Description

Technical Field

[0001] This utility model relates to the field of drop protection technology, and more specifically, it relates to a drop-proof structure and a battery charger having the drop-proof structure. Background Technology

[0002] In industrial production and daily life, the normal operation of electrically driven equipment relies heavily on batteries, and battery chargers, as key devices ensuring battery power, are of paramount importance in terms of safety and durability. Because plug-and-play battery chargers are frequently moved, and to achieve good heat dissipation and cost control, they are often made of plastic, resulting in relatively weak drop resistance. In particular, highly integrated battery chargers have delicate internal structures, and the impact of drops can easily damage internal components, affecting the normal use of the equipment. Currently, most drop protection solutions for battery chargers employ a fully enclosed spring-loaded cushioning structure. However, this structure has significant drawbacks: it is bulky, increasing the charger's thickness; the installation process is cumbersome, hindering rapid assembly; its heat dissipation is poor, leading to heat buildup during operation; and its versatility is limited, only suitable for chargers of a fixed size, failing to meet the drop protection requirements of chargers of different specifications. Therefore, there is an urgent need for a drop protection structure that is small in size, easy to install, has good heat dissipation, and is highly versatile, to address the problems of existing technologies.

[0003] Therefore, in order to solve the above-mentioned technical problems, this utility model proposes a drop-proof structure and a battery charger having the drop-proof structure. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a drop-proof structure and a battery charger having the drop-proof structure.

[0005] To achieve the above objectives, the present invention provides the following technical solution: In a first aspect, a drop-proof structure for a charger includes one or more elastic bands and protective components that cooperate with the elastic bands; each elastic band is provided with at least two protective components, each protective component has a fitting groove, each protective component is fastened to the charger through the fitting groove, and the protective components on the same elastic band are fastened to the charger in opposite directions, so that each elastic band can be fixed independently; Each of the protective components has a connecting groove for the elastic band to pass through, and each of the protective components is slidably connected to the elastic band.

[0006] Furthermore, the protective component is a corner protector block, which is an inseparable whole, and the edges of the corner protector block are resilient.

[0007] Alternatively, the protective component is a corner protector assembly, which is divided into corner protector A and corner protector B, and corner protector A and corner protector B are connected by an elastic element; The fitting groove is composed of groove A and groove B, with groove A formed on corner protector A and groove B formed on corner protector B; the connecting groove is composed of through groove A and through groove B, with through groove A formed on corner protector A and through groove B formed on corner protector B.

[0008] Furthermore, when there are two or more elastic bands, the intersecting portions of the elastic bands are connected by fixed points.

[0009] Furthermore, when there are two or more elastic bands, the intersecting portions of the elastic bands are not fixedly connected.

[0010] Furthermore, on each of the elastic bands, one of the protective members is provided with a limiting mechanism, and the protective member has a sliding groove. The limiting mechanism includes a locking block disposed in the sliding groove. The locking block is rotatably disposed in the sliding groove by a torsion spring. One end of the elastic band is fixed to the protective member, and the other end of the elastic band passes through the other protective members on the elastic band, and the other protective members are slidably connected to the elastic band. The other end of the elastic band passes between the locking block and the sliding groove, and the torsion spring drives the locking block to abut against the surface of the elastic band.

[0011] Furthermore, the elastic band is provided with a storage component for storing the elastic band.

[0012] Furthermore, an elastic layer is provided inside the bonding groove.

[0013] Secondly, a battery charger with a drop-proof structure is provided, including a charger body, on which the aforementioned drop-proof structure is provided.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. The core inventive point of this application lies in the combination of an elastic band and an adjustable protective component, which effectively solves the problems of large size, inconvenient installation, poor heat dissipation, and weak versatility of existing drop-proof structures while ensuring drop protection. Specifically, the protective component only fits the corner of the charger body, and the contact area between the elastic band and the charger surface is small, which avoids increasing the thickness of the charger and ensures heat dissipation performance. The elastic band can be installed independently, and the protective component can slide on the elastic band. The length of the elastic band can be adjusted by a limiting mechanism, so that the structure can be adapted to chargers of different sizes, making it highly versatile. At the same time, the overall structure is simple, easy to install, and does not require complicated assembly procedures, significantly improving practicality and applicability.

