[0039] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0040] At present, with the increasing demand of users for the refined appearance of electronic devices such as smartphones, smartphones are developing in the direction of becoming lighter and thinner, resulting in smaller and smaller internal space of smartphones, making it easier for the vibrating airflow generated by electronic devices to cause shell vibration of the back shell of the electronic device.

[0041] In addition, the increasingly smaller internal space also leads to mutual interference between electronic devices that are close to each other. For example, the vibrating airflow generated by the drive motor and the sound-generating device may resonate, causing the housing of the electronic device to vibrate.

[0042] In order to solve the above problems, the embodiments of the present disclosure provide a bracket assembly, a shell assembly and an electronic device, wherein the bracket assembly includes a bracket body and an airflow guiding structure, wherein the bracket body includes a first area for mounting a first vibrating device, the airflow guiding structure is disposed on the bracket body and communicated with the first area, and the airflow guiding structure is used to guide the flow of the vibrating airflow generated by the first vibrating device. In the present disclosure, the airflow guiding structure is communicated with the first area on the bracket body where the first vibrating device is mounted, and the airflow generated by the vibration of the first vibrating device can be conducted along the airflow guiding structure and gradually weakened in the airflow guiding structure, so as to reduce or avoid the influence of the vibrating airflow on the sound and grip of the electronic device, thereby improving the user experience.

[0043] According to an exemplary embodiment of the present disclosure, Figures 1 to 3 As shown, the embodiment of the present disclosure provides a bracket assembly 20, which is applied to electronic devices, such as smart phones, laptops, vehicle-mounted devices, smart watches, etc. The bracket assembly 20 is arranged in the electronic device, which can provide support for the display screen, rear shell 200 and other structures of the electronic device.

[0044] like Figure 1 and Figure 2 As shown, in the embodiment of the present disclosure, the bracket assembly 20 includes a bracket body 21. The material of the bracket body 21 includes an alloy material, such as an aluminum alloy. The material of the bracket body 21 can also be a non-metallic material, such as carbon fiber. In the embodiment of the present disclosure, the bracket assembly 20 can provide support for the rear shell 200 of the electronic device as an example for explanation, that is, the support assembly can be a bracket for the rear shell 200 in the electronic device.

[0045] Among them, continue to refer to Figure 2 The support body 21 is provided with a first area 211, and the first area 211 is used to install the first vibrating device 30. In the embodiment of the present disclosure, a first area 211 in the form of a through hole is exemplarily shown, and the first vibrating device 30 can be installed through the support body 21. In one example, referring to Figure 2 and Figure 3 The first vibration device 30 can be a rear camera of a mobile phone. The first area 211 includes a first through hole 211a, a second through hole 211b and a third through hole 211c. The first through hole 211a can be used to avoid a main camera lens, the second through hole 211b can be used to avoid a telephoto lens, and the third through hole 211c can be used to avoid a macro lens, but the present invention is not limited thereto.

[0046] like Figure 2 As shown, in the embodiment of the present disclosure, the bracket assembly 20 further includes an airflow guiding structure 22, and the airflow guiding structure 22 is disposed on the bracket body 21. The airflow guiding structure 22 is connected to the first area 211 on the bracket body 21. When the first vibration device 30 generates a vibrating airflow, the vibrating airflow can be conducted from the first area 211 to the airflow guiding structure 22, and gradually weakened or offset in the airflow guiding structure 22, thereby weakening or eliminating the influence of the vibrating airflow on other structures (such as the earpiece and the back shell 200 of the electronic device), thereby achieving the effect of reducing or avoiding the external projection of the electronic device, and being able to reduce or avoid the shell vibration of the electronic device.

[0047] In one example, the airflow guiding structure 22 may be a pipe, and the side wall of the pipe is provided with an opening, and the opening may allow the inner cavity of the pipe to communicate with the first area 211. In another example, the airflow guiding structure 22 may be a slot body, and the side wall of the slot body has a structure extending outward, so that the slot body is in communication with the first area 211.

