Description

Technical Field

[0001] The present invention relates to the technical field of testing equipment, and specifically, to a bracket and a testing method for the collision test of a triboelectric nanogenerator. Background Art

[0002] TENG refers to a triboelectric nanogenerator, which is mainly composed of electrodes and positive and negative triboelectric materials. Through the coupling of the triboelectrification effect and electrostatic induction, it can effectively convert the mechanical energy generated by the friction of an object into electrical energy. When two triboelectric materials come into contact with each other, frictional charges are generated. The triboelectric material with stronger electron-attracting ability has a negative charge on its surface, while the material that loses electrons has a positive charge on its surface. When the two triboelectric materials are separated from each other, opposite charges form an electric field between the two triboelectric materials, thereby forming a potential difference between the electrodes on the back of the two materials, driving electrons to flow from one electrode to the other through an external circuit, and generating electrical energy output.

[0003] Common triboelectric nanogenerators are mainly divided into the following four working modes: vertical contact-separation mode, horizontal sliding mode, single-electrode mode, and independent layer mode. The TENG in the vertical contact-separation mode is the most common triboelectric power generation structure. In this structure, two different triboelectric materials (usually two polymers) are stacked face to face, and sheet metal electrodes are pasted on the back of the polymer materials. At the same time, under the condition of no external pressure, there is a certain gap between the two triboelectric materials. When the two materials come into contact with each other, opposite surface charges are formed on the two contact surfaces. After the external force is removed, the two triboelectric materials are separated from each other, an electric field is formed between the two triboelectric materials, a potential difference is formed between the electrodes, driving the flow of electrons, and generating electrical energy output.

[0004] The collision test of a triboelectric nanogenerator is an important link to evaluate its performance and reliability in a mechanical shock or vibration environment. In the collision test, most linear motors use traditional fixed brackets, which usually have a preset fixed height and distance and do not allow users to adjust according to different test requirements. The main limitation of this kind of bracket is the lack of flexibility and the inability to adapt to a changing test environment or motors of different specifications. In the prior art, such as the Chinese utility model document with the authorization announcement number CN221947952U, which discloses a motor bracket. By setting an installation groove for fixedly installing a capacitor in the bracket, the installation of the capacitor is made more convenient and fast, and at the same time, the resonance between the motor and the capacitor is reduced, improving the stability of the motor. Although the above scheme has the above advantages, the disadvantage is that the device in the above scheme cannot adjust the horizontal or vertical position of the motor according to the actual use requirements, and the practicability of the device is relatively low.

[0005] Some more advanced bracket systems include adjustable functions that allow users to adjust the height or distance of the motor within a certain range, such as screw lifting. Although providing a certain degree of flexibility, the adjustment process of these systems is often cumbersome and not precise enough. High-end bracket systems may include automated adjustment functions that adjust the position of the motor through electronic control (such as the patent with application publication number CN118566723A). These systems offer higher precision and repeatability, but their widespread application is limited due to their complexity and high cost. Summary of the Invention

[0037] At present, most linear motors use traditional fixed brackets and cannot be adjusted according to different test requirements. For this reason, an embodiment of the present invention provides a bracket for the collision test of a triboelectric nanogenerator, referring to Figures 1 - 3, the bracket includes a substrate 2, a pair of linear motor supports 3, a moving block 1, a pair of side supports 8, an electric energy collection mechanism, a rear bracket 7 after collision, and a sensor moving block 6, where: the substrate 2 is horizontally fixed on the tabletop; the pair of linear motor supports 3 are vertically located on both sides of one end of the substrate 2, one end of the linear motor support 3 is fixed on the tabletop, and each linear motor support 3 includes two symmetrically arranged motor support plates; the moving block 1 is arranged on the linear motor support 3 and is detachably connected between the two symmetrically arranged motor support plates, the moving block 1 can move vertically along the linear motor support 3, and the linear motor is arranged on the moving block 1; the pair of side supports 8 are vertically located on both sides of the substrate 2, the side supports 8 are close to the other end of the substrate 2, the side supports 8 are detachably connected to the tabletop, and the side supports 8 can move horizontally; the electric energy collection mechanism is located between the pair of side supports 8, both sides of the electric energy collection mechanism are detachably connected to the pair of side supports 8 respectively, and can move vertically along the side supports 8; the other end (front end) of the linear motor is connected to the electric energy collection mechanism, and the side support 8 drives the linear motor to move through horizontal movement; the rear bracket 7 after collision is fixed to the other end of the substrate 2 by bolts, the rear bracket 7 after collision is perpendicular to the side support 8, the rear bracket 7 after collision is detachably connected above the tabletop at the other end of the substrate 2, and the rear bracket 7 after collision can move horizontally; the sensor moving block 6 is arranged on the side of the rear bracket 7 after collision close to the substrate 2, a triboelectric nanogenerator is arranged on the sensor moving block 6, the triboelectric nanogenerator is divided into two parts, one part (a piece of polar material of the triboelectric nanogenerator) is fixed on the sensor moving block 6, and the other part (the other piece of polar material) moves with the movement of the linear motor; the sensor moving block 6 is detachably connected to the rear bracket 7 after collision, and the sensor moving block 6 can move vertically along the rear bracket 7 after collision.