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.

[0018] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure).

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0021] Furthermore, the technical solutions of the various embodiments of this utility model can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0022] like Figure 1-8 As shown, electrically driven equipment is indispensable in both industry and daily life, with batteries being the core lifeline and battery chargers being the key to ensuring the operation of the entire device. Especially for plug-and-play battery chargers, their location is usually not fixed and they need to be moved. Because battery chargers are typically made of plastic for good heat dissipation and cost reduction, they can be severely damaged if accidentally dropped, especially highly integrated chargers with delicate internal structures; the impact of a drop can damage internal components.

[0023] Currently, battery chargers use a fully enclosed spring-loaded cushioning structure. However, this structure is not only bulky, increasing the thickness of the original battery charger, but also inconvenient to install and has poor heat dissipation. In particular, it lacks versatility, only being suitable for battery chargers of a fixed size.

[0024] To address the aforementioned problems, this application proposes a drop-proof structure for a charger and a battery charger with a drop-proof structure. Please refer to [link / reference]. Figure 1 The device includes one or more elastic bands 200, each elastic band 200 having at least two protective elements 100, which are corner protectors 100' or corner protector assemblies 100'. Each protective element 100 has a fitting groove 101, and each protective element 100 is fastened to one corner of the charger body 800 through the fitting groove 101. The protective elements 100 on the same elastic band 200 are fastened to the charger body 800 in opposite directions, so that each elastic band 200 can be installed independently.

[0025] At the same time, the elastic bands 200 can be fixed together at the intersection points of each elastic band 200 through fixing points 300 to form a whole.

[0026] To facilitate adjustment according to the size of the battery charger, unlike the above, a connecting groove 102 can be opened on the protective component 100. The connecting groove 102 passes through the protective component 100, and then an elastic band passes through the connecting groove 102, so that the protective component 100 can slide on the elastic band to adjust the position between the protective components 100, thereby making targeted adjustments.

[0027] Because the corner curvature of different battery chargers is inconsistent, or the corner is a right angle, an elastic layer 500 is provided in the bonding groove 101 to make the protective component 100 fit better with the charger body 800. When the bonding groove 101 contacts the charger body 800, the outer wall of the charger body 800 will squeeze the elastic layer 500, thereby increasing the contact area between the charger body 800 and the protective component 100 and enhancing the cushioning effect. In addition, the elastic band 200 pulls the protective component 100 against the inner wall of the charger body 800, which will make the elastic layer 500 fit more precisely with the charger body 800.

[0028] In summary, the protective component 100 is attached to the charger body 800, and the elastic band 200 provides tension, thus providing stress to the charger body 800 and enhancing its drop resistance. Furthermore, this drop-proof structure is small in size and easy to carry. Since only the protective component 100 is attached to the corners of the charger body 800, and only part of the elastic band 200 contacts the surface of the charger body 800, it does not increase the thickness of the charger body 800 and does not affect the charger's heat dissipation capacity.

[0029] In the first case, the protective component 100 is a corner protector 100'. The edge of the corner protector 100' is flexible and can adapt to the corner of the charger body 800.

[0030] However, for charger bodies 800 that are either thinner (usually less than 6cm) or thicker (usually greater than 12cm), in order to ensure that the protective component 100 fits the charger body 800 better, a second approach is used. Unlike the previous embodiment, the protective component 100 is a corner protector assembly 100``, such as... Figure 8 As shown, the corner protector assembly 100 includes corner protector A110 and corner protector B120. Corner protector A110 and corner protector B120 are mirror images of each other, and an elastic member 400 is provided between corner protector A110 and corner protector B120. The elastic member 400 can pull corner protector A110 and corner protector B120 together, so that corner protector A110 and corner protector B120 can be tightly attached to the charger body 800. Corner protector A110 has a groove A111, and corner protector B120 has a groove B121. Grooves A111 and B121 together form a fitting groove 101, and corner protector A110 and corner protector B120 can be fastened to the charger body 800 through grooves A111 and B121.

