Description

Technical Field

[0001] This utility model relates to the field of mobile phone accessories technology, and in particular to a drop-proof mobile phone case with a four-corner double force-relief buffer structure. Background Technology

[0002] Mobile phones have become an indispensable daily tool for modern people, and their security, especially their ability to protect against accidental drops, is a key concern for users. Statistics show that when a mobile phone is dropped, its four corners are the first parts to hit the ground and bear the greatest impact. The vast majority of screen breakage and damage to internal components are caused by impacts to the corners.

[0003] Most existing shockproof phone cases use a single-material cushioning solution, simply absorbing impact by increasing the thickness of the soft rubber at the corners. However, this solution has certain technical drawbacks: the material itself has limited deformation space and energy absorption efficiency. When subjected to high-intensity impacts, energy cannot be effectively dissipated and will still be directly transferred to the phone body, causing damage. In addition, this design method does not fully consider impact force guidance and energy dissipation in stages, resulting in limited cushioning effect; finally, the anti-slip design of the back panel often sacrifices wear resistance, or the smooth back panel makes it easy to slip out of your hand.

[0004] Therefore, there is an urgent need in this field for a new type of shockproof phone case to enhance the protection of mobile phones. Utility Model Content

[0005] This utility model overcomes the shortcomings of the prior art and provides a drop-proof phone case with a four-corner double force-relief buffer structure, which can overcome the technical defects mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] A drop-proof phone case with a four-corner double force-relief buffer structure includes a phone case body, the phone case body having an accommodating cavity for accommodating the phone, and a raised external protective block provided at each of the four outer corners of the phone case body. The outer surface of the external protective block is formed with a groove texture that resembles a tire. When subjected to external impact, the texture bends, is compressed, and the grooves close, thus deforming to achieve the first stage of impact energy absorption and diffusion.

[0008] The four corners of the back panel of the phone case body, facing the external protective block, form an inwardly recessed buffer cavity structure. When the impact force is transmitted through the external protective block, the energy dissipation and impact stress dispersion in the second stage are achieved by the retraction or bending of the cavity wall in the buffer cavity structure.

[0009] Furthermore, the cross-sectional shape of the buffer cavity structure is honeycomb-shaped, wavy, or X-shaped.

[0010] Furthermore, the external protective block is made of highly elastic TPU or silicone material.

[0011] Furthermore, the outer back panel of the phone case body is provided with a micro-textured pattern resembling rhinoceros leather.

[0012] Furthermore, the roughness Ra value of the micro-texture is between 3.2 μm and 12.5 μm.

[0013] Furthermore, the external protective block, the buffer cavity structure, and the phone case body are integrally injection molded into a single unit.

[0014] Furthermore, the phone case body has a ring-shaped protective edge pattern around the opening corresponding to the position of the phone camera module.

[0015] Furthermore, the bottom of the back panel of the phone case body is provided with at least one recessed platform, the bottom surface of the recessed platform is coplanar with the bottom surface of the annular protective edge, so that the phone case body can be placed stably and horizontally.

[0016] Furthermore, there are two sunken platforms, which are symmetrically arranged on the left and right sides of the bottom of the back plate.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] This invention achieves efficient and progressive dissipation of impact energy through the synergistic effect of the external protective block and the buffer cavity structure, reducing the final impact force transmitted to the phone body and improving upon the shortcomings of traditional single buffer materials or structures. In addition, the external protective block and the buffer cavity structure are designed at the four corners of the phone that are most vulnerable to damage. The external protective block absorbs and diffuses the impact, while the buffer cavity structure guides and disperses stress through its specific geometry, avoiding point damage to the corners and internal components caused by stress concentration, resulting in good protection.

