Description

Technical Field

[0001] This utility model relates to the field of automotive parts testing technology, and in particular to an automotive pressure sensor testing module. Background Technology

[0002] In the field of automotive manufacturing and quality inspection, automotive pressure sensors play a crucial role. They are responsible for monitoring pressure parameters in various automotive systems, such as the fuel system, braking system, and air conditioning system. Their performance directly affects the safety, reliability, and overall operating efficiency of the vehicle. Therefore, accurate and efficient testing of automotive pressure sensors is particularly important. The emergence of an automotive pressure sensor testing module aims to meet the needs for comprehensive and accurate testing of pressure sensors during automotive production, maintenance, and R&D processes, providing strong support for ensuring high-quality production and stable operation of automobiles.

[0003] Existing automotive pressure sensor testing technologies often employ relatively simple and singular mechanical structures for sensor fixation. For example, some testing equipment uses integrated fixing clamps, the shape and size of which are designed for specific sensor models. These clamps fix the sensor in the testing position by tightening screws or locking clips. The principle is to use external mechanical force to firmly fix the sensor and prevent displacement during testing. Some testing platforms use magnetic fixation methods, relying on magnetic force to attract the sensor. However, this method has certain requirements for the sensor material, and the strength of the magnetic force is difficult to control precisely. During testing, these fixation methods can only meet the fixation needs of specific types of sensors. They are unsuitable for sensors of different brands and models due to differences in their dimensions, interface shapes, etc.

[0004] However, existing technologies struggle to effectively clamp different types of sensors. The automotive industry produces a wide variety of sensors, with pressure sensors from different manufacturers varying significantly in shape, size, and connection methods. Existing clamping or magnetic methods are too limiting and cannot be flexibly adjusted to accommodate this diverse range of sensors. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an automotive pressure sensor testing module, which aims to improve the problem that existing technologies have difficulty in effectively clamping different types of sensors.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automotive pressure sensor testing module, comprising a testing platform, one end of an air pipe fixedly connected to the inner wall of the testing platform, a cylinder fixedly connected to the other end of the air pipe, a pressing module fixedly connected to the output end of the cylinder, wires fixedly connected to the upper surface of the pressing module, a display screen fixedly connected to the outer wall of the testing platform, a clamping assembly provided on the upper surface of the testing platform, and a quick-release assembly provided on the upper surface of the testing platform; The clamping assembly includes a clamping seat, which is disposed on the upper surface of the test platform. A fixing block is fixedly connected to the outer wall of the clamping seat. One end of a spring is fixedly connected to the outer wall of the fixing block. A clamping module is fixedly connected to the other end of the spring. A limit block is fixedly connected to the outer wall of the clamping module. A limit ring is fixedly connected to the upper surface of the clamping seat.

[0007] Furthermore, the quick-release assembly includes a fixing base, which is disposed on the upper surface of the test platform. A rotating shaft is rotatably connected to the inner wall of the fixing base, and a locking block is fixedly connected to the outer wall of the rotating shaft. A rotating roller is disposed on the inner wall of the locking block, and a handle is fixedly connected to the outer wall of the rotating roller.

[0008] Furthermore, the outer wall of the rotating roller is rotatably connected to the inner wall of the fixed seat, and the lower surface of the clamping block is attached to the outer wall of the clamping seat.

[0009] Furthermore, the card block has a slot inside and is located below the handle.

[0010] Furthermore, the clamping seat has a sliding groove inside, and the outer wall of the clamping module is slidably connected to the inner wall of the clamping seat.

[0011] Furthermore, the spring is disposed between the fixing block and the clamping module, and the clamping module is capable of sliding on the inner wall of the clamping seat.

[0012] Furthermore, the outer wall of the clamping seat is attached to the outer wall of the fixing seat, and the locking block is positioned above the test platform.

[0013] Furthermore, the cylinder is installed on the inner wall of the test platform, and the movement trajectory of the pressing module runs through the test platform.

[0014] This utility model has the following beneficial effects: 1. In this utility model, when using the automotive pressure sensor test module, the sensor is placed in the clamping seat, the fixing block is fixed in the clamping seat, and the two ends of the spring are respectively connected to the fixing block and the clamping module. The spring applies pressure to make the clamping module slide along the guide in the clamping seat to clamp the sensor. The limiting block and the limiting ring cooperate to restrict movement, flexibly adjust the clamping range, solve the problem of poor compatibility, improve versatility, and adapt to diverse testing needs.

