Description

Technical Field

[0001] This utility model relates to the field of testing device technology, and more specifically, to a pulse injection testing device for new energy battery packs. Background Technology

[0002] Electromagnetic pulses (EMPs) are characterized by their wide coverage, high peak field strength, and broad frequency range, posing a significant threat to electronic systems. They can even render satellite electronic equipment and ground command systems inoperable. Therefore, studying the interference and damage mechanisms of EMPs on electronic systems and developing effective protection methods based on this understanding is crucial. EMP measurement is integral to the entire EMP testing process and forms the basis for evaluation and assessment. Current EMP measurements primarily employ shielded cables or optical fibers to transmit analog signals acquired by a front-end measurement probe back to a data processing terminal such as an oscilloscope.

[0003] During the pulse injection process of new energy battery packs, testing devices such as oscilloscopes are also required. Some existing oscilloscopes have a rotating handle on the top or side for portability, while others have a shoulder strap. However, the shoulder strap cannot be rolled up, leaving it exposed to the outside. This can easily cause the oscilloscope to snag during use, posing a potential hazard. Utility Model Content

[0004] The purpose of this invention is to provide a pulse injection testing device for new energy battery packs to solve the problems mentioned in the background art.

[0005] Some existing oscilloscopes have a rotating handle on the top or side for portability, while others have a shoulder strap. However, the strap cannot be rolled up, leaving it exposed and prone to snagging during use, posing a potential safety hazard.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A pulse injection testing device for new energy battery packs includes an oscilloscope body. The oscilloscope body has an internal groove, and a rotating shaft is housed within the groove. The rotating shaft is rotatably connected to the oscilloscope body. A shoulder strap is fixedly connected to the outside of the rotating shaft, with the other end of the strap rotatably connected to the oscilloscope body. Two shoulder straps are symmetrically distributed. A coil spring is sleeved outside the rotating shaft, located between the groove and the shoulder strap. The coil spring drives the rotating shaft to rotate, automatically retracting the shoulder strap into the groove to prevent snagging. One end of the coil spring is fixedly connected to the oscilloscope body, and the other end is fixedly connected to the rotating shaft. A cover plate is detachably connected inside the groove. The cover plate has a first through slot, and a rod is slidably connected inside the first through slot. A slot is provided inside the rotating shaft, and the slot works in conjunction with the rod to limit the position of the rotating shaft.

[0008] Preferably, a circular plate is fixedly connected to the outer end of the insertion rod away from the rotating shaft, and a tension spring is sleeved on the outer side of the insertion rod between the cover plate and the circular plate. One end of the tension spring is fixedly connected to the cover plate, and the other end of the tension spring is fixedly connected to the circular plate. The tension of the tension spring facilitates the automatic engagement of the insertion rod with the slot.

[0009] Preferably, the outer end of the insertion rod near the pivot is chamfered, which allows it to be inserted into the slot more smoothly.

[0010] Preferably, the cover plate has a second through groove inside, which is used in conjunction with the shoulder strap, and the shoulder strap extends to the outside through the second through groove.

[0011] Preferably, both the first through groove and the insert rod have square cross-sections. The square cross-sections of the first through groove and the insert rod are mainly used to limit the insert rod in the first through groove, so that the insert rod can only slide back and forth in the first through groove and will not rotate.

[0012] Preferably, the outer side wall of the insertion rod is fitted with the inner side wall of the first through groove, and the insertion rod is tightly fitted with the first through groove. When the insertion rod slides back and forth in the first through groove, the inner wall of the first through groove can be used to limit the insertion rod, so that the insertion rod can slide smoothly.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] In this application, the pull rod is pulled apart from the slot on the rotating shaft, releasing the limitation of the pull rod and slot on the rotating shaft. Then, the strap is pulled until it is completely pulled out. After releasing the circular plate, the tension of the spring will cause the pull rod to re-engage with the slot, thereby positioning the rotating shaft. At this time, the user can use the strap to carry the oscilloscope body on their body for portability. After use, the pull rod is pulled out again, and the rotating shaft will automatically retract the strap into the groove under the action of the coil spring, so that the strap is not directly exposed and avoids snagging.

