, which correspond one-to-one with the mounting holes 54 on the positioning disc 52.

[0074] Installation process

[0075] When installing the base 5 and the vibratory feeder 6, first align the vibratory feeder 6 with the mounting hole 54 on the positioning plate 52 via the screw 66 on its circular plate 64. Slowly lower the vibratory feeder 6 so that the screw 66 is inserted into the mounting hole 54. Then tighten the screw 66 with the nut to ensure a tight connection between the vibratory feeder 6 and the base 5. During the installation process, the positioning hole 53 plays a role in precise guidance and positioning, ensuring that the installation position of the vibratory feeder 6 is accurate.

[0076] The positioning hole 53 in the middle of the positioning plate 52 is adapted to the vibratory plate 6, and the screw 66 on the circular plate 64 corresponds one-to-one with the mounting hole 54 on the positioning plate 52, so that the vibratory plate 6 can be accurately installed on the base 5, ensuring the installation accuracy of the test device and reducing the test error caused by installation deviation.

[0077] By engaging the screw 66 with the mounting hole 54 and tightening it with a nut, a secure connection is formed between the vibratory feeder 6 and the base 5. During vibration testing, this effectively prevents the vibratory feeder 6 from shaking or shifting, ensuring the stability and reliability of the test.

[0078] A positioning protrusion 65 is provided in the middle of the circular plate 64. The positioning protrusion 65 is adapted to the positioning hole 53 and is used to fix the base 5 with the screw 66 and the mounting hole 54.

[0079] The bottom of the disc body 63 is provided with a fixing seat 61, and the bottom of the fixing seat 61 is provided with a support foot 62, which is adapted to the protrusion 14 on the support plate 11.

[0080] The positioning protrusion 65 in the middle of the circular plate 64 is cylindrical. When installing the vibratory feeder 6, the positioning protrusion 65 can be inserted into the positioning hole 53, playing a good positioning and guiding role. For example, when the operator hoists the vibratory feeder 6 above the base 5, the position of the vibratory feeder 6 can be quickly and initially determined by the cooperation between the positioning protrusion 65 and the positioning hole 53, so that the screw 66 on the circular plate 64 can be accurately aligned with the mounting hole 54 on the positioning plate 52, greatly improving the installation efficiency.

[0081] The screws 66 arranged in a ring array on the top of the circular plate 64 are used by operators to tighten nuts onto the screws 66 using a wrench during installation, ensuring a tight fit between the circular plate 64 and the positioning plate 52. Tightening the nuts requires following a specific sequence and torque to ensure even force distribution on each screw 66 and guarantee the stability of the connection.

[0082] The mounting base 61 at the bottom of the disc 63 has internal reinforcing ribs to enhance its load-bearing capacity. The function of the mounting base 61 is to evenly transfer the weight of the disc 63 to the support feet 62, while providing a stable mounting foundation for the support feet 62.

[0083] The matching of the positioning protrusion 65 in the middle of the circular plate 64 with the positioning hole 53 provides accurate positioning for the installation of the vibratory plate 6, enabling the screw 66 to quickly and accurately align with the mounting hole 54, improving installation efficiency and accuracy, and ensuring the installation quality of the test device.

[0084] The tight fit between the screw 66 and the mounting hole 54, along with the tightening effect of the nut, ensures a secure connection between the vibratory feeder 6 and the base 5. This effectively prevents loosening or displacement between the vibratory feeder 6 and the base 5 during vibration testing, guaranteeing the stability and reliability of the test.

[0085] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art.