[0038] In the embodiment of the present invention, the installation heights of the moving block 1 and the electric energy collection mechanism are determined according to the vertical positions of the linear motor and the triboelectric nanogenerator required for the test, and the installation positions of the side supports 8 and the rear bracket 7 after collision are determined according to the horizontal positions of the linear motor and the triboelectric nanogenerator required for the test. After determining the horizontal and vertical positions of the linear motor and the triboelectric nanogenerator according to the test requirements, fix the linear motor supports 3, the side supports 8, and the rear bracket 7 after collision on the tabletop, and then install the linear motor and the triboelectric nanogenerator to start the collision test.

[0039] In some embodiments, both the substrate 2 and the motor support plate are fixed to the desktop by bolts to ensure the overall stability of the bracket. On the side of the motor support plate in contact with the moving block 1, a plurality of first connection holes are evenly spaced in the vertical direction. On the side of the moving block 1, there are moving block mounting holes matching the first connection holes. A first fastener passes through the moving block mounting hole and the first connection hole to fix the moving block 1 at a preset height. By fixing the two moving blocks 1 to the linear motor support 3 respectively through the first fasteners, and by setting a plurality of first connection holes in the vertical direction, the moving block 1 can be fixed at different heights, realizing the vertical movement of the moving block 1 on the surface of the linear motor support 3, so as to adapt to various test requirements with high flexibility. When adjusting the position of the moving block 1, it is necessary to first remove the first fastener, move the moving block 1 to the target position and then fix it again.

[0040] In the above embodiments of the present invention, the connection structure between the moving block 1 and the linear motor support 3 is particularly suitable for situations where the height or position needs to be frequently adjusted, and can flexibly adapt to different collision test requirements. The uniform distribution of the first connection holes ensures the precise positioning of the moving block 1 at the preset height, which is beneficial to improving the accuracy of position adjustment. The smaller the distance between adjacent first connection holes, the higher the height adjustment accuracy of the moving block 1, which can be comprehensively determined according to factors such as collision test requirements and processing capabilities.

[0041] As an example, the first fastener is a screw. The moving block 1 is fixed to the linear motor support 3 by screws. The screw connection is firm and can provide sufficient fastening force to ensure the stability of the moving block 1 in the fixed state. The above detachable connection method of the moving block 1 is convenient for assembly and maintenance. The moving block 1 can be flexibly adjusted between the two motor support plates to adapt to different test requirements, enhancing the flexibility and versatility of the bracket.

[0042] In some embodiments, the side of the motor support plate has an L-shaped surface, and both ends of the moving block 1 have L-shaped ends matching the L-shaped surface. The matching design of the L-shaped surface and the L-shaped ends increases the contact area and improves the stability of the overall structure.

[0043] In some embodiments, a plurality of second connection holes are evenly spaced along the length direction of the substrate above the desktop. On the side support 8, there are side support mounting holes matching the second connection holes. A second fastener passes through the side support mounting hole and the second connection hole to fix the side support 8 at a preset position. By setting a plurality of second connection holes in the length direction of the substrate 2, the side support 8 can be fixed at different horizontal positions, realizing the horizontal movement of the side support 8.

[0044] As an example, the second fastener is a screw. After removing the screw, the movement of the side support 8 can be realized, which is convenient for adjusting its position according to test requirements, and the installation and disassembly are simple and convenient, and the maintenance is easy.

[0045] In some embodiments, the side support 8 is a triangular bracket, which has the advantages of strong stability, high structural strength, and simple installation, can ensure the stability of the electric energy collection mechanism, and thus improve the test accuracy.

[0046] In some embodiments, the electric energy collection mechanism includes a coil bracket 4 and a coil mounting disk 5. Both sides of the coil mounting disk 5 are fixed to a pair of side supports 8, and the coil bracket 4 is fixed to the top of the side of the coil mounting disk 5 by bolts to form a coil tool. The front end of the linear motor is fixed to the coil mounting disk 5. By using the coil bracket 4, the electric energy generated during the operation of the TENG can be effectively collected through the coil on the coil bracket 4, improving the energy collection efficiency. The collected electric energy is fed back to the battery or other devices through the connected circuit system to realize the recycling of energy, further improving the energy utilization efficiency of the TENG device.