[0022] 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.

[0023] Please see Figures 1 to 6A pulse injection testing device for new energy battery packs includes an oscilloscope body 1. A groove 2 is formed inside the oscilloscope body 1, and a rotating shaft 3 is disposed inside the groove 2. The rotating shaft 3 is rotatably connected to the oscilloscope body 1. A strap 4 is fixedly connected to the outside of the rotating shaft 3, and the other end of the strap 4 is rotatably connected to the oscilloscope body 1. There are two straps 4, symmetrically distributed. A coil spring 5 is sleeved on the outside of the rotating shaft 3, located between the groove 2 and the strap 4. The coil spring 5 drives the rotating shaft 3 to rotate, thereby using the rotating shaft 3 to... The shoulder strap 4 automatically retracts into the groove 2, thus preventing the shoulder strap 4 from getting caught. One end of the coil spring 5 is fixedly connected to the oscilloscope body 1, and the other end of the coil spring 5 is fixedly connected to the rotating shaft 3. A cover plate 6 is detachably connected inside the groove 2. A first through groove 7 is opened inside the cover plate 6. A plug rod 8 is slidably connected inside the first through groove 7. A slot 9 is opened inside the rotating shaft 3. The slot 9 works in conjunction with the plug rod 8. The position of the rotating shaft 3 is limited by the plug rod 8 and the slot 9 to prevent the pulled-out shoulder strap 4 from being automatically retracted.

[0024] Furthermore, a circular plate 10 is fixedly connected to the outer end of the insertion rod 8 away from the rotating shaft 3. A tension spring 11 is sleeved on the outer side of the insertion rod 8 between the cover plate 6 and the circular plate 10. One end of the tension spring 11 is fixedly connected to the cover plate 6, and the other end of the tension spring 11 is fixedly connected to the circular plate 10. Under the tension of the tension spring 11, it is beneficial for the insertion rod 8 to automatically engage with the slot 9.

[0025] Furthermore, a chamfer 12 is provided on the outer end of the insertion rod 8 near the rotating shaft 3. Under the action of the chamfer 12, the cross-section of the other end of the insertion rod 8 is smaller, so that it can be inserted into the slot 9 more smoothly.

[0026] Furthermore, a second through groove 13 is provided inside the cover plate 6. The second through groove 13 is used in conjunction with the shoulder strap 4. The second through groove 13 is a long strip structure, and the shoulder strap 4 extends to the outside through the second through groove 13.

[0027] Furthermore, both the first through groove 7 and the insert rod 8 have square cross-sections. The square cross-sections of the first through groove 7 and the insert rod 8 are mainly used to limit the insert rod 8 in the first through groove 7, so that the insert rod 8 can only slide back and forth in the first through groove 7 without rotating, thereby avoiding the tension spring 11 from being affected.

[0028] Furthermore, the outer side wall of the insertion rod 8 is fitted with the inner side wall of the first through groove 7, and the insertion rod 8 is tightly fitted with the first through groove 7. When the insertion rod 8 slides back and forth in the first through groove 7, the inner wall of the first through groove 7 can be used to limit the insertion rod 8, so that the insertion rod 8 can slide smoothly without shaking.

[0029] The steps for using this utility model are as follows: When using this new energy battery pack pulse injection testing device, the user can pull the plug rod 8 through the circular plate 10 to separate the plug rod 8 from the slot 9 on the rotating shaft 3, thereby releasing the restriction of the plug rod 8 and slot 9 on the rotating shaft 3. Then, pull the shoulder strap 4 until it is completely pulled out. At this time, after releasing the circular plate 10, the tension of the tension spring 11 will drive the plug rod 8 to re-engage with the slot 9, thereby positioning the rotating shaft 3. At this time, the user can use the shoulder strap 4 to carry the oscilloscope body 1 on their body for portability. After use, pull the plug rod 8 again, and under the action of the coil spring 5, the rotating shaft 3 will automatically retract the shoulder strap 4 into the groove 2, so that the shoulder strap 4 is not directly exposed and avoids snagging.
