Abstract
Description
Technical Field
[0001] This utility model relates to the field of mobile phone accessories technology, specifically a heat dissipation structure for a silicone mobile phone protective case. Background Technology
[0002] Traditional phone cases are effective at protecting phones from impacts and scratches, but they fall short in terms of heat dissipation. Most phone cases feature a full-coverage design, which, while providing effective protection, also hinders heat dissipation. This is especially problematic during demanding tasks such as gaming, video playback, or high-speed data transfer, as the inability to dissipate heat quickly leads to increased phone temperature and impacts performance stability.
[0003] To address this issue, some phone cases with heat dissipation functions have emerged on the market. These cases typically employ a perforated design to increase the contact area between the phone and the outside air, promoting heat dissipation. However, existing perforated heat dissipation designs often have only a few small holes on the back of the phone, resulting in limited heat dissipation area and failing to effectively meet the demands of high heat dissipation. Furthermore, these heat dissipation cases require additional tools or steps for installation or removal, increasing the difficulty for users. Summary of the Invention
[0004] In order to overcome the shortcomings of existing technical solutions, this utility model provides a heat dissipation structure for a silicone mobile phone protective case, which can effectively solve the problem of integrating heat dissipation and support in mobile phone protective cases as mentioned in the background art.
[0005] The technical solution adopted by this utility model to solve its technical problem is: a silicone mobile phone protective case heat dissipation structure, including a silicone case body and a rotatable support on the back. The back of the silicone case body is provided with a hollow groove that matches the outline of the support. The support is embedded in the edge of the hollow groove through a rotating shaft. When the support is stored, it completely covers the hollow groove. When the support is rotated and unfolded, at least 60% of the hollow groove is exposed to form a heat dissipation channel.
[0006] Furthermore, the inner wall of the hollowed-out groove is provided with guide ribs, which are embedded inside the silicone sleeve body and are flush with the height of the silicone sleeve body.
[0007] Furthermore, the edge of the hollowed-out groove is provided with a magnetic component, and the corresponding position of the bracket is provided with an adsorption iron sheet to achieve magnetic fixation of the bracket in the stored state.
[0008] Furthermore, the rotating shaft is a damped rotating shaft with a rotational torque of 0.1-0.3 N·m.
[0009] Furthermore, the back of the bracket is provided with a protrusion that matches the shape and size of the hole in the hollow groove.
[0010] Furthermore, a notch is provided below the hollowed-out groove of the silicone sleeve body.
[0011] Furthermore, the lower end of the bracket is provided with an anti-slip pad.
[0012] Compared with existing technologies, the beneficial effects of this invention are: when the bracket is rotated and unfolded, at least 60% of the hollowed-out area is exposed, forming a heat dissipation channel. This allows the heat generated by the phone to dissipate more quickly. Although silicone material itself has a certain degree of flexibility and protection, its thermal conductivity is relatively average. Through this large-area hollowed-out design, air can circulate more freely on the back of the phone, carrying away heat.
[0013] The rotatable back stand not only supports the phone but also integrates with a heat dissipation structure. When the user needs to use the stand, simply rotate it to unfold, simultaneously providing support and cooling for the phone.
[0014] By integrating heat dissipation and stand functions into one phone case, it achieves a one-stop solution for phone protection, heat dissipation, and support. Attached Figure Description

[0020] The embodiments of this disclosure will now be described in detail with reference to the accompanying drawings.
[0021] The following specific examples illustrate the implementation of this disclosure. Those skilled in the art can easily understand other advantages and effects of this disclosure from the content disclosed in this specification. Obviously, the described embodiments are only a part of the embodiments of this disclosure, and not all of them. This disclosure can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this disclosure. It should be noted that, in the absence of conflict, the following embodiments and features in the embodiments can be combined with each other. Based on the embodiments in this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure. Example
[0022] like Figure 1-3 As shown, this utility model provides a heat dissipation structure for a silicone mobile phone protective case, including a silicone case body 1 and a rotatable support 2 on the back. The back of the silicone case body 1 is provided with a hollow groove 3 that matches the contour of the support 2. The support 2 is embedded in the edge of the hollow groove 3 through a pivot 4. When the support 2 is stored, it completely covers the hollow groove 3. When the support 2 is rotated and unfolded, at least 60% of the area of the hollow groove 3 is exposed to form a heat dissipation channel.
