Description

Technical Field

[0001] This utility model relates to the field of lithium-ion battery testing technology, specifically a novel vibration table sensor fixing fixture. Background Technology

[0002] Lithium-ion battery testing encompasses a wide range of aspects, typically including safety performance, electrical performance, environmental adaptability, mechanical performance, and lifespan testing. The specific testing items vary depending on the type of battery and its application. Among these, vibration testing plays a crucial role in mechanical performance testing. Vibration testing primarily simulates the reciprocating motion of an object near its equilibrium position. During mechanical vibration, the physical parameters of the vibrating object, such as displacement and velocity, undergo repeated changes, which can potentially cause various hazards in daily life and engineering projects. For example, vibration can exacerbate component fatigue and wear, and shorten the lifespan of machinery.

[0003] Currently, existing vibration testing equipment mainly consists of several parts, including a controller, power amplifier, fixed base, connecting rod, and sample mounting platform. Its main operating steps include powering on and setting parameters, installing the sample, and using adhesive to install the sensor. The specific testing process is as follows: turn on the controller → set the target spectrum → set the schedule → set the engineering units → glue the sensor → start the test → observe the test process for any abnormalities → test ends. Finally, observe the external structure of the battery for any damage or cracking, and for any signs of fire, explosion, or leakage.

[0004] However, this traditional vibration testing method has many problems and drawbacks. Regarding sensor installation, existing sensors use a top-out wiring method, which greatly limits the installation location. In actual testing, when installing different samples, operating process fastening devices, or facing different vibration test displacements, it is necessary to reattach the sensor base, frequently disassembling and reassembling the sensor. This operation can easily damage the sensor, rendering it unusable, increasing testing costs, and affecting the continuity and efficiency of the test. Utility Model Content

[0005] The purpose of this invention is to provide a novel fixture for fixing vibration table sensors to solve the problems in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A novel vibration table sensor fixing fixture includes a sensor, a winding unit, and a take-up unit mounted on the vibration table. The sensor has a wiring sleeve on its side, and the sensor outputs a sensing line through the wiring sleeve. The sensing line is connected to the winding unit and the take-up unit in sequence.

[0007] Preferably, the winding unit includes a winding rod and a winding post. The end of the sensing wire away from the wiring sleeve is wound and fixed to the winding rod. The winding rod is fixed to the upper end of the winding post. The winding post is mounted on a vibration table. The bottom of the winding post outputs the sensing wire. The end of the sensing wire away from the winding post is connected to the take-up unit.

[0008] Preferably, the take-up unit includes a traction connector, which is located at the upper end of the take-up box. The traction connector connects the end of the sensor wire away from the winding post to the take-up box. The take-up box is fixed to the bottom of the vibration table, and a conduit is provided at the bottom of the take-up box. The conduit is used to guide the sensor wire to connect to external connection equipment of the vibration table.

[0009] Preferably, the sensing wires of the winding post and the traction joint are reserved with a length of 60mm.

[0010] Preferably, the surfaces of the winding rod and the winding post are provided with anti-slip texture.

[0011] Preferably, the conduit is a flexible metal hose with an outer layer of wear-resistant rubber.

[0012] Preferably, a steering buffer pulley is provided between the wiring sleeve and the winding rod. The steering buffer pulley is mounted on the vibration table and is used to adjust the direction of the conduit.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model installs a wiring sleeve on the side of the sensor, thereby leading the sensor wire out from the side of the sensor and protecting and fixing it with the wiring sleeve. This design not only avoids the collision risk that may be caused by the top wiring, but also makes the arrangement of the sensor wire more flexible and convenient, improving the safety and ease of use of the entire device.

[0014] 2. This utility model achieves orderly winding and automatic retraction of sensor wires by setting up a dedicated winding unit (including a winding rod and a winding post) and a take-up unit (including a traction connector and a retraction box). This not only avoids the messiness of the wire bundle, but also ensures that the sensor wires can freely expand and contract during vibration and will not be damaged due to excessive stretching or compression, thereby significantly improving the flexibility and reliability of sensor wire management.

[0015] 3. This utility model reserves an appropriate sensor wire length (such as 60mm) at the winding post and traction joint. This length is slightly greater than the alarm displacement of the vibration table, ensuring that even under the maximum vibration displacement, the sensor wire will not be stretched to the point of damage.

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0019] In one embodiment, such as Figure 1 As shown, a novel vibration table sensor fixing fixture includes a sensor 1, a winding unit, and a take-up unit mounted on the vibration table. The sensor 1 has a wiring sleeve 2 on its side. The sensor 1 outputs a sensing line 6 through the wiring sleeve 2. The sensing line 6 is connected to the winding unit and the take-up unit in sequence.

[0020] In this embodiment, sensor 1 is mounted on a vibration table via a sensor base. The sensor base is detachably mounted on the vibration table using bolts. A wiring sleeve 2 is designed on the side of sensor 1. The wiring sleeve 2 not only protects the connector of the sensor line 6, but also serves as a fixed point for the output of the sensor line 6. The wiring sleeve 2 and sensor 1 are detachably connected by threads.

[0021] The sensor wire 6 is led out from the wiring sleeve 2 and connected to the winding unit and the take-up unit in sequence to form a complete signal transmission path.

