Description

Technical Field

[0001] The utility model relates to the technical field of mobile phone protection, and particularly to a heat dissipation device for a mobile phone cover plate. Background Technique

[0002] With the continuous progress of technology and the continuous change of consumer demands, the future mobile phone back covers will be more diversified, personalized, and continue to develop towards higher performance.

[0003] Currently, in the prior art, when a mobile phone is used for a long time or performs high-load tasks, a large amount of heat will be generated. This heat cannot be effectively dissipated, which will cause the internal temperature of the mobile phone to be too high, damage the electronic components inside the mobile phone, and thus affect the overall performance and stability of the mobile phone. In view of this, we propose a heat dissipation device for a mobile phone cover plate. Content of the Utility Model

[0004] The main purpose of the utility model is to provide a heat dissipation device for a mobile phone cover plate, which can solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the heat dissipation device for a mobile phone cover plate proposed by the utility model includes a rear cover plate. A pressing cooling device is arranged inside the rear cover plate, and an auxiliary device is also arranged inside the rear cover plate. A cooling airbag is arranged below the pressing cooling device. The cooling airbag is made of thermoplastic polyurethane and can closely fit the surface of the mobile phone to be cooled, ensuring the maximum cooling area. The pressing cooling device includes:

[0006] A moving cavity is opened inside the rear cover plate, and a first spring is fixedly connected in the moving cavity. The moving cavity is elastically connected to a limiting cylinder through the first spring;

[0007] An extrusion block is fixedly connected above the limiting cylinder, and a limiting triangular plate is fixedly connected to the outer wall of the limiting cylinder.

[0008] Preferably, a lens hole is opened on the surface of the rear cover plate, and a volume hole is opened on the outer wall of the rear cover plate. A charging hole is opened on one side of the volume hole. The lens hole is an opening designed specifically for the mobile phone camera, allowing light to pass through unobstructed to ensure that the camera can capture clear images.

[0009] Preferably, the auxiliary device includes a connecting rod. The connecting rod is fixedly connected to the outer wall of the limiting cylinder, and there are two groups of the connecting rods. The movement of the connecting rod is driven by the lifting movement of the limiting cylinder.

[0010] Preferably, a connecting plate is fixedly connected in the movable cavity, and a lifting groove is formed on the surface of the connecting plate. A limiting block is fixedly connected in the movable cavity, and the connecting rod drives the components between the connecting plate and the limiting block to move through the lifting groove.

[0011] Preferably, the connecting rod slidably penetrates through the lifting groove, and the connecting rod is slidably connected in an inclined groove formed on the surface of the pushing block. After the rear cover is clamped with the mobile phone, the extrusion block is pressed downward by the pressing force, driving the limiting cylinder to slide in the inclined groove through the connecting rod, and driving the pushing block to push toward the middle along the direction of the inclined groove.

[0012] Preferably, the pushing block is elastically connected to the movable cavity through a second spring. The pushing block presses the cooling airbag forward, and the cooling airbag fills the area of the movable cavity.

[0013] The utility model provides a heat dissipation device for a mobile phone cover plate, which has the following beneficial effects:

[0014] (1) Through the provided pressing and cooling device of the heat dissipation device for the mobile phone cover plate, after the rear cover is clamped with the mobile phone, the extrusion block is pressed downward by the pressing force. During the descending process, the limiting cylinder prevents the deviation when the first spring contracts, and the limiting triangular plate descends accordingly. The descending limiting triangular plate gradually presses the cooling airbag, and the cooling airbag fills the area of the movable cavity, which can closely fit the surface of the mobile phone to be cooled, ensuring the maximum cooling area, improving the performance stability, and protecting the internal components.

[0015] (2) Through the provided auxiliary device of the heat dissipation device for the mobile phone cover plate, the lifting movement of the connecting rod is driven by the limiting cylinder. The connecting rod drives the pushing block between the connecting plate and the limiting block to move through the lifting groove. The connecting rod slides in the inclined groove and drives the pushing block to push toward the middle along the direction of the inclined groove. The cooling airbag is jointly pressed forward by the limiting triangular plate and the pushing block, improving the cooling safety and the use effect of the rear cover.