[0048] In the embodiment of the present disclosure, the airflow guiding structure is connected to the first area on the bracket body where the first vibration device is installed. The airflow generated by the vibration of the first vibration device can be conducted along the airflow guiding structure and gradually weakened in the airflow guiding structure to reduce or avoid the impact of the vibrating airflow on the sound and grip of the electronic device, thereby improving the user experience.

[0049] In an exemplary embodiment, Figures 1 to 3 As shown, an embodiment of the present disclosure provides a bracket assembly 20, which includes a bracket body 21 and an airflow guiding structure 22. The bracket body 21 includes a first area 211 for installing a first vibration device 30. The airflow guiding structure 22 is arranged on the bracket body 21 and is connected to the first area 211. The airflow guiding structure 22 is used to guide the flow of vibrating airflow generated by the first vibration device 30.

[0050] In one example, reference Figure 2 The airflow guiding structure 22 may be a first groove provided on the bracket body 21, and the first groove is formed by the surface of the bracket body 21 along the thickness direction of the bracket body 21 ( Figure 1 The first groove is formed by a depression (in the z direction as shown in FIG. 1 ), and the side wall of the first groove can be connected to the first area 211, that is, the vibrating airflow in the first area 211 can enter the first groove through the side wall of the first groove, and offset and reduce each other in the first groove. In the assembled state, the side of the bracket body 21 provided with the first groove can be fitted with other structures (such as the rear shell of the electronic device), so that the first groove forms an airflow guide channel.

[0051] Among them, reference Figure 2 , at different positions of the bracket body 21, the first groove is along the thickness direction of the bracket body 21 ( Figure 1 The depth of the first groove is different from the depth of the depression in the z direction (as shown in FIG. 1 ). The depth of the first groove can be adaptively set according to the simulation effect, so that the first groove can accurately weaken or eliminate the vibrating airflow generated by the first vibrating device 30. In some optional embodiments, the depression depth of the first groove can also be adaptively set according to the shape of other devices connected to the bracket body 21. For example, a slope, a bump or the like can be set in the first groove so that the first groove has different depression depths, thereby compensating for the aperture of the airflow guide channel.

[0052] refer to Figure 2 In the airflow guiding structure 22 provided in the embodiment of the present disclosure, the vibrating airflow generated by the first vibrating device 30 can be along Figure 2 The flow is counterclockwise in the direction indicated by arrows a and b.

[0053] refer to Figure 2 The first groove may have a depth of 0.1 mm to 0.5 mm. For example, the first groove may have a depth of 0.1 mm, 0.15 mm, 0.3 mm, 0.5 mm, etc.

[0054] In another example (not shown in the drawings), the airflow guiding structure may include a first protrusion disposed on the bracket body, and the first protrusion is disposed around the first area. It is understood that the side of the bracket body provided with the first protrusion can be attached to other devices, so that the first protrusion can enclose the airflow guiding channel. In this example, the first protrusion can be formed by the surface of the bracket body along the thickness direction ( Figure 1The first protrusion is formed by protruding in the z direction (as shown in the figure), and the electronic components arranged on the bracket body can also serve as the first protrusion, such as capacitors. In this example, there can be only one first protrusion on the bracket body surrounding the first area, so that the inner area of ​​the first protrusion forms an airflow guiding channel. In this example, a plurality of first annular protrusions can also be arranged on the bracket body, and the area between adjacent first protrusions forms an airflow guiding structure.

[0055] In another example (not shown in the drawings), the airflow guiding structure may include a first groove and a first protrusion disposed on the bracket body, the first groove and the first protrusion both surround the first area, wherein the first protrusion is disposed outside the first groove. In this example, the first groove may be formed by the surface of the bracket body along the thickness direction of the bracket body ( Figure 1 The first protrusion may be formed by a depression in the z direction (as shown in FIG. 1 ), the first protrusion may be formed by a square protrusion along the thickness of the surface of the bracket body, and the first protrusion may also be formed by an electronic component arranged on the bracket body.

[0056] In an exemplary embodiment, Figures 1 to 3 As shown, an embodiment of the present disclosure provides a bracket assembly 20, which includes a bracket body 21 and an airflow guiding structure 22. The bracket body 21 includes a first area 211 for installing a first vibration device 30. The airflow guiding structure 22 is arranged on the bracket body 21 and is connected to the first area 211. The airflow guiding structure 22 is used to guide the flow of vibrating airflow generated by the first vibration device 30.