[0029] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0030] like Figures 1 to 7 As shown, this utility model claims protection for a drop-proof phone case with a four-corner double-impact buffer structure, including a phone case body with an internal cavity for accommodating and securing the phone; wherein, at each of the four outer corners of the phone case body, there is an independent and outwardly protruding external protective block 1, the external protective block 1 is made of high-elasticity TPU or silicone material by injection molding, and the outer surface of the external protective block 1 is processed with tire-like groove texture 101. When the corner of the phone is accidentally dropped and hits the ground, this external protective block 1 will first contact the ground. Under pressure, the raised ribs of the tire-like groove texture 101 will bend and compress, and the grooves will close. Thus, through the elastic deformation of the material itself, a portion of the concentrated impact kinetic energy is converted into heat energy and dispersed throughout the contact surface, thereby achieving the first stage of impact energy absorption and initial diffusion.

[0031] At the four corners of the inner back panel of the phone case, opposite the aforementioned outer protective block 1, there is an inwardly recessed buffer cavity structure 2. The cross-sectional shape of this buffer cavity structure 2 can be a regularly distributed honeycomb pattern, a continuously undulating wave shape, or a cross-radiating X-shape. When the impact of the first stage is not completely absorbed, the remaining impact force will be transmitted to the buffer cavity structure 2 directly behind the outer protective block 1. The buffer cavity structure 2 provides a collapse space for further deformation. Under pressure, its cavity wall will shrink, bend, or even partially collapse. Through this structural sacrifice, the remaining impact energy is dissipated, so as to guide the point-like concentrated stress and disperse it in all directions, realizing the second stage of deep energy dissipation and impact stress dispersion.

[0032] In this embodiment, in order to ensure structural strength and integrity, the external protective block 1, the buffer cavity structure 2, and the phone case body are preferably integrally injection molded into a complete whole.

[0033] In this embodiment, the outer back panel surface of the phone case body is uniformly provided with a micro-textured texture 3 resembling rhinoceros leather. The roughness Ra value of the micro-textured texture 3 is preferably controlled between 3.2μm and 12.5μm. The purpose of the micro-textured texture 3 is twofold: firstly, the uneven structure prevents the back panel surface from fully contacting a flat surface, thereby effectively resisting daily wear and scratches and maintaining its aesthetic appeal; secondly, it increases the friction between the palm and the phone case, providing a stable grip and reducing the risk of accidental drops from the outset.

[0034] Meanwhile, at the location of the phone case body corresponding to the phone's camera module, a ring-shaped protective edge 4 is formed around the lens opening. In actual design, the height of the ring-shaped protective edge 4 is designed to be higher than the surface of the phone's camera lens, so that when the phone is placed flat on a table, the ring-shaped protective edge 4 contacts the table, preventing the camera component from directly scratching the table.

[0035] In addition, at least one recessed platform 5 is provided at the bottom of the back panel of the phone case body, from Figure 7 See, the bottom surface of the sunken platform 5 and the bottom surface of the ring-shaped protective edge 4 are on the same horizontal plane, ensuring that when the phone case is placed flat on the table, the ring-shaped protective edge 4 and the sunken platform 5 can serve as support points at the same time, forming a stable support plane, so that the phone case can always be placed stably and horizontally.

[0036] In this embodiment, the number of sunken platforms 5 is set to two. These two sunken platforms 5 are symmetrically arranged on the left and right sides of the bottom of the back panel, thus forming a stable three-point support or a wider support surface together with the annular protective edge 4 of the camera area, which helps to improve the static stability when placed. In addition, the sunken platforms 5 can also provide a natural support for the index finger, which plays an auxiliary role in preventing the hand from slipping.

[0037] This invention achieves efficient and progressive dissipation of impact energy through the synergistic effect of the external protective block 1 and the buffer cavity structure 2, reducing the final impact force transmitted to the mobile phone body and improving the shortcomings of traditional single buffer materials or structures. In addition, the external protective block 1 and the buffer cavity structure 2 are designed at the four corners of the mobile phone that are most vulnerable to damage. The external protective block 1 absorbs and diffuses the impact, while the buffer cavity structure 2 guides and disperses stress through its specific geometry, avoiding point damage to the corners and internal components caused by stress concentration, thus providing good protection.

[0038] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. However, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