[0027] Please refer to Figures 1-6 , this utility model proposes a heat dissipation device for a mobile phone cover plate, including a rear cover plate 1. A lens hole 101 is opened on the surface of the rear cover plate 1, and a volume hole 102 is opened on the outer wall of the rear cover plate 1. A charging hole 103 is opened on one side of the volume hole 102. The lens hole 101 is an opening specially designed for the mobile phone camera, which is used to allow light to pass through unobstructed, ensuring that the camera can capture clear images. A pressing and cooling device 2 is arranged inside the rear cover plate 1, and an auxiliary device 3 is also arranged inside the rear cover plate 1. A cooling airbag 4 is arranged below the pressing and cooling device 2. The cooling airbag 4 is made of thermoplastic polyurethane material, which can closely fit the surface of the mobile phone to be cooled, ensuring the maximum cooling area. The pressing and cooling device 2 includes an activity cavity 21.

[0028] In an embodiment of the present utility model, in order to improve performance stability and protect internal components, specifically, an activity cavity 21 is provided inside the rear cover plate 1, and a first spring 22 is fixedly connected in the activity cavity 21. The activity cavity 21 and the limiting cylinder 23 are elastically connected through the first spring 22. The setting of the limiting cylinder 23 prevents the deviation of the first spring 22 when it contracts. A pressing block 24 is fixedly connected above the limiting cylinder 23, and a limiting triangular plate 25 is fixedly connected to the outer wall of the limiting cylinder 23.

[0029] Furthermore, in order to improve the safety of cooling and the usage effect of the rear cover plate 1, specifically, the auxiliary device 3 includes a connecting rod 31. The connecting rod 31 is fixedly connected to the outer wall of the limiting cylinder 23, and there are two groups of connecting rods 31. The lifting movement of the limiting cylinder 23 drives the movement of the connecting rod 31. A connecting plate 32 is fixedly connected in the activity cavity 21, and a lifting groove 33 is provided on the surface of the connecting plate 32. A limiting block 34 is fixedly connected in the activity cavity 21. The connecting rod 31 drives the components between the connecting plate 32 and the limiting block 34 to move through the lifting groove 33. The connecting rod 31 slides through the lifting groove 33 and is slidably connected in an inclined groove 36 provided on the surface of the pushing block 35. When the rear cover plate 1 is clamped with the mobile phone, the pressing block 24 is pressed downward by the pressing force, driving the limiting cylinder 23 to slide in the inclined groove 36 through the connecting rod 31, and driving the pushing block 35 to push toward the middle along the direction of the inclined groove 36. The pushing block 35 is elastically connected to the activity cavity 21 through a second spring 37. The pushing block 35 presses the cooling airbag 4 forward, and the cooling airbag 4 fills the area of the activity cavity 21.

[0030] In the present utility model, during use, when the rear cover plate 1 is clamped with the mobile phone, the pressing block 24 is pressed downward by the pressing force. During the descending process, the limiting cylinder 23 prevents the deviation of the first spring 22 when it contracts, and the limiting triangular plate 25 descends accordingly. The descending limiting triangular plate 25 gradually presses the cooling airbag 4. The lifting movement of the limiting cylinder 23 drives the connecting rod 31. The connecting rod 31 drives the pushing block 35 between the connecting plate 32 and the limiting block 34 to move through the lifting groove 33. The connecting rod 31 slides in the inclined groove 36 and drives the pushing block 35 to push toward the middle along the direction of the inclined groove 36. The cooling airbag 4 is jointly pressed forward by the limiting triangular plate 25 and the pushing block 35. The cooling airbag 4 fills the area of the activity cavity 21 and can closely fit the surface of the mobile phone that needs to be cooled, ensuring the maximum cooling area.
