Abstract
Description
Technical Field
[0001] This utility model relates to the field of mobile phone casing technology, specifically a mobile phone casing structure with a heat dissipation channel. Background Technology
[0002] As smartphone performance improves, chip heat generation intensifies under high load scenarios. Overheating can lead to lag, reduced battery life, and even hardware damage. Traditional phone cases often focus on protection, using closed or semi-closed designs to hinder heat dissipation.
[0003] Existing technologies lack scratch protection for the camera lens. Since the camera lens is directly exposed, it is easily scratched by contact with hard objects such as keys during daily use. These scratches scatter the light entering the lens, causing blurry images, glare, and light spots. Furthermore, scratches may accumulate dust and dirt, which are difficult to clean completely. Long-term adhesion will accelerate lens wear and may even seep into the camera and damage the photosensitive element. Therefore, we propose a mobile phone casing structure with a heat dissipation channel. Utility Model Content
[0004] The purpose of this invention is to provide a mobile phone casing structure with a heat dissipation channel to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a mobile phone casing structure with a heat dissipation channel, including a casing, a camera port opened on the casing, and further comprising:
[0006] A scratch-resistant component, comprising a slide rail connected to a housing, a sliding block slidably connected to the slide rail, and a baffle connected to the sliding block;
[0007] A locking assembly includes a fixed shaft connected to a baffle, a locking member connected to the fixed shaft, a rotating shaft rotatably connected to the housing, a limiting member connected to the rotating shaft, a protrusion provided on the side of the limiting member near the rotating shaft, and grooves provided on both the upper and lower sides of the locking member, with the outer side of the protrusion fitting against the groove.
[0008] Furthermore, a spring-loaded assembly is provided on the side of the housing near the limiting member. The spring-loaded assembly includes an extension plate connected to the housing, and a spring is connected between the extension plate and the limiting member.
[0009] The above technical solution is adopted: by setting a rebound component, the limiting parts that are squeezed to both sides can automatically spring back to their original position by the elastic force of the spring, so that the protrusion is locked in the groove.
[0010] Furthermore, the housing is provided with an auxiliary component, which includes a suction cup connected to the housing, and a connector is connected to the suction cup.
[0011] The above technical solution allows for positioning of a mobile phone by attaching it to an object using a suction cup when both hands are inconvenient.
[0012] Furthermore, the inner wall of the housing is provided with a drop protection component, which includes protrusions distributed at the four corners of the inner wall of the housing, and the protrusions are made of elastic material.
[0013] The above technical solution is adopted: by setting convex points, part of the impact force is absorbed by compressing the gaps, and the concentrated impact force is distributed to multiple support points, thereby reducing the stress intensity at a single point.
[0014] Furthermore, a micro airbag is provided on the inner wall of the housing near the protrusion.
[0015] The above technical solution involves setting up a micro airbag. When falling, the airbag generates a buffering force by compressing gas, and the compressibility of the gas prolongs the impact time.
[0016] Furthermore, the housing is provided with heat dissipation channels, and the slide rail is provided with through holes.
[0017] The above technical solution involves setting up heat dissipation channels to promptly release the heat generated during phone operation, and the through-hole design reduces the weight of the sliding rail, thereby reducing the overall weight of the phone case.
[0018] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0019] In this invention, by setting up anti-scratch components, the lens can be directly protected from scratches by hard objects, maintaining the smoothness of the lens surface. Secondly, it can reduce the adhesion of dust and stains, reducing the difficulty of cleaning. It solves the problem that the existing technology lacks anti-scratch function at the camera lens. Since the camera lens is directly exposed, it is easy to come into contact with hard objects such as keys during daily use, resulting in scratches. These scratches will scatter the light entering the lens, causing blurry images, glare, and light spots. Moreover, scratches may accumulate dust and stains, which are difficult to clean thoroughly. Long-term adhesion will aggravate lens wear and may even seep into the camera and damage the photosensitive element. Attached Figure Description

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0033] like Figures 1-4 As shown, this utility model provides a technical solution: a mobile phone casing structure with a heat dissipation channel, including a casing 1, a camera port 2 opened on the casing 1, and further including:
[0034] The anti-scratch component 3 includes a slide rail 32 connected to the housing 1, a sliding block 33 slidably connected to the slide rail 32, and a baffle 31 connected to the sliding block 33;
[0035] Locking assembly 4 includes a fixed shaft 43 connected to the baffle 31, a locking member 42 connected to the fixed shaft 43, a rotating shaft 44 rotatably connected to the housing 1, a limiting member 41 connected to the rotating shaft 44, a protrusion 46 provided on the side of the limiting member 41 near the rotating shaft 44, and grooves 45 provided on both the upper and lower sides of the locking member 42, with the outer side of the protrusion 46 fitting against the groove 45.
