Description

Technical Field

[0001] This utility model relates to the field of automotive testing technology, and in particular to a pressure and temperature sensor mounting base. Background Technology

[0002] In the early stages of automotive R&D and design, during the testing and verification phase, sensors are needed to monitor and collect the operating temperature and pressure parameters of various components in real time.

[0003] Currently, temperature and pressure sensors are individually welded to the test sample using their own dedicated mounting bases. This method not only causes significant damage to the test sample but also results in low installation efficiency. More importantly, after testing, the sensor mounting base is permanently left on the test sample and cannot be reused. Furthermore, a new mounting base needs to be fabricated for each new test, which increases the complexity of installation and disassembly and significantly raises the operating cost. Summary of the Invention

[0004] To address the aforementioned technical problems, this utility model provides a pressure and temperature sensor mounting base. To provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. This summary is not intended as a general commentary, nor is it intended to identify key / important components or to describe the scope of protection of these embodiments. Its sole purpose is to present some concepts in a simple form as a prelude to the detailed description that follows.

[0005] The present invention adopts the following technical solution:

[0006] A pressure and temperature sensor mounting base is provided, comprising: a base body, wherein the base body is T-shaped to form a temperature sensor mounting post, a pressure sensor mounting post, and a test piece docking post;

[0007] The end faces of the temperature sensor mounting post and the pressure sensor mounting post are provided with threaded grooves that match the sensor threads.

The interior of the base body is provided with a sampling channel that communicates with the threaded grooves and the medium inlet.

[0008] Furthermore, the pressure and temperature sensor mounting base further includes a nut, which is welded to the test piece, and the thread of the nut matches the external thread formed on the outer surface of the test piece's mating column.

[0009] Furthermore, a clearance groove is formed on the outer surface of the mating column seat of the test piece, and the bottom of the clearance groove is provided with an external thread for threaded connection with the test piece; the length of the clearance groove is greater than the width of the nut.

[0010] Furthermore, the temperature sensor mounting post and the test piece docking post are located on opposite sides of the pressure sensor mounting post.

[0011] Furthermore, the end face of the temperature sensor mounting post is provided with a temperature sensor mounting thread groove that matches the thread of the temperature sensor, and the end face of the pressure sensor mounting post is provided with a pressure sensor mounting thread groove that matches the thread of the pressure sensor.

[0017] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the drawings used in the description of the embodiments or the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0018] Figure 1 This is a schematic diagram of the structure of a pressure and temperature sensor mounting base according to this utility model. Detailed Implementation

[0019] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings. It should be understood that the described embodiments are merely some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0020] like Figure 1 As shown, in some illustrative embodiments, a pressure and temperature sensor mounting base is provided, which can simultaneously support a pressure sensor and a temperature sensor and dock with the measured object. Specifically, it includes a base body 100 and a nut 500. The base body 100 has a T-shaped structure. The T-shaped structure design divides the base body into three columnar structures, namely a temperature sensor mounting column 200, a pressure sensor mounting column 300, and a measured object docking column 400.

[0021] During testing, the temperature sensor is mounted on the temperature sensor mounting post 200, the pressure sensor is mounted on the pressure sensor mounting post 300, and the test piece docking post 400 is used to connect the base body 100 and the test piece.

[0022] The temperature sensor mounting post 200 and the measured component docking post 400 are located on opposite sides of the pressure sensor mounting post 300. The temperature sensor mounting post 200 is one branch of the T-shaped structure used to mount the temperature sensor. The pressure sensor mounting post 300 is the middle vertical section of the T-shaped structure, perpendicular to the temperature sensor mounting post 200, used to mount and fix the pressure sensor. The measured component docking post 400 is the other branch of the T-shaped structure, opposite the temperature sensor mounting post 200, used to achieve the installation and fixation between the base body 100 and the measured component.

[0023] The structural design and layout of the three pillars make the sensor mounting base structure of this embodiment more rational. This ensures that after the sensors are installed and connected to the device under test, the entire testing system maintains a compact structure, with no interference between the sensors. Furthermore, the T-shaped structure design not only allows for optimal arrangement of the pillars, thus optimizing functionality—that is, enabling the simultaneous installation and docking of temperature and pressure sensors with the device under test within a limited space, saving installation space—but also provides sufficient support and stability.

[0024] The base body 100 is made of Q235, which is a carbon structural steel with good plasticity and toughness, suitable for withstanding impact and vibration. It also has good weldability and is not prone to cracking. As a common carbon steel, it has low cost and excellent processing performance.

