Description

Technical Field

[0001] This utility model relates to the field of injection molding technology, specifically to a shockproof shell. Background Technology

[0002] Cylindrical speakers are favored by consumers for their unique appearance and good sound quality, but due to their shape, they are not very stable when placed and are easily rolled over by slight touches or external forces. Once they roll off a table or other high surface, the speaker casing and internal circuitry are easily damaged, affecting the user experience and increasing repair costs. Currently, most speaker cases on the market mainly focus on dust and scratch protection, and there is still no simple and efficient solution to the problem of cylindrical speakers easily rolling and falling. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a shockproof shell.

[0004] The purpose of this utility model can be achieved through the following technical solution: a drop-proof shell, including two triangular side shells arranged opposite each other, connected by a connecting strip, a mounting ring integrally formed with the side shell in the middle, a metal bracket embedded in the mounting ring, a hollow buffer hole on the side shell located outside the mounting ring, and an outwardly extending skirt at the end of the side shell away from the connecting strip.

[0005] Preferably, a retaining edge is provided on one side of the mounting ring.

[0006] Preferably, the skirt edge is provided with shrinkage holes.

[0007] Preferably, the intersection of two adjacent surfaces on the side shell has an arc-shaped structure.

[0008] Preferably, the bottom of the side shell is provided with an anti-slip pad.

[0009] Preferably, the metal bracket has multiple through holes.

[0010] The beneficial effects of this utility model are: the triangular side shell provides a stable support surface, effectively preventing the speaker from rolling due to slight touch or external interference. At the same time, the hollow buffer holes on the side shell improve the deformation capability of the side shell. At the moment of drop, the material around the buffer holes will fully deform, converting the impact force into its own elastic potential energy, thereby playing a buffering role and further reducing the impact on the speaker.

[0018] Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be 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.

[0019] The technical solution of this utility model will be clearly and completely described below with reference to specific embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] See Figures 1 to 4As shown, the structure of this utility model is as follows: a drop-proof shell includes two triangular side shells 1 arranged opposite each other, connected by a connecting strap 2. A mounting ring 3 integrally formed with the side shell 1 is provided in the middle of the side shell 1, and a metal bracket 4 is embedded within the mounting ring 3. A hollowed-out buffer hole 5 is provided on the side shell 1 outside the mounting ring 3. A skirt 6 extending outwards is provided at the end of the side shell 1 away from the connecting strap 2. Specifically, the shell is made entirely of silicone material. Silicone material itself has high elasticity and flexibility. When the shell is impacted or dropped, the silicone absorbs the impact force through its own compression and deformation. The two triangular side shells 1 are arranged opposite each other and connected by the connecting strap 2, which can wrap around the speaker from both sides, providing a stable support surface and preventing the speaker from rolling. The integrally formed mounting ring 3 in the middle of the side shell 1 can tightly fit onto the speaker, serving to fix the speaker. The metal bracket 4 embedded within the mounting ring 3 enhances the strength and stability of the mounting ring 3, allowing the protective shell to better withstand external forces. The buffer hole 5 on the side shell 1, located outside the mounting ring 3, can absorb the impact force by increasing its deformation capacity when the speaker is dropped, thus improving the buffering effect and reducing the possibility of damage to the speaker. When the speaker is dropped vertically or laterally, the skirt 6 will contact the ground first and buffer the impact of the lateral drop by deforming the skirt 6.

[0021] like Figure 1 , Figure 4 As shown, a retaining edge 7 is provided on one side of the mounting ring 3. Specifically, the retaining edge 7 is located on one side of the mounting ring 3 and forms a limit with the edge of the speaker. When subjected to lateral impact, it prevents the speaker from sliding.

[0022] like Figure 1 , Figure 2 As shown, the skirt 6 has a crumple hole 8. Specifically, when the speaker is dropped vertically or sideways, the skirt 6 will contact the ground first. By opening the crumple hole 8 on the skirt 6, the structural strength of the material in this area is reduced, making the skirt 6 more prone to deformation when subjected to external impact, thereby better enhancing the cushioning performance of the skirt 6 and providing more effective protection for the speaker.

[0023] Furthermore, the intersection of two adjacent surfaces on side shell 1 features an arc-shaped structure. Specifically, when the speaker falls to the ground, the impact force is transmitted along the shell surface. The arc-shaped structure, utilizing its smooth transition geometry, alters the direction of impact force transmission, distributing stress that would otherwise concentrate at the corners evenly over a larger area of ​​side shell 1. This effectively prevents cracks or breaks caused by excessive localized stress on side shell 1 due to stress concentration, protecting not only the integrity of the protective shell structure itself but also providing more durable and reliable protection for the internal speaker.

[0024] like Figure 2As shown, the bottom of the side shell 1 is provided with an anti-slip pad 9. Specifically, the anti-slip pad 9 greatly increases the friction between the side shell 1 and the placement surface, making the speaker more stable when placed.

[0025] like Figure 3 As shown, the metal bracket 4 has multiple through holes 10. Specifically, the through holes 10 are filled with molten material during the injection molding of the mounting ring 3 to form a columnar connection structure, which increases the mechanical interlocking strength between the metal bracket 4 and the mounting ring 3, reduces the risk of delamination of the connection surface between the metal bracket 4 and the mounting ring 3 when subjected to impact, and makes the metal ring more stable inside the mounting ring 3.

[0026] In practical use, since the connecting strap 2 is made of silicone and is deformable, the user only needs to gently open the connecting strap 2 to smoothly insert the speaker into the mounting ring 3 in the middle of the side shell 1. The mounting ring 3 fits tightly against the speaker, and the embedded metal bracket 4 further enhances the strength and stability, ensuring that the speaker is securely fixed inside the shell. When the drop-proof shell is placed on a desktop, tabletop, or other surface, the two triangular side shells 1 provide a stable support surface, effectively preventing the speaker from rolling due to slight touches or external interference. In the event of an accidental drop, the silicone shell, with its high elasticity and flexibility, absorbs some of the impact force through its own compression and deformation. The hollowed-out buffer hole 5 on the side shell 1, located outside the mounting ring 3, further enhances the deformation capability of the side shell 1. Upon impact, the silicone material around the buffer hole 5 deforms fully, converting the impact force into its own elastic potential energy, thus providing a buffering effect and reducing the impact on the speaker. In the event of a side fall, the skirt 6 extending outward from the end of the side shell 1 away from the connecting strap 2 will contact the ground first. The skirt 6, through its own deformation, buffers the lateral impact force, preventing the impact force from acting directly on the speaker. By providing comprehensive drop protection for the speaker, the possibility of damage to the speaker casing, internal circuitry, and other components is reduced, providing reliable protection for the user's audio equipment.

[0027] The present invention has been further described above with reference to specific embodiments. However, it should be understood that the specific description herein should not be construed as limiting the substance and scope of the present invention. Various modifications made by those skilled in the art to the above embodiments after reading this specification are all within the scope of protection of the present invention.
