Description

Technical Field

[0001] This utility model relates to the field of mobile phone case technology, and in particular to a shock-resistant mobile phone back cover with a cushioning function. Background Technology

[0002] Because mobile phones are prone to accidental drops in daily use and in vehicles, resulting in damage to the body and screen, and consumers have increasingly stringent requirements for protective performance, drop-resistant mobile phone back covers have been developed. These covers absorb and disperse impact through material deformation and structural cushioning, providing multiple layers of protection when the phone is dropped, reducing the risk of damage to the body and internal components, and protecting the device's safety.

[0003] A search revealed Chinese patent publication number CN212543847U, which discloses a drop-proof phone case. The case includes a rim protecting the phone's perimeter and a back panel protecting the back of the phone. The rim forms a phone mounting cavity at the edge of the back panel. Each of the four corners of the rim protrudes away from its center, forming buffer protrusions. Each buffer protrusion has a vent hole communicating with the phone mounting cavity. This drop-proof phone case, with the rim and back panel working together, protects the phone inside the mounting cavity. When the phone is dropped, the buffer protrusions at the four corners of the rim are the first to be impacted, providing a cushioning effect. Then, the gas inside the phone mounting cavity is released through the vent holes, further reducing the impact force on the phone and effectively protecting it.

[0004] The aforementioned patent has the following shortcomings: Since the back panel and outer frame of the existing device are integrated, and the outer frame is made of hard plastic, the outer frame needs to be forcibly pried open to enlarge the opening before the phone can be inserted when putting on the case, which significantly increases the difficulty of operation. It not only consumes a lot of effort, but also easily causes cracks or breaks in the outer frame due to improper force.

[0005] Therefore, a shock-resistant mobile phone back cover with cushioning function is proposed. Utility Model Content

[0006] In view of this, the present invention aims to provide a shock-resistant mobile phone back cover with a cushioning function to solve or alleviate the technical problems existing in the prior art, and at least provide a beneficial option.

[0007] The technical solution of this utility model embodiment is implemented as follows: a shock-resistant mobile phone back cover with a cushioning function, including a plastic outer frame, and further including:

[0008] A buffer strip is fixed at the four corners of the outer side of the plastic frame. The outer side of the buffer strip is fitted with a silicone sleeve that connects to the plastic frame. A button sleeve is fixed to the side of the plastic frame.

[0009] A backplate is detachably mounted on one side of a plastic outer frame, and a lens frame is fixed to the top of one side of the backplate.

[0010] The loading and unloading structure is set between the plastic outer frame and the back panel. The loading and unloading structure includes a buckle block fixed to the top of one side of the back panel, a buckle groove is opened at the top of the inside of the plastic outer frame, and a connecting component is provided at the bottom of one side of the back panel.

[0011] A support structure for supporting the back panel is provided at the bottom end of one side of the back panel;

[0012] A shielding structure for physically obscuring the lens frame is located at the top of one side of the back panel.

[0013] In some embodiments: the connecting assembly includes a connecting post fixed to the bottom of the inside of the plastic frame, a buckle fixed to the bottom of one side of the back plate, and a retaining ring fixed to the side of the inside of the plastic frame away from the back plate.

[0014] In some embodiments: the side cross-section of the buckle has a "C" shape, and the buckle and the connecting post form a rotating structure.

[0015] In some embodiments: the fastener and the fastener groove form an engaging structure, and the fasteners are symmetrically distributed on the vertical center line of the back panel.

[0016] In some embodiments: the shielding structure includes a rotating seat fixed to the top of one side of the back plate, a baffle plate rotatably connected to the outer side of the rotating seat, a friction strip fixed to one side of the baffle plate, a slot opened on one side inside the baffle plate, a locking block fixed to the bottom of one side of the lens frame, and a limiting plate fixed to the side of the lens frame.

[0017] In some embodiments: the slot and the block form an engaging structure, and the friction strips are arranged at equal intervals on one side of the baffle.

