Description
Technical Field
[0001] This utility model relates to the field of work technology, and in particular to a protective detection head for a steering wheel button function testing device. Background Technology
[0002] As the automotive manufacturing industry continues to move towards intelligent and high-end development, the complexity of automotive internal electronic systems is increasing day by day. As the core component of vehicle control, the reliability, durability, and safety of the steering wheel's button functions have become key factors related to driving experience and road safety. In order to meet the stringent quality control standards of the automotive industry, the importance of steering wheel button function testing devices is becoming increasingly prominent. Among them, the performance of the protective testing head directly affects the accuracy of the test results and the service life of the testing device.
[0003] The types of steering wheel buttons in cars are becoming increasingly diverse. In addition to traditional mechanical buttons, new types of buttons such as capacitive touch buttons and pressure-sensitive buttons are constantly emerging. These buttons are not only more complex in function, integrating functions such as multimedia control, driver assistance system adjustment, and intelligent voice interaction activation, but also place extremely high demands on the sensitivity, response speed, and stability of the buttons. Taking capacitive touch buttons as an example, they rely on human touch to change the capacitance value to trigger a signal. This requires the testing device's detection head to accurately simulate human touch actions and force, while ensuring that the accuracy of the test is not affected by external interference or wear during frequent testing. According to relevant industry research data...
[0004] Existing steering wheel button function testing devices mostly focus on the detection of button functions in their design, neglecting effective protection of the testing head itself. In actual testing, the testing head frequently comes into direct contact with the steering wheel buttons, and prolonged friction can easily lead to wear on the surface of the testing head, especially for buttons with special surface materials. Once the surface of the testing head is worn, its contact state with the button will change, which will affect the transmission and feedback of test signals and cause deviations in test results. At the same time, due to the close arrangement of steering wheel buttons, the testing head is very susceptible to accidental collisions with surrounding parts during the test, which increases maintenance costs and seriously affects the continuity of testing work. Utility Model Content

This solves the problem that the detection head frequently comes into direct contact with the steering wheel buttons, and prolonged friction can easily lead to wear on the surface of the detection head, especially for buttons with special surface materials. Once the surface of the detection head is worn, its contact state with the button will change, which will affect the transmission and feedback of the test signal and cause deviations in the test results. At the same time, during the test, due to the close arrangement of the steering wheel buttons, the detection head is very susceptible to accidental collisions with surrounding parts during movement, which increases maintenance costs and seriously affects the continuity of the test work.

[0031] Please see Figure 1-5 This utility model provides a technical solution: a protective detection head for a steering wheel button function testing device, including a steering wheel button function testing platform body 1, a placement platform 2, a drive assembly 3, a cylinder 4, a mounting plate 5, and a testing head 6;
[0032] The mounting plate 5 is equipped with protective components;
[0033] The protective assembly includes a transparent acrylic protective sleeve 8 and a protective plate 10. Two second T-shaped slots 14 are formed on the lower surface of the mounting plate 5. Two second T-shaped blocks 13 are fixedly installed on the upper surface of the support base of the transparent acrylic protective sleeve 8. The outer walls of the two second T-shaped blocks 13 are slidably connected to the interior of their corresponding second T-shaped slots 14. A second magnetic base 15 is fixedly installed on the lower surface of the mounting plate 5 near one end of the second T-shaped slot 14. A second magnetic block 12 is fixedly installed on the upper surface of the support base of the transparent acrylic protective sleeve 8. The second magnetic block 12 cooperates with the second magnetic base 15. The test head 6 is fixedly installed on the lower surface of the mounting plate 5. The lower surface of the transparent acrylic protective sleeve 8 is provided with a protective plate groove 7. The inner walls on both sides of the protective plate groove 7 are provided with first T-shaped block grooves 16. The test head 6 is located inside the transparent acrylic protective sleeve 8. The outer wall of the protective plate 10 is slidably connected to the inside of the protective plate groove 7. The outer walls on both sides of the protective plate 10 are fixedly installed with first T-shaped blocks 9. The outer walls of the two first T-shaped blocks 9 are respectively slidably connected to the inside of the corresponding first T-shaped block grooves 16. The lower surface of the transparent acrylic protective sleeve 8 is fixedly installed with a first magnetic seat 17. The lower outer wall of the protective plate 10 is fixedly installed with a first magnetic block 11. The first magnetic block 11 and the first magnetic seat 17 are used together.
[0034] The drive assembly 3 is fixedly installed inside the main body 1 of the steering wheel button function test bench. The upper surface of the mounting plate 5 is fixedly connected to the output end of the cylinder 4. The upper end connecting seat of the cylinder 4 is connected to the transverse guide rail on the drive assembly 3. The drive assembly 3 is composed of a longitudinal guide rail and a transverse guide rail. The placement platform 2 is fixedly installed on the guide rail inside the main body 1 of the steering wheel button function test bench.