[0015] 2. In this utility model, when the clamping seat needs to be replaced, the handle is turned and rotated on the fixed seat via the rotating roller, which drives the locking block to be lifted. The locking block rotates on the fixed seat via the rotating shaft, and its internal slot allows the handle to pass through, quickly releasing the clamping seat and realizing quick disassembly. This solves the problem of cumbersome and time-consuming traditional replacement operations, improves the efficiency of maintenance and replacement of parts, saves costs, and improves overall work efficiency.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Reference Figure 1 - Figure 3 An embodiment of this utility model is provided: an automotive pressure sensor test module, including a test platform 1, one end of an air pipe 5 is fixedly connected to the inner wall of the test platform 1, the other end of the air pipe 5 is fixedly connected to a cylinder 6, the output end of the cylinder 6 is fixedly connected to a pressing module 3, the upper surface of the pressing module 3 is fixedly connected to an electric wire 7, the outer wall of the test platform 1 is fixedly connected to a display screen 2, the upper surface of the test platform 1 is provided with a clamping component, and the upper surface of the test platform 1 is provided with a quick-release component; The clamping assembly includes a clamping seat 4, which is used to hold the automotive pressure sensor to be tested, allowing multiple components to achieve a movement effect. The clamping seat 4 is set on the upper surface of the test platform 1. A fixing block 9 is fixedly connected to the outer wall of the clamping seat 4. The fixing block 9 is fixed to the clamping seat 4, providing a fixing point for the spring 12, ensuring that the spring 12 can stably apply pressure to the clamping module 10. One end of the spring 12 is fixedly connected to the outer wall of the fixing block 9. The spring 12 applies pressure to the clamping module 10 through its own elastic deformation, enabling the clamping module 10 to... The spring 12 is used to clamp the sensor. The other end of the spring 12 is fixedly connected to the clamping module 10. Under the pressure of the spring 12, the clamping module 10 slides in the clamping seat 4 to realize the actual clamping action of the sensor. The outer wall of the clamping module 10 is fixedly connected to the limiting block 11. The limiting block 11 is fixed on the clamping module 10 and cooperates with the limiting ring 8 to limit the movement range of the clamping module 10. The upper surface of the clamping seat 4 is fixedly connected to the limiting ring 8. The limiting ring 8 and the limiting block 11 interact to limit the movement of the clamping module 10.

[0020] Specifically, when using the automotive pressure sensor test module, the sensor is first placed in the clamping seat 4, and the fixing block 9 is firmly fixed on the clamping seat 4. One end of the spring 12 is connected to the fixing block 9, and the other end of the spring 12 is connected to the clamping module 10, so that the spring 12 can apply pressure to the clamping module 10, causing it to slide along the guide structure within the clamping seat 4, thereby reliably clamping the sensor. At the same time, the limiting block 11 fixed on the clamping module 10 cooperates with the limiting ring 8 to restrict the movement of the clamping module 10, thereby achieving effective clamping of different types of sensors. This process solves the problem of poor compatibility of traditional test modules with different types of sensors, achieving the effect of improving the versatility of the test module and adapting to diverse sensor testing needs.

[0021] Reference Figure 1 - Figure 5The quick-release assembly includes a fixed base 13, which is mounted on the upper surface of the test platform 1. A rotating shaft 14 is rotatably connected to the inner wall of the fixed base 13. The rotating shaft 14 fixes a locking block 15 and allows it to rotate on the fixed base 13, providing rotational support for the movement of the locking block 15. The locking block 15 is fixedly connected to the outer wall of the rotating shaft 14. The locking block 15, by lifting and lowering, fixes and releases the clamping seat 4. A slot is provided on the inner wall for the screw handle 17 to pass through. A rotating roller 16 is provided on the inner wall of the locking block 15. The rotating roller 16 connects the screw handle 17 and the fixed base 13, allowing the rotation of the screw handle 17 to be achieved on the fixed base 13. The screw handle 17 is fixedly connected to the outer wall of the rotating roller 16. The screw handle 17 transmits operating force by rotating. The subsequent structural action is driven to lift the locking block 15, thereby releasing the fixation of the clamping seat 4. The outer wall of the rotating roller 16 is rotatably connected to the inner wall of the fixed seat 13. The lower surface of the locking block 15 is attached to the outer wall of the clamping seat 4. The locking block 15 has a slot inside and is located below the handle 17. The clamping seat 4 has a sliding groove inside. The outer wall of the clamping module 10 is slidably connected to the inner wall of the clamping seat 4. The spring 12 is located between the fixed block 9 and the clamping module 10, and the clamping module 10 can slide on the inner wall of the clamping seat 4. The outer wall of the clamping seat 4 is attached to the outer wall of the fixed seat 13. The locking block 15 is located above the test platform 1. The cylinder 6 is located on the inner wall of the test platform 1. The movement trajectory of the pressing module 3 runs through the test platform 1.

[0022] Specifically, when it is necessary to replace the clamping seat 4, first turn the handle 17. The handle 17 rotates on the fixed seat 13 through the rotating roller 16, which drives the locking block 15 to be lifted. The locking block 15 rotates on the fixed seat 13 through the rotating shaft 14. Its internal slot allows the handle 17 to pass through, so that the clamping seat 4 can be quickly released and disassembled. This operation solves the problem of cumbersome and time-consuming operation of replacing the clamping seat 4 in traditional test modules, and achieves the purpose of improving the efficiency of test module maintenance and component replacement, greatly saving time and labor costs, and improving overall work efficiency.

[0023] Working principle: When using the automotive pressure sensor test module, the sensor is placed in the clamping seat 4. The fixing block 9 fixes one end of the spring 12 to the clamping seat 4, and the other end of the spring 12 is fixed to the clamping module 10, thereby applying pressure to the clamping module 10. The clamping module 10 slides within the clamping seat 4 to clamp the sensor. The limiting block 11 is fixed to the clamping module 10 to limit the movement of the ring 8 on the clamping module 10, thereby enabling the clamping of different types of sensors. In addition, when the clamping seat 4 needs to be replaced, first turn the handle 17. The handle 17 rotates on the fixed seat 13 via the rotating roller 16. Then lift the locking block 15. The locking block 15 is fixed and rotated on the fixed seat 13 via the rotating shaft 14. The locking block 15 has a slot for the handle 17 to pass through, thereby releasing the clamping seat 4 and achieving quick disassembly of the clamping seat 4.