[0018] In some embodiments: the support structure includes a mounting base fixed inside one side of the back plate, a rotating sleeve rotatably connected to the outer side of the mounting base, a connecting ring rotatably connected to the top end of one side of the rotating sleeve, and a support ring rotatably connected to the bottom end of one side of the connecting ring.

[0019] In some embodiments: when the connecting ring and the support ring are folded, they are both sleeved on the outside of the rotating sleeve, and the cross-sections of the connecting ring, the support ring and the rotating sleeve are all octagonal.

[0020] The present invention has the following advantages due to the adoption of the above technical solution:

[0021] 1. A shock-resistant mobile phone back cover with a cushioning function, which achieves the back cover installation and removal function by connecting the buckle to the connecting post, and then pushing the back panel to insert the buckle block into the buckle groove, thereby fixing the back panel to the plastic outer frame. This can avoid material damage caused by forced deformation of the outer frame, extend the service life of the back cover, reduce friction and collision between the back cover and the corners of the mobile phone during the installation process, and allow the back panel to be replaced to install back panels with different patterns to change the appearance style of the mobile phone.

[0022] 2. A shock-resistant mobile phone back cover with a cushioning function, which pushes a baffle to rotate around a rotating base so that the baffle covers the outside of the lens frame and physically blocks the lens. The rotation range of the baffle can be limited by a limiting plate, thereby realizing the lens blocking function of this device. When the lens is not in use, the lens area can be physically blocked to prevent dust, water stains or accidental scratches from adhering to the lens during daily use, and also to prevent malicious programs from starting the lens to shoot in the background without authorization, thus eliminating the risk of privacy leakage.

[0023] 3. A shock-resistant mobile phone back cover with a cushioning function, which supports the mobile phone by adjusting the position of the support ring so that the support ring contacts the table. The angle of the support ring is changed by adjusting the angle of the connecting ring, thereby realizing the table support function of the device, allowing the mobile phone to stand stably on the table without the need for an additional stand, and the support angle can be flexibly adjusted to adapt to different usage scenarios.

Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0036] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0037] Example 1:

[0038] like Figures 1 to 6 As shown, a shock-resistant mobile phone back cover with a cushioning function includes a plastic outer frame 1, and also includes:

[0039] The buffer strip 7 is fixed at the four corners of the outer side of the plastic frame 1. The outer side of the buffer strip 7 is fitted with a silicone sleeve 3 that is connected to the plastic frame 1. A button sleeve 6 is fixed to the side of the plastic frame 1.

[0040] The back panel 2 is detachably installed on one side of the plastic outer frame 1, and the lens frame 5 is fixed to the top of one side of the back panel 2.

[0041] The loading and unloading structure 4 is set between the plastic outer frame 1 and the back plate 2. The loading and unloading structure 4 includes a buckle 402 fixed to the top of one side of the back plate 2, a buckle groove 401 is opened at the top of the inside of the plastic outer frame 1, and a connecting component is provided at the bottom of one side of the back plate 2.

[0042] The support structure 9 for supporting the back plate 2 is provided at the bottom end of one side of the back plate 2.

[0043] The shielding structure 8, which is used to physically block the lens frame 5, is located at the top of one side of the back plate 2.

[0044] In this embodiment, the phone is first placed inside the plastic frame 1, and the retaining ring 405 is used to hold the edge of the phone screen to prevent the phone from shifting inside the plastic frame 1. Then, the back plate 2 is installed on one side of the plastic frame 1 through the mounting and disassembly structure 4, completing the assembly of the plastic frame 1 and the back plate 2. During daily use, the silicone sleeve 3 can absorb the impact force when the phone is accidentally dropped, and the buffer strip 7 further enhances the buffering effect by twisting and deforming under force, which reduces the risk of the phone being damaged by collision to a certain extent. The button sleeve 6 on the side of the plastic frame 1 can protect the phone buttons while ensuring the smooth operation of the buttons. The lens frame 5 at the top of one side of the plastic frame 1 can provide basic protection for the phone lens and prevent the lens from being scratched by daily use to a certain extent.