[0035] Furthermore, when using this device, the protective plate 10 is initially in the closed state. The first magnetic block 11 and the first magnetic base 17 are attracted and engaged, and the protective plate 10 is fixed in the protective plate groove 7, shielding the test head 6 inside the transparent acrylic protective sleeve 8 to prevent damage to the test head 6 from external collisions, dust, etc. At the same time, the transparent acrylic protective sleeve 8 is slidably connected to the second T-shaped block groove 14 of the mounting plate 5 through the second T-shaped block 13, and attracted to the second magnetic base 15, firmly installed on the lower surface of the mounting plate 5, forming a surrounding protection for the test head 6, further protecting the test head 6. Then, when it is necessary to perform a steering wheel button function test, firstly through... The drive assembly 3 and cylinder 4 adjust the position of the mounting plate 5 and test head 6, aligning the test head 6 with a suitable position above the steering wheel buttons. During this process, the protective assembly is initially in a protective state. Then, external force is manually applied to make the protective plate 10 slide along the protective plate groove 7, the first T-block 9 slide along the first T-block groove 16, the first magnetic block 11 separates from the first magnetic seat 17, the protective plate 10 opens, exposing the test head 6, removing the obstruction to the test head 6, allowing the test head 6 to contact the steering wheel buttons for testing. The test head 6 contacts the steering wheel buttons to detect the button functions. After the test is completed, the drive assembly 3 and cylinder 4 adjust the test head 6 away from the steering wheel buttons, returning it to its initial position. Near the initial position, the protective plate 10 slides in the reverse direction, and the first T-block 9 slides in the reverse direction along the first T-block groove 16. The first magnetic block 11 and the first magnetic seat 17 are attracted and engaged again, the protective plate 10 closes, and the protective state is restored. At the same time, the transparent acrylic protective sleeve 8 is always stably installed on the mounting plate 5 through the cooperation of the second T-block 13 and the second T-block groove 14, and the second magnetic block 12 and the second magnetic seat 15, continuously protecting the test head 6. In this way, when the equipment is working, first place the steering wheel to be tested on the placement platform 2, and adjust the position of the mounting plate 5 and the test head 6 through the drive assembly 3 and the cylinder 4 so that the test head 6 is aligned with the steering wheel buttons. If the protective component is in the protected state, the protective plate 10 needs to be slid open to release the protection and expose the test head 6. The test head 6 contacts the button to perform functional testing. After the test is completed, the test head 6 is moved away from the button, the protective plate 10 is slid closed to restore the protected state, and the device is ready for the next test or storage. This protective test head not only enables the test head 6 to accurately test the steering wheel buttons, but also effectively protects the test head 6 in the non-test state, extending the service life of the test head 6 and ensuring the stability of the testing device and the accuracy of the test results. At the same time, the protective component is easy to install and operate, and is compatible with the workflow of steering wheel button function testing.
[0036] By effectively protecting the test head 6 in non-testing states through the protective component, the service life of the test head 6 is extended, ensuring the stability of the testing device and the accuracy of the test results. At the same time, the protective component is easy to install and operate, and is compatible with the workflow of steering wheel button function testing. This avoids the test head 6 from frequent direct contact with the steering wheel buttons, which can easily lead to wear on the surface of the test head due to long-term friction, thus effectively improving the service life of the test head 6.
[0037] Structural Description: Steering wheel button function test bench main body 1: Serves as the basic support and installation platform for the entire test device, providing installation space and support for drive components 3, placement platform 2, etc., ensuring the relative position stability of each component, and enabling the test device to carry out steering wheel button function testing in an orderly manner;

[0039] Drive component 3: Composed of longitudinal and transverse guide rails, it is fixedly installed inside the main body 1 of the steering wheel button function test bench, forming a two-dimensional motion guide system. Its transverse guide rail is used to connect the upper connecting seat of the cylinder 4, providing transverse and longitudinal motion tracks for the cylinder 4 and the subsequent connected mounting plate 5, test head 6, etc. Through the guiding effect of its own guide rail, the position of the test head 6 can be adjusted within a certain range to accurately align with the steering wheel buttons for testing.
[0040] Cylinder 4: The upper end connecting seat is connected to the horizontal guide rail on the drive assembly 3, and the lower surface output end is fixedly connected to the upper surface of the mounting plate 5. It plays the role of power transmission and position adjustment. It can slide along the horizontal guide rail of the drive assembly 3 to achieve horizontal position adjustment. It can extend and retract to change the vertical height of the mounting plate 5 and the test head 6, so as to meet the needs of the test head 6 to move closer to or further away from the steering wheel buttons and provide power support for the test action.