[0057] The bracket assembly 20 provided in this embodiment may include various structures, devices, etc. provided in any of the above embodiments.

[0058] In this embodiment, Figure 2 and Figure 4 As shown, the bracket body 21 further includes a second area 212 for mounting the second vibrating device 40 . The second area 212 is provided with a first partition 2121 . The first partition 2121 can partition the second area 212 into two independent sub-areas 2122 .

[0059] refer to Figure 4 The bracket body is provided with a second groove, which corresponds to the sub-region 2122. The second groove can be formed by the surface of the bracket body 21 being recessed along the thickness direction of the bracket body 21. In the assembled state, the sub-region 2122 can be enclosed with the second vibrating device 40 in the electronic device to form an airflow guiding channel. In one example, reference Figure 4 , the depression depth of the second groove is greater than or equal to 0.5 mm.

[0060] In an optional embodiment, a second protrusion is provided on the bracket body 21, and the second protrusion surrounds the sub-region 2122. The surface of the bracket body 21 is along the thickness direction of the bracket body 21 ( Figure 4 The z direction (as shown in FIG. 4 ) protrudes to form a second protrusion.

[0061] refer to Figure 4 and Figure 5 The second vibration device 40 may be a handset, which is an accessory for transmitting sound in communication tools such as telephones, intercoms, and mobile phones. The handset can generate vibrations through its structure to drive air vibrations, thereby producing sound. Figure 4 and Figure 5 The earpiece has two sound outlet holes 41 and a partition bone position 42 located between the two sound outlet holes 41. In the assembled state, the earpiece can be buckled with the bracket body 21. The two sound outlet holes 41 of the earpiece correspond to the two sub-areas 2122 on the bracket body 21 respectively. The partition bone position 42 of the earpiece abuts against the first partition part 2121 of the bracket body 21. It can be determined that the two sub-areas 2122 and the earpiece are buckled to form two airflow guiding channels. The first partition part 2121 and the partition bone position 42 separate the two airflow guiding channels so as not to interfere with each other, so that the sound emitted by the earpiece can flow to the rear cavity in the two sub-areas 2122 in an orderly manner. On the one hand, it can reduce the vibration of the housing of the electronic device caused by the resonance of the two sub-areas 2122. On the other hand, it can also avoid the irregular airflow of the sound outlet hole causing noise, thereby achieving the effect of regular pronunciation and improving the sound quality.

[0062] Among them, reference Figure 4 A first filler is disposed on one side of the first partition 2121 away from the bracket body 21. In one example, the first filler may be double-sided foam. The first filler is located between the bracket body 21 and the second vibrating device 40 (such as an earpiece) to enhance the sealing performance of the first partition 2121 and the partition bone position 42 to prevent the airflows in the two sub-areas 2122 from interfering with each other.

[0063] In some embodiments, Figure 2 As shown, the bracket assembly 20 has a second partition 213, and the second partition 213 is located between the first area 211 and the second area 212. The second partition 213 is used to separate the first area 211 and the second area 212 to avoid interference between the first vibration device 30 and the second vibration device 40. For example, it can avoid resonance of the vibration airflow of the first vibration device 30 and the second vibration device 40, resulting in obvious shell vibration of the electronic device. For another example, it can also avoid that the vibration airflow generated by the first vibration device 30 affects the sound quality of the second vibration device 40 (earpiece).

[0064] In one example, reference Figure 2The second partition 213 is in a strip shape, and the extension direction of the strip is perpendicular to the arrangement direction of the first area 211 and the second area 212 .

[0065] In another example, refer to Figure 2 A second filler 23 is provided on one side of the second partition 213 away from the bracket body 21. The second filler 23 may be, for example, double-sided foam, which can connect the bracket body 21 and the rear shell 200 or the housing body 10 (described in detail later) of the electronic device together to reduce the vibration of the rear shell 200 of the electronic device caused by the vibration airflow.