[0045] like Figures 1 to 4 As shown, the connecting assembly includes a connecting post 404 fixed to the bottom of the inside of the plastic outer frame 1, a buckle 403 fixed to the bottom of one side of the back plate 2, a retaining ring 405 fixed to the side of the inside of the plastic outer frame 1 away from the back plate 2, the side cross-section of the buckle 403 is C-shaped, the buckle 403 and the connecting post 404 form a rotating structure, the buckle block 402 and the buckle groove 401 form a locking structure, and the buckle block 402 is symmetrically distributed on the vertical center line of the back plate 2.

[0046] In this embodiment, when the back plate 2 needs to be installed, the buckle 403 is connected to the connecting post 404, causing the buckle 403 to rotate around the connecting post 404. At the same time, the back plate 2 is moved closer to the plastic outer frame 1. Then, the buckle block 402 is aligned with the buckle groove 401, and the back plate 2 is pushed so that the buckle block 402 and the buckle groove 401 form a locking structure, thereby completing the fixed installation of the back plate 2 and ensuring the stability of the connection between the back plate 2 and the plastic outer frame 1 to a certain extent. When the back plate 2 needs to be disassembled, the top of the back plate 2 is pushed in the opposite direction to disengage the buckle block 402 from the buckle groove 401. At the same time, the buckle 403 is rotated around the connecting post 404, causing the back plate 2 to separate from the plastic outer frame 1, thereby realizing the convenient disassembly of the back plate 2.

[0047] Example 2:

[0048] A shock-resistant mobile phone back cover with cushioning function. This embodiment is based on embodiment 1 with the following improvements, such as... Figure 5 As shown, the shielding structure 8 includes a rotating seat 804 fixed to the top of one side of the back plate 2. A baffle 801 is rotatably connected to the outside of the rotating seat 804. A friction strip 802 is fixed to one side of the baffle 801. A slot 803 is opened on one side inside the baffle 801. A locking block 805 is fixed to the bottom of one side of the lens frame 5. A limit plate 806 is fixed to the side of the lens frame 5. The slot 803 and the locking block 805 form a locking structure. The friction strips 802 are arranged at equal intervals on one side of the baffle 801.

[0049] In this embodiment, when the mobile phone lens is not needed, the baffle 801 is pushed to rotate around the rotating base 804, causing the baffle 801 to move towards the lens frame 5. Then, the slot 803 aligns with the locking block 805, and the slot 803 engages with the locking block 805, allowing the baffle 801 to cover the outside of the lens frame 5 and physically block the lens. The limiting plate 806 can limit the rotation range of the baffle 801, which to some extent avoids the baffle 801 shifting and causing incomplete blocking. When the lens needs to be used, the baffle 801 is pushed in the opposite direction, causing the slot 803 to disengage from the locking block 805, and then the baffle 801 is rotated around the rotating base 804 to a suitable position, thereby removing the blocking of the lens and ensuring the normal use of the lens to some extent.

[0050] like Figure 6 As shown, the support structure 9 includes a mounting base 902 fixed inside one side of the back plate 2. A rotating sleeve 901 is rotatably connected to the outer side of the mounting base 902. A connecting ring 904 is rotatably connected to the top of one side of the rotating sleeve 901. A support ring 903 is rotatably connected to the bottom of one side of the connecting ring 904. When the connecting ring 904 and the support ring 903 are folded, they are both sleeved on the outer side of the rotating sleeve 901. The cross-sections of the connecting ring 904, the support ring 903 and the rotating sleeve 901 are all octagonal.

[0051] In this embodiment, when the phone needs to be placed on a table for use, the angle of the connecting ring 904 is adjusted by pushing the connecting ring 904 and the support ring 903 away from the outside of the rotating sleeve 901. Then, the support ring 903 is rotated around the connecting ring 904 to adjust its position. When the phone is placed on the table, the support ring 903 contacts the table and supports the phone. By adjusting the angle of the connecting ring 904, the angle of phone support is changed. When the support function is not needed, the connecting ring 904 and the support ring 903 are rotated in the opposite direction and fitted onto the outside of the rotating sleeve 901, which reduces the space occupied by the support structure 9 to a certain extent.

[0052] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