[0041] Mounting plate 5: The upper surface is fixedly connected to the output end of cylinder 4, and the lower surface is used to install test head 6 and protective components. It is the mounting base for test head 6 and protective components. Two second T-shaped block slots 14 are opened on the lower surface for connecting with the second T-shaped block 13 on the transparent acrylic protective sleeve 8. A second magnetic seat 15 is fixedly installed on the lower surface near the second T-shaped block slot 14 and cooperates with the second magnetic block 12 on the transparent acrylic protective sleeve 8 to realize the installation and fixation of the transparent acrylic protective sleeve 8 in the protective component. The test head 6 is fixedly installed on the lower surface as a component for directly testing the function of steering wheel buttons.
[0042] Test head 6: Fixedly installed on the lower surface of the mounting plate 5, located inside the transparent acrylic protective sleeve 8, used to contact the steering wheel buttons and test the button functions. It is the core execution component for realizing the steering wheel button function test.
[0043] Transparent acrylic protective sleeve 8: As one of the main protective structures of the protective component, two second T-shaped blocks 13 and a second magnetic block 12 are fixedly installed on the upper surface of the upper support base. A protective plate groove 7 is opened on the lower surface, and a first magnetic seat 17 is fixedly installed on the lower surface. The second T-shaped blocks 13 cooperate with the second T-shaped block groove 14 of the mounting plate 5 to realize the initial connection and positioning of the transparent acrylic protective sleeve 8 and the mounting plate 5.

The first T-shaped blocks 9 are fixedly installed on both outer walls, and the first magnetic block 11 is fixedly installed on the lower outer wall. The first T-shaped blocks 9 cooperate with the first T-shaped block grooves 16 on both sides of the protective plate groove 7 to ensure the stability and accuracy of the protective plate 10 sliding in the protective plate groove 7 and prevent it from deviating during sliding. The first magnetic block 11 cooperates with the first magnetic seat 17 on the lower surface of the transparent acrylic protective sleeve 8 to realize the locking (protection state) or unlocking (open state) of the protective plate 10, control whether the test head 6 is exposed, and play the role of protecting the test head 6.
[0045] Protective plate slide groove 7: Formed on the lower surface of the transparent acrylic protective sleeve 8, it provides a sliding track and accommodating space for the protective plate 10, allowing the protective plate 10 to slide within it. This enables the switching between the protective state (protective plate 10 closed, blocking the test head 6) and the open state (protective plate 10 slides open, exposing the test head 6) of the protective component. At the same time, the first T-shaped block grooves 16 on both sides of it serve to guide and limit the protective plate 10.
[0046] First T-block 9: Fixedly installed on both outer walls of the protective plate 10, and slidably connected to the first T-block groove 16 on both inner walls of the protective plate slide groove 7, to guide the sliding of the protective plate 10 in the protective plate slide groove 7, to ensure the stability of the sliding trajectory of the protective plate 10, to make the protective components move accurately, and to reliably realize the switching of the protective function.
[0047] First magnetic block 11: Fixedly installed on the lower outer wall of the protective plate 10, and used in conjunction with the first magnetic seat 17 on the lower surface of the transparent acrylic protective sleeve 8. When the protective plate 10 slides to the closed position (blocking the test head 6), the first magnetic block 11 and the first magnetic seat 17 are attracted and engaged, fixing the position of the protective plate 10 and putting the protective component in a protective state. When it is necessary to open the protective plate 10, an external force is applied to separate the first magnetic block 11 from the first magnetic seat 17, and the protective plate 10 can slide open along the protective plate slide groove 7.
[0048] First magnetic base 17: Fixedly installed on the lower surface of transparent acrylic protective sleeve 8, and cooperates with the first magnetic block 11 on the protective plate 10. The protective plate 10 is locked by magnetic attraction. It is the key structure for the protective component to maintain the protective state, ensuring that the protective plate 10 can stably cover the test head 6 in the non-test state, and protect the test head 6 from external collisions, dust and other influences.
[0049] The second T-block 13 is fixedly installed on the upper surface of the support base of the transparent acrylic protective sleeve 8. There are two of them. The outer wall of the second T-block is slidably connected to the inside of the second T-block groove 14 on the lower surface of the mounting plate 5. It serves to connect the transparent acrylic protective sleeve 8 and the mounting plate 5. During installation, the second T-block 13 slides into the second T-block groove 14 to achieve initial connection and positioning, ensuring the accuracy and stability of the installation of the protective components.
[0050] The second magnetic block 12 is fixedly installed on the upper surface of the support base of the transparent acrylic protective sleeve 8 and works in conjunction with the second magnetic seat 15 on the lower surface of the mounting plate 5. After the transparent acrylic protective sleeve 8 is initially connected to the second T-shaped block groove 14 through the second T-shaped block 13, the second magnetic block 12 and the second magnetic seat 15 are attracted to each other, further fixing the position of the transparent acrylic protective sleeve 8, enhancing the stability of the connection between the protective component and the mounting plate 5, and preventing the transparent acrylic protective sleeve 8 from loosening during equipment operation or testing.