[0047] In some embodiments, the side support 8 is evenly spaced with a plurality of connection holes three in the vertical direction, and the coil mounting disk 5 is evenly spaced with a plurality of coil mounting holes matching the connection holes three in the circumferential direction. The fastener three passes through the coil mounting hole and the connection hole three to fix the coil mounting disk 5 at a preset position. By connecting the outside of the coil mounting disk 5 to the side support 8, the coil tool is firmly fixed by the side support 8 to ensure its stability during use, and the coil mounting disk 5 can move vertically on the side support 8. Since both ends of the linear motor are fixed to the linear motor support 3 and the side support 8 respectively, the vertical movement of the linear motor can be driven by the vertical movement of the coil mounting disk 5 on the side support 8.

[0048] In some embodiments, a plurality of connection holes four are evenly spaced on the desktop at the other end of the substrate 2, and the bottom of the rear side bracket 7 after collision is provided with rear side bracket mounting holes matching the connection holes four. The fastener four passes through the rear side bracket mounting hole and the connection hole four to fix the rear side bracket 7 after collision at a preset position.

[0049] In some embodiments, a plurality of connection holes five are evenly spaced in the vertical direction on the side of the rear side bracket 7 after collision that contacts the sensor moving block 6, and the side of the sensor moving block 6 is provided with sensor moving block mounting holes matching the connection holes five. The fastener five passes through the sensor moving block mounting hole and the connection hole five to fix the sensor moving block 6 at a preset height. The sensor moving block 6 is installed on the rear side bracket 7 after collision through a sensor fixing member. The sensor moving block 6 can move with the movement of the rear side bracket 7 after collision and can move vertically on the rear side bracket 7 after collision. As an example, the fastener five uses a screw. After removing the screw, the rear side bracket 7 after collision can be moved horizontally, and the horizontal movement directions of the rear side bracket 7 after collision and the side support 8 are the same.

[0050] It should be noted that the above connection structures using connection holes two to five have the same or similar technical effects as the moving block connection structure using connection hole one, so they will not be elaborated here.

[0051] Based on the same inventive concept, an embodiment of the present invention provides a test method using the above-mentioned bracket for the collision test of a triboelectric nanogenerator. During the test, first determine the height and horizontal position of the linear motor and the triboelectric nanogenerator, and then install each structure based on their positions. The method includes the following steps:

[0052] S1. Determine the installation positions of the linear motor and the triboelectric nanogenerator according to the test requirements;

[0053] S2. According to the installation positions of the linear motor and the triboelectric nanogenerator, install the moving block 1 on the motor support plate, and install the electric energy collection mechanism on the side support 8; install the side support 8 on both sides at one end of the substrate 2; install the post-collision rear bracket 7 on the other end of the substrate 2; install the sensor moving block 6 on the post-collision rear bracket 7;

[0054] S3. Install the linear motor on the moving block 1, and install the triboelectric nanogenerator on the sensor moving block 6 to start the collision test.

[0055] The bracket provided in the above embodiment of the present invention is an adjustable motor bracket. By adjusting the moving block and the coil mounting plate to drive the linear motor to move in the vertical direction, a movable side support is designed. The movement of the side support on the substrate drives the linear motor to move in the horizontal direction. Thus, through the adjustable support structure, the vertical and horizontal positions of the linear motor can be accurately and flexibly adjusted according to the test requirements or actual use needs, significantly improving the applicability, practicability and working efficiency of the device; the coil tool is used to collect the electric energy generated by the TENG work, which can further improve the efficiency, making the adjustment work both rapid and accurate. Through the combination of structures with multiple adjustment functions, the vertical and horizontal positions of the linear motor in the TENG collision test can be accurately and quickly adjusted. In addition, the bracket structure is simple and stable, solving the deficiencies of traditional linear motor brackets in terms of adjustment flexibility and stability, with high flexibility and stability, and also having the advantages of simple operation, high adjustment accuracy, long service life, etc., which can effectively improve the efficiency and accuracy of the TENG collision test, while reducing the complexity and cost of equipment maintenance.

It should be understood that the present invention is not limited to the above specific embodiments, and those skilled in the art can make various deformations or modifications within the scope of the claims, which do not affect the essence of the present invention. The above preferred features can be used in any combination without conflict.