[0023] When the bracket 2 is rotated and unfolded, at least 60% of the area of the hollowed-out groove 3 is exposed, forming a heat dissipation channel that is in direct contact with the outside air. This increases the air circulation area on the back of the phone, which helps to quickly dissipate heat and reduce the phone's temperature.
[0024] When the stand 2 is stowed, its outline perfectly matches the cutout 3, forming a seamless cover. This ensures that the silicone case body 1 still provides complete protection when the stand 2 is stowed, preventing dust, moisture, and other contaminants from penetrating the back of the phone.
[0025] The rotating bracket 2 can not only be used for heat dissipation, but also as a phone stand 2, supporting landscape and portrait switching to meet the user's needs in different scenarios.
[0026] The bracket 2 is embedded in the edge of the hollow groove 3 via the rotating shaft 4, ensuring smoothness and stability during rotation. The design of the rotating shaft 4 should take into account wear resistance and corrosion resistance to extend the product's service life.
[0027] See Figure 1 The inner wall of the hollow groove 3 is provided with guide ribs 5, which are embedded in the inner side of the silicone sleeve body 1 and are flush with the height of the silicone sleeve body 1.
[0028] The heat guide rib 5 is in close contact with the back of the phone. The heat guide rib 5 guides the heat of the phone to the hollow groove 3, so that the heat generated by the phone can be dissipated to the surrounding environment more quickly through the hollow groove 3, which helps to reduce the temperature of the phone and prevent performance degradation or damage caused by overheating.
[0029] The guide rib 5 acts as a reinforcing rib to a certain extent, increasing the structural strength of the phone case. This helps prevent the phone case from deforming or being damaged when subjected to external impact, protecting the phone from damage.
[0030] See Figure 2 The hollow groove 3 has a magnetic component 6 on its edge, and the bracket 2 has an adsorption iron piece 7 at the corresponding position to achieve magnetic fixation of the bracket 2 in the storage state.
[0031] The magnetic component 6 and the iron sheet work together to ensure that the bracket 2 is precisely aligned with the edge of the hollow groove 3 when it is in the storage state, preventing the bracket 2 from accidentally unfolding due to shaking or external force.
[0032] The magnetic fixation prevents the bracket 2 from automatically unfolding due to pressure or friction in environments such as backpacks and pockets, reducing the risk of damage to the protective case or phone drop caused by the bracket 2 accidentally opening.
[0033] The magnetic fixation ensures that the bracket 2 fits tightly against the edge of the hollowed-out groove 3 when stored, preventing dust and moisture from entering the back of the phone through gaps, while maintaining the clean appearance of the protective case. The magnetic fixation reduces mechanical friction between the bracket 2 and the edge of the hollowed-out groove 3, reducing the risk of wear or loosening due to long-term use and extending the overall lifespan of the protective case.
[0034] Among them, the rotating shaft 4 is a damping rotating shaft with a rotational torque of 0.1-0.3 N·m.
[0035] The damping shaft 4 generates friction through the compression between the washers, ensuring the stability of the bracket 2 during rotation and preventing it from easily wobbling or changing angle due to external forces. The design with a rotational torque of 0.1-0.3 N·m ensures both smooth rotation of the bracket 2 and sufficient resistance, allowing it to stop precisely at the desired position for accurate positioning.
[0036] See Figure 3 The back of the bracket 2 is provided with a protrusion 8, which matches the shape and size of the hole in the hollow groove 3.
[0037] The shape and size of the protrusion 8 match the hole, so that the bracket 2 can be precisely aligned when it is embedded in the hollow groove 3, and is fixed by physical limiting to avoid displacement or shaking due to external force.
[0038] See Figure 2 The silicone sleeve body 1 has a notch 10 below the hollow groove 3.
[0039] The silicone material itself is soft and conforms to the phone, so users may find it difficult to pry out the stand 2 by hand due to insufficient friction or difficulty in applying force with their fingers. The notch 10 design provides users with a clear point of application, allowing them to easily pry out the stand 2 from its stored state by inserting their fingernail or fingertip into the notch 10.
[0040] See Figure 3 The lower end of the bracket 2 is provided with an anti-slip pad 9.
[0041] During the use of the bracket 2, whether it is placed on a table, the ground or other flat surface, the anti-slip mat 9 can effectively prevent the bracket 2 from sliding or shifting due to external force or its own unstable center of gravity by increasing the friction with the contact surface, ensuring that the bracket 2 always stays in the predetermined position and provides stable support for the items placed on the bracket 2.