[0031] The corner protector A110 has a through groove A112 for the elastic band 200 to pass through, and the corner protector B120 has a through groove B122 for the elastic band 200 to pass through. The through grooves A112 and B122 together form a connecting groove 102, through which the elastic band 200 passes. In use, the corner protectors A110 and B120 are first pried apart, and the elastic element 400 is stretched to move the corner protectors A110 and B120 away from each other. Then, the corner protectors A110 and B120 are snapped onto the charger body 800. After releasing the corner protectors A110 and B120, they are snapped onto the charger body 800 by the elastic force of the elastic band 200 restoring its deformation. This completes the fixation of corner protectors A110 and B120 to the charger body 800. Repeat this process to fix all corner protectors A110 and B120 to the charger body 800. Figure 4 As shown, the corner protectors A110 on each elastic band 200 are arranged opposite each other, so that the multiple elastic bands 200 form a cross structure. This completes the installation of the drop-proof structure on the battery charger body 800. Other operations are the same as in the above embodiment. It is worth noting that in the above embodiment, one end of the elastic band 200 passes through the connecting groove 102. In this embodiment, the connecting groove A112 and the connecting groove B122 can be considered together as the connecting groove 102 in the above embodiment, and the corner protectors A110 and B120 can be considered together as the protective member 100 in the above embodiment.

[0032] The elastic band 200 is made of a deformable material, which can be in the form of a strip or a rope.

[0033] However, since the stretching range of the elastic band 200 is limited, it cannot fully adapt to most charger bodies 800. In the first case, if the elastic band 200 is relatively long, for example, after a protective component 100 on one elastic band 200 is fastened to the charger body 800, the elastic band 200 remains in a slack state. In the second case, if the elastic band 200 is relatively short, for example, after a protective component 100 on one elastic band 200 is fastened to the charger body 800, it becomes difficult for other protective components 100 on the same elastic band 200 to be fastened to the charger body 800. To resolve the above issues, please refer to Figures 5 to 7 Unlike the previous embodiment, one end of the original elastic band 200 is fixed to one of the protective components 100, and a limiting mechanism 600 is provided on the protective component 100. The other end of the elastic band 200 passes through the connecting groove 102 on the other protective component 100, and one end of the elastic band 200 returns to the protective component 100, where it is limited by the limiting mechanism 600. The elastic band 200 can be pulled as needed to lengthen the distance between one end of the elastic band 200 and the limiting mechanism 600, thus shortening the elastic band 200. Conversely, shortening the distance between one end of the elastic band 200 and the limiting mechanism 600 lengthens the elastic band 200, allowing for flexible adjustment as required.

[0034] The limiting mechanism 600 can be a combination of a locking block 601 and a torsion spring 602. One of the protective components 100 has a groove 103. The locking block 601 is positioned in the groove 103 via the torsion spring 602, and the locking block 601 can rotate within the groove 103 via the torsion spring 602. The torsion spring 602 provides pressure to the locking block 601 within the groove 103. Lifting the locking block 601 compresses the torsion spring 602, creating a gap between the locking block 601 and the groove 103. The elastic band 200 is then passed through this gap. Releasing the locking block 601 causes it to press against the elastic band 200 under the force of the torsion spring 602, thus limiting the elastic band 200.

[0035] When the length of the elastic band 200 needs to be adjusted, lift the locking block 601 and pull the elastic band 200 to achieve the adjustment. This allows it to fit various sizes of battery charger bodies 800. Additionally, to prevent the elastic band 200 from becoming too long, a storage component 700 can be provided on the elastic band 200. Please refer to [link / reference needed]. Figure 7 By passing one end of the elastic band 200 through the storage component 700, the end of the elastic band 200 can be limited.

[0036] The elastic element 400 can be a spring, rubber band, or rubber, the elastic band 200 can be rubber or rubber band, and the elastic layer 500 can be sponge or rubber.

[0037] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or equivalent variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are considered equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