[0022] In an optional embodiment, the winding unit includes a winding rod 4 and a winding post 5. The end of the sensing wire 6 away from the wiring sleeve 2 is wound and fixed to the winding rod 4. The winding rod 4 is fixed to the upper end of the winding post 5. The winding post 5 is mounted on a vibration table. The bottom of the winding post 5 outputs the sensing wire 6. The end of the sensing wire 6 away from the winding post 5 is connected to the take-up unit.

[0023] It should be noted that the end of the sensor wire 6 furthest from the wiring sleeve 2 is securely wound around the winding rod 4, ensuring that the sensor wire 6 will not loosen or fall off during vibration. The winding rod 4 is fixed to the upper end of the winding post 5, which is stably mounted on the vibration table. This design allows the sensor wire 6 to be flexibly adjusted according to the movement of the vibration table while maintaining the stability of signal transmission. The bottom of the winding post 5 has an outlet for the sensor wire 6, allowing the sensor wire 6 to smoothly transition to the take-up unit.

[0024] In an optional embodiment, the take-up unit includes a traction connector 7, which is disposed on the upper end of the retractable cable box 8. The traction connector 7 connects the end of the sensor wire 6 away from the winding post 5 to the retractable cable box 8. The retractable cable box 8 is fixed to the bottom of the vibration table, and a cable tube 9 is provided at the bottom of the retractable cable box 8. The cable tube 9 is used to guide the sensor wire 6 to connect to the external connection equipment of the vibration table.

[0025] It should be noted that the traction connector 7 is located at the upper end of the shrink box 8, and its function is to securely connect the sensor wire 6, which is led out from the bottom of the winding post 5, to the shrink box 8. The traction connector 7 can be a displacement sensor connector, which can accurately sense the amount of extension and contraction of the sensor wire. The shrink box 8 is fixed to the bottom of the vibration table and has an internal automatic shrinkage mechanism that can automatically adjust the length of the sensor wire 6 according to its tension, preventing the sensor wire 6 from becoming too slack or too taut during vibration. The bottom of the shrink box 8 is also equipped with a conduit 9, which is used to guide the sensor wire 6 to the connection equipment outside the vibration table, ensuring smooth signal transmission.

[0026] In an optional embodiment, the sensing wire 6 of the winding post 5 and the traction connector 7 is reserved with a length of 60mm.

[0027] It should be noted that the sensor wire 6 is reserved with a length of 60mm. This design takes into account the expansion and contraction requirements of the sensor wire 6 during vibration, and avoids the problem of pulling or breaking due to insufficient length.

[0028] In an optional embodiment, the surfaces of the winding rod 4 and the winding post 5 are provided with anti-slip textures.

[0029] It should be noted that the surfaces of the winding rod 4 and the winding post 5 are provided with anti-slip textures, which further enhances the stability of the sensing wire 6 during the winding process and prevents it from sliding or falling off during vibration.

[0030] In an optional embodiment, the conduit 9 is a flexible metal hose with an outer layer of abrasion-resistant rubber.

[0031] It should be noted that this material selection ensures both the flexibility of the conduit 9 and enhances its wear resistance and service life. A steering buffer pulley 3 is also installed between the wiring sheath 2 and the winding rod 4.

[0032] In an optional embodiment, a steering buffer pulley 3 is provided between the wiring sleeve 2 and the winding rod 4. The steering buffer pulley 3 is mounted on a vibration table and is used to adjust the direction of the conduit 9.

[0033] It should be noted that the steering buffer pulley 3 is installed on the vibration table and can adjust the direction of the conduit 9 as needed to ensure that the sensor line 6 is not obstructed or damaged during transmission.

[0034] The above embodiments disclose a novel vibration table sensor fixing fixture, wherein the device power switch is turned on to start the vibration table control system. Subsequently, the parameters required for the test, including but not limited to vibration frequency, amplitude, and test time, are input through an external control device (such as a computer or dedicated controller).

[0035] Start the vibration table and allow it to vibrate according to the preset parameters. During this process, sensor 1, which is installed on the vibration table, will vibrate along with the table surface to capture various physical parameters (such as displacement, velocity, acceleration, etc.) during the vibration process.

[0036] It is particularly important to note that the wiring harness between sensor 1 and steering buffer pulley 3 should vibrate in the same plane to avoid the wiring harness from being twisted or pulled, which could affect the normal operation of the sensor or cause inaccurate data.

[0037] Any excess sensor wires on the vibration table should be neatly wound around the winding rod 4 and winding post 5. This ensures that when the vibration table vibrates, this portion of the sensor wires 6 will not vibrate, thus avoiding noise interference or data fluctuations caused by wire bundle vibration. It also guarantees the orderliness and stability of the sensor wires during vibration.

[0038] Above the shrink box 8, a certain length of sensor wire 6 (60mm in this example) needs to be reserved, slightly longer than the alarm displacement of the vibration table (51mm). This is to ensure that during vibration, even if the vibration table reaches its maximum displacement, the sensor wire 6 will not be stretched to the point of damage. The reserved sensor wire 6 is connected to the upper end of the shrink box 8 via a traction connector 7. The traction connector 7 uses a displacement sensor connector, which can accurately sense the amount of extension and contraction of the sensor wire. During vibration, the shrink box 8 will automatically adjust the rotation of its internal spool according to the tension of the sensor wire, thereby freely shrinking or releasing excess sensor wire 6, ensuring that the sensor wire 6 always maintains an appropriate degree of slack to adapt to displacement changes during vibration, and ensuring the accuracy and stability of the test data.

[0039] The above description is merely a specific embodiment of this application, but the scope of protection of this application 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 application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