[0036] Specifically, when taking photos is not required, the baffle 31 is slid along the slide rail 32 via the sliding block 33 towards the camera port 2 until it is completely blocked. Then, during the movement, the baffle 31 will drive the locking member 42 to move towards the limiting member 41. When the locking member 42 touches the limiting member 41, it will squeeze and rotate the limiting members 41 on both sides through the rotating shaft 44. Then, the protrusion 46 on the limiting member 41 will be engaged in the groove 45 to limit and fix the baffle 31.
[0037] Furthermore, such as Figure 3 As shown: The housing 1 is provided with an auxiliary component 6, which includes a suction cup 61 connected to the housing 1. A connector 62 is connected to the suction cup 61, which can be used to attach the mobile phone to an object for positioning when the hands are inconvenient.
[0038] The above solution also includes the requirement that when the limiting member 41 is squeezed to both sides, it should automatically spring back to its original position, automatically engaging the protrusion 46 within the groove 45. Figure 3 As shown: A spring-loaded assembly 5 is provided on the side of the housing 1 near the limiting member 41. The spring-loaded assembly 5 includes an extension plate 51 connected to the housing 1. A spring 52 is connected between the extension plate 51 and the limiting member 41. When the limiting member 41 is squeezed and rotated, it will squeeze the spring 52. Then, the limiting member 41 will be driven by the elastic force of the spring 52 after it is contracted to push the protrusion 46 into the groove 45 for limiting.
[0039] The above solutions also include taking appropriate drop protection measures when the phone is dropped, such as... Figure 1 As shown: The inner wall of the housing 1 is provided with a drop protection component 8, which includes protrusions 81. The protrusions 81 are distributed at the four corners of the inner wall of the housing 1. The protrusions 81 are made of elastic material. A micro airbag 82 is provided on the inner wall of the housing 1 near the protrusions 81. When the phone falls, the protrusions 81 absorb part of the impact force through the compression gap, disperse the concentrated impact force to multiple support points, reduce the force intensity of a single point, and the airbag generates buffering force by compressing gas, and uses the compressibility of gas to prolong the impact force action time.
[0040] Furthermore, such as Figure 2 As shown: The housing 1 has a heat dissipation channel 7 and the slide rail 32 has a through hole 34. By setting the heat dissipation channel 7, the heat generated during the operation of the mobile phone can be discharged in time. The setting of the through hole 34 reduces the weight of the slide rail 32, thereby reducing the overall weight of the mobile phone housing.
[0041] The working principle provided by this utility model is as follows: Figures 1-4As shown: When taking photos is not required, the baffle 31 is slid along the slide rail 32 via the sliding block 33 towards the camera port 2 until it is completely blocked. Then, during the movement of the baffle 31, the locking member 42 will move towards the limiting member 41. When the locking member 42 touches the limiting member 41, it will squeeze and rotate the limiting members 41 on both sides through the rotating shaft 44. During the process of the limiting member 41 being squeezed and rotated, the spring 52 will be squeezed simultaneously. Then, the limiting member 41 will be driven by the elastic force of the spring 52 after it is contracted to push the protrusion 46 into the groove 45 for limiting. When the phone falls, the protrusion 81 absorbs part of the impact force through the compression gap, dispersing the concentrated impact force to multiple support points and reducing the force intensity of a single point. The airbag generates buffer force by compressing gas and uses the compressibility of gas to prolong the impact force action time. The heat dissipation channel 7 is set to release the heat generated during the operation of the phone in a timely manner.
[0042] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present utility model. The implementation schemes in the above embodiments can also be further combined or replaced. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
