Description

Technical Field

[0001] This utility model relates to the technical field of inverter transportation devices, specifically to a home storage inverter packaging box with damping and vibration reduction. Background Technology

[0002] As a core component of new energy systems, home energy storage inverters are susceptible to external vibrations and impacts during transportation and storage, which can damage or degrade the performance of their internal precision components. To improve protection, existing technologies often employ packaging structures such as foam filling and fixed brackets. However, traditional solutions often lack active dissipation mechanisms for multi-directional vibration energy and are difficult to adapt to the size variations of inverters of different specifications, resulting in limited vibration reduction effects. This is especially true for high-power home energy storage inverters, which are heavy and have complex structures. The rigid clamping of conventional packaging boxes can easily amplify the impact load due to resonance during transportation, thus increasing the risk of equipment damage.

[0003] The clamping structure of existing home energy storage inverter packaging boxes mostly adopts a fixed limit or single-direction adjustment design, which cannot simultaneously meet the size adaptation requirements of the inverter in the length and width directions. This insufficient clamping state will prevent the damping and vibration reduction structure from absorbing vibration energy evenly, and may even cause double damage to the packaging box and the equipment due to local stress concentration.

[0004] In view of this, a packaging box for a home energy storage inverter with damping vibration reduction is proposed. Utility Model Content

[0005] The purpose of this invention is to solve the problem that the clamping structure of the packaging box for home energy storage inverters cannot achieve adaptive and coordinated adjustment in the length and width directions, resulting in uneven absorption of vibration energy and risk of equipment damage.

[0027] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0028] Please see Figure 1-5 .

[0029] This utility model relates to a damped and vibration-reducing packaging box for a home energy storage inverter. It includes a packaging box body 1 and a carrier box 101 placed inside the packaging box body 1. A damping base 102 is placed at the bottom of the carrier box 101, and a placement box 103 is placed above the damping base 102. The placement box 103 contains a first clamping component 2 and a second clamping component 3. The first clamping component 2, located inside the placement box 103, includes a first limiting plate 21 and a second limiting plate 22 slidably disposed on the inner wall of the placement box 103. A first bidirectional screw 26, rotatably connected inside the placement box 103, is used to drive the first limiting plate 21 and the second limiting plate 22 to move closer or further apart. The first clamping component 2 is used to limit the length of the inverter. The second clamping component 3, located on the first limiting plate 21, includes two components slidably disposed on the first limiting plate 21. The first limiting plate 21 has two third limiting plates 31. A second bidirectional screw 35 is rotatably connected to the first limiting plate 21 to drive the two third limiting plates 31 to move closer or further apart. The second clamping component 3 is used to limit the width of the inverter. With this configuration, the first and second limiting plates 22 can be driven to move synchronously in opposite directions along the length direction by the first bidirectional screw 26, and the third limiting plate 31 can be driven to move synchronously in opposite directions along the width direction by the second bidirectional screw 35. This forms a clamping system that can be independently adjusted in both length and width. In other words, by utilizing the positive and negative thread characteristics of the bidirectional screw, the limiting plates can be moved with high precision and symmetrically, ensuring that the inverter is fixed in the center and avoiding the offset problem caused by unilateral force. In addition, the dual-motor drive can adapt to the length and width specifications of inverters of different sizes, solving the problem that traditional fixed limiting cannot be compatible with multiple models of equipment.

[0030] The first limiting plate 21 and the second limiting plate 22 are fixedly connected to the first slider 27 with a T-shaped cross section on both sides. The placement box 103 is provided with a first sliding groove 28 that matches the size of the first slider 27. This arrangement can constrain the movement trajectory of the first and second limiting plates 22 through the cooperation of the T-shaped slider and the sliding groove, ensuring that they slide only in a straight line during the adjustment process.

[0031] Secondly, a first motor 25 is fixedly connected to the inner wall of the placement box 103. The output end of the first motor 25 is fixedly connected to one end of the first bidirectional screw 26, and the other end of the first bidirectional screw 26 is rotatably connected to the inner wall of the placement box 103. The threads at both ends of the first bidirectional screw 26 are reversed, and the two ends of the first bidirectional screw 26 are respectively connected to two threaded sleeves through ball screws. The two threaded sleeves are respectively fixedly connected to the first limiting plate 21 and the second limiting plate 22. Specifically, the first motor 25 drives the first bidirectional screw 26, and the rotational motion is converted into the linear displacement of the limiting plate through the ball screw threads.

[0032] Furthermore, both the first limiting plate 21 and the second limiting plate 22 are elastically provided with first clamping plates 23 for clamping the two ends of the inverter by means of a first spring 24. The elastic deformation of the spring can absorb the high-frequency micro-vibration between the inverter and the clamping plate, reducing the risk of resonance. In addition, the elastic contact avoids excessive local stress caused by rigid clamping, preventing the inverter shell from deforming due to stress concentration.

[0033] Furthermore, each of the two third limiting plates 31 is fixedly connected with a second slider 36. The first limiting plate 21 is provided with a second sliding groove 37 that matches the size of the second slider 36. The second limiting plate 22 is provided with a channel 38 for the movement of the two third limiting plates 31. Through the cooperation of the second slider 36 and the sliding groove, the movement direction of the third limiting plate 31 during width adjustment is constrained.

[0034] In addition, a second motor 34 is fixedly connected to the first limiting plate 21. The output end of the second motor 34 is fixedly connected to one end of the second bidirectional screw 35, and the other end of the second bidirectional screw 35 is rotatably connected to the first limiting plate 21. The threads at both ends of the second bidirectional screw 35 are reversed. Both ends of the second bidirectional screw 35 are connected to a screw sleeve through a ball screw. The two screw sleeves are fixedly connected to the two third limiting plates 31 respectively. With this configuration, the second bidirectional screw 35 is driven by an independent motor in the width direction to realize the automatic adjustment of the third limiting plate 31.

[0035] Furthermore, each of the two third limiting plates 31 is elastically provided with a second clamping plate 32 for clamping the two sides of the inverter via a second spring 33. This arrangement, together with the first clamping plate 23, forms a composite buffer layer in the longitudinal and transverse directions, suppressing the transmission of multi-directional vibrations.

[0036] Working principle:

[0037] The packaging box achieves adaptive fixation and multi-level vibration reduction through the synergistic effect of a motor-driven bidirectional screw and an elastic clamping structure. During operation, the inverter is placed in the placement box 103. The first motor 25 drives the first bidirectional screw 26 to rotate, driving the first limiting plate 21 and the second limiting plate 22 to slide towards each other along the T-shaped slide groove. The clamping plate of the first spring 24 elastically fits against both ends of the inverter, completing the length direction limitation. Subsequently, the second motor 34 drives the second bidirectional screw 35 to push the third limiting plate 31 to move laterally. The clamping plate of the second spring 33 adaptively clamps both sides of the inverter, forming a bidirectional locking in both length and width. During transportation, the damping base 102 absorbs low-frequency vibration energy through a highly elastic material, while the residual high-frequency vibration is transmitted to the first spring 24 and the second spring 33 through the elastic clamping plate, and further buffered by spring deformation. At the same time, the rigid guiding structure of the bidirectional screw and the slide groove suppresses equipment displacement and avoids resonance amplification of impact. When external vibration causes the inverter to be unbalanced, the elastic clamping plate dynamically adjusts the clamping force distribution through local compression. Combined with the characteristics of the damping base 102, it forms a multi-level protection chain of rigid limit, elastic buffer and damping dissipation, ensuring the safety and stability of the equipment in complex transportation environments.

[0038] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