[0025] Both the temperature sensor mounting post 200 and the pressure sensor mounting post 300 have threaded grooves on their end faces that match the sensor threads. Specifically, the end face of the temperature sensor mounting post 200 has a temperature sensor mounting threaded groove 210 that matches the temperature sensor threads, meaning the internal thread of the temperature sensor mounting threaded groove 210 perfectly matches the thread type and size of the temperature sensor, ensuring that the temperature sensor can be smoothly screwed in and tightened. Similarly, the end face of the pressure sensor mounting post 300 has a pressure sensor mounting threaded groove 310 that matches the pressure sensor threads, meaning the internal thread of the pressure sensor mounting threaded groove 310 matches the thread type and size of the pressure sensor, ensuring that the pressure sensor can be accurately installed onto the pressure sensor mounting post 300.

[0026] The inner diameter and thread type of the temperature sensor mounting groove 210 and the pressure sensor mounting groove 310 can be reasonably customized according to the size of the sensor to adapt to sensors of different specifications, thereby improving the versatility and applicability of the sensor mounting base in this embodiment and meeting diverse testing needs.

[0027] The outer surface of the test piece docking post 400 is provided with an external thread 410 for threaded connection with the test piece. When the test piece has a screw hole that can be directly connected to the sensor mounting base of this embodiment, the base and the test piece can be quickly and easily installed by directly threading the external thread 410 of the test piece docking post to the screw hole on the test piece. This direct threaded connection method simplifies the installation steps, improves installation efficiency, and is suitable for situations where the test piece has a pre-drilled standard screw hole.

[0028] Nut 500 is welded to the test piece (DPT), and the thread of nut 500 matches the external thread 410 on the outer surface of the DPT's mating post. When the DPT cannot be threadedly connected to the sensor mounting base of this embodiment, for example, if the DPT does not have a pre-drilled thread hole or the thread hole specifications do not match, an alternative connection method can be used: nut 500 is welded to a designated position on the DPT, and the reliable connection between the base and the DPT is achieved by utilizing the fit between nut 500 and the external thread 410 of the DPT's mating post. After testing, only nut 500 needs to be replaced. Although this connection method is slightly more complex than a direct threaded connection, it still ensures the strength and reliability of the connection. It is suitable for situations where the DPT does not have a pre-drilled thread hole or requires a special connection, allowing the main body to be reused, with high versatility, strong substitutability, and low operating costs.

[0029] In addition, when the device under test can be directly threaded to the sensor mounting base of this embodiment, the nut 500 can also play a reverse locking role, ensuring that the base does not loosen when encountering a sudden impact, thereby improving the reliability and safety of the connection.

[0030] A clearance groove 420 is formed on the outer surface of the test piece mating post 400. The bottom of the clearance groove 420 is provided with an external thread 410 for threaded connection with the test piece. The length of the clearance groove 420 is greater than the width of the nut 500 so as to provide sufficient space to realize the reverse locking effect of the nut 500 and ensure that the nut 500 can be installed smoothly and mate with the external thread 410 of the test piece mating post.

[0031] When the nut 500 is threaded onto the mating post 400 of the workpiece under test and reaches the inner end of the relief groove 420, that is, when the inner end face of the nut 500 is in contact with the inner end of the relief groove 420, the distance between the outer end face of the nut 500 and the end face of the mating post 400 of the workpiece under test is at least 10mm. This distance design provides sufficient space to ensure that the nut 500 can effectively prevent the sensor mounting base from loosening under sudden impact or vibration when performing the reverse locking function, and also ensures that the nut 500 can generate sufficient preload when locking, thus enhancing the stability of the connection.

[0032] The end face of the test piece docking column 400 has a medium inlet 430. The base body 100 has a sampling channel 600 that is connected to the temperature sensor mounting threaded groove 210, the pressure sensor mounting threaded groove 310 and the medium inlet 430. That is, the temperature sensor mounting threaded groove 210 and the pressure sensor mounting threaded groove 310 are connected to the sampling channel 600 as medium outlets, thus forming a path for medium flow.

[0033] The above structural design allows the pressure sensor and temperature sensor to share the sampling channel 600. By sharing the sampling channel 600, the number of channels inside the base is reduced, making the overall structure simpler. Since it is not necessary to set up a separate sampling channel for each sensor, the space utilization rate can be improved, making the base design more compact.

[0034] The inner diameter of the sampling channel 600 is greater than or equal to 8mm. This size design can effectively improve the stability and reliability of the sampling process.

[0035] The external thread 410 on the outer surface of the test piece's mating post is a straight thread with a nominal diameter of at least 12 mm. Straight threads offer advantages such as simple machining, convenient mating, and good sealing performance, making them particularly suitable for testing scenarios requiring frequent mating and disassembly. The minimum nominal diameter of 12 mm provides a larger thread contact area, thereby enhancing the mechanical strength and stability of the mating.

[0036] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
