Description

Technical Field

[0001] This utility model relates to the field of power detection technology, and in particular to a power energy storage detection device. Background Technology

[0002] Energy storage testing devices primarily rely on multimeters for testing through physical contact. Specifically, the multimeter's test leads need to make contact with the electrical component contacts of the energy storage device to obtain accurate test data.

[0003] However, in practice, this contact method has certain problems, especially when there is dust or other contaminants on the surface of the power component contacts. The presence of dust and other impurities can increase the contact resistance between the detection pad and the power component contacts, leading to poor contact, which significantly reduces the detection effect and affects the accuracy of the measurement. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a power storage detection device that solves the technical problem that dust between the detection plate and the contact end can easily lead to poor contact.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a power storage detection device, comprising:

[0006] A linear drive source, with a detection plate axially arranged at its telescopic end;

[0007] The top sealing plate is fixed to the telescopic end and forms a dynamic sealing reference surface;

[0008] An elastic deformable container, the top of which is sealed and fixed to the bottom of the top sealing plate and forms a columnar cavity, the detection piece is suspended at the top of the columnar cavity and remains in a non-contact state with the inner wall of the elastic deformable container;

[0009] Vent holes: Multiple vent holes are arranged in a ring on the upper part of the side wall of the elastic deformable container, and the axial position of each vent hole changes continuously with the compression of the elastic deformable container.

[0010] Once the bottom of the elastic deformable container forms a contact seal with the top of the power element, the drive source continues to advance, causing axial compression deformation of the elastic deformable container, resulting in:

[0011] The nonlinear reduction in volume of the cylindrical cavity forces the internal gas to be ejected from the high-level exhaust port;

[0012] As the compression process progresses, the exhaust port moves downward, creating a diffused airflow whose spatial position changes continuously.

[0013] The airflow creates a turbulent field on the surface of the contact point between the detection plate and the power component, and the adhering material is peeled off through the gas-solid coupling effect.

[0014] Preferably, the sidewall thickness of the elastic deformable container is gradient-distributed, with the wall thickness in the upper region being greater than that in the lower region, forming a structure with increasing compressive resistance.

[0015] Preferably, the bottom of the elastic deformable container is integrally formed with an annular sealing lip, which undergoes radial expansion deformation during compression to form an adaptive sealing connection with the top of the power component.

[0016] Preferably, the sidewall of the elastic deformable container is provided with axially arranged annular folds, and the vent is opened at the crest of the fold. When the elastic deformable container is compressed and contracted, the cross-sectional shape of the vent gradually changes from a circle to an ellipse.

[0017] By employing the above technical solution, this utility model provides a power storage detection device, which has at least the following beneficial effects:

[0018] This invention generates a gas-solid coupling effect by compressing an elastic deformable container, thereby inducing shear stress and forming a boundary layer separation effect. This causes particulate matter to detach from the contact surface between the test piece and the power component, ensuring that impedance measurement is performed in a dust-free environment when the test piece moves down and contacts the power component. This effectively avoids poor contact caused by particulate matter, thus ensuring the accuracy of the test results. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0025] Please refer to Figures 1-3 This embodiment proposes a power storage detection device, including:

[0026] Linear drive source 1, with a detection plate 11 axially arranged at its telescopic end;

[0027] Top sealing plate 2 is fixed to the telescopic end and forms a dynamic sealing reference surface;

[0028] The elastic deformable container 3 has a gradient distribution of sidewall thickness, with the upper region having a thicker wall than the lower region, forming a structure with increasing compression resistance. Its top is sealed and fixed to the bottom of the top sealing plate 2, forming a columnar cavity. The detection piece 11 is suspended at the top of the columnar cavity and remains in non-contact with the inner wall of the elastic deformable container 3. The bottom of the elastic deformable container 3 is integrally formed with an annular sealing lip 32, which undergoes radial expansion deformation during compression, forming an adaptive sealing connection with the top of the power component.

[0029] Vent holes 31 are provided in a ring on the upper part of the side wall of the elastic deformable container 3. The axial position of each vent hole 31 changes continuously with the compression of the elastic deformable container 3. The side wall of the elastic deformable container 3 is provided with an axially arranged annular folded part. The vent holes 31 are provided at the crest of the folded part. When the elastic deformable container 3 is compressed and contracted, the cross-sectional shape of the vent holes 31 gradually changes from a circle to an ellipse.

[0030] After the bottom of the elastic deformable container 3 forms a contact seal with the top of the power element, the linear drive source 1 continues to advance, causing the elastic deformable container 3 to undergo axial compression deformation, resulting in:

[0031] The nonlinear reduction in volume of the cylindrical cavity forces the internal gas to be ejected from the high-level exhaust port 31;

[0032] As the compression process progresses, the exhaust port 31 moves downward, forming a diffused airflow whose spatial position changes continuously;

[0033] The airflow forms a turbulent field on the surface of the contact point between the detection plate 11 and the power component, and the adhering material is stripped off through the gas-solid coupling effect.

[0034] like Figures 2-3As shown, when the power component is delivered to the testing station, the telescopic end of the linear drive source 1 drives the bottom of the elastic deformable container 3 to first contact the top of the component, forming an initial cylindrical cavity through elastic deformation of the material. The initial thrust of the linear drive source 1 causes a slight compression of the elastic deformable container 3. At this time, elastic potential energy is stored in the wall of the elastic deformable container 3, which is used to generate mechanical energy for subsequent airflow.

[0035] As the linear drive source 1 continues to advance, the gradient wall thickness design of the elastic deformable container 3 leads to a nonlinear increase in its compressive resistance. The rapid reduction of the cylindrical cavity volume causes a sudden increase in internal air pressure. The high-position exhaust port 31, being located at the pressure antinode, forms a preferential airflow channel. The downward movement of the exhaust port 31 generates a Doppler effect. The scattered airflow forms a von Kármán vortex street below the detection plate 11. The gradually flattening deformation of the exhaust port 31 causes periodic pulsations in the airflow. The shear stress generated by the gas-solid coupling effect forms a boundary layer separation effect, causing particles to detach from the contact surface between the detection plate 11 and the power component. When the detection plate 11 moves down to contact the power component contact, impedance measurement is performed in a dust-free environment to prevent particulate matter from causing poor contact and affecting the detection effect.

[0036] When the linear drive source 1 retracts, the elastic deformable container 3 rises synchronously with the telescopic end and completely detaches from the power element, gradually recovering in mid-air to avoid reattaching the particles to the contact surface between the detection plate 11 and the power element.

[0037] like Figure 2 As shown, a pressure sensor 4 is also provided between the detection plate 11 and the telescopic end of the linear drive source 1. When the detection plate 11 contacts the contact surface of the power component, the pressure sensor 4 monitors the contact pressure between the two in real time, thereby effectively preventing detection errors caused by poor contact and ensuring the accuracy of the detection results.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
