[0023] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments described herein. Rather, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0024] It should be noted that, unless otherwise specified, the technical or scientific terms used in this application should have the common meanings understood by those skilled in the art to which this application belongs.

[0025] The accompanying drawings, which are incorporated in and constitute a part of the specification, illustrate embodiments of the present application and, together with the general description of the present application given above and the detailed description of the embodiments given below, serve to explain the principles of the present application.

[0026] It should also be understood that although the present application has been described with reference to certain specific examples, those skilled in the art will be able to implement many other equivalent forms of the present application that have the features described in the claims and are therefore within the scope of protection defined thereby.

[0027] The above and other aspects, features and advantages of the present application will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.

[0028] Specific embodiments of the present application will be described hereinafter with reference to the accompanying drawings; however, it should be understood that the embodiments described are merely examples of the present application and that the present application may be implemented in a variety of ways. Familiar and / or repetitive functions and structures are not described in detail to avoid obscuring the present application with unnecessary or redundant details. Therefore, the specific structural and functional details disclosed herein are not intended to be limiting, but rather serve merely as a basis and representative basis for the claims to teach those skilled in the art to variously utilize the present application with substantially any suitable detailed structure.

[0029] This specification may use the phrases "in one embodiment," "in another embodiment," "in yet another embodiment," or "in other embodiments," which may all refer to one or more of the same or different embodiments according to the present application.

[0030] With the increasing development of electronic devices such as mobile phones that have camera modules 12, users' demand for shooting in multiple scenes is also increasing. In order to meet this demand, the existing electronic device camera modules 12 are becoming more and more complex and their sizes are also increasing. The increase in the size of the camera module 12 may cause the module to partially or completely protrude relative to the outer shell of the electronic device when it is integrated with the electronic device. This protruding structure will pose challenges to the structural strength and drop resistance: under the action of external forces such as falling, the protruding part will be deformed first, which may cause the chip on the motherboard near the protrusion to become unsoldered or the module body 13 to crack. If an air shock absorber is installed between the camera module 12 and the electronic device motherboard, since the volume of the air chamber 11 is fixed, when the external force causes the air to be rapidly compressed, the internal pressure will rise sharply. If this pressure increase is not effectively controlled and released, it may threaten the structural integrity of the air chamber 11, that is, it may cause the air chamber 11 to crack or trigger more serious safety accidents, and it will not be able to guarantee the shock absorption and safety of the camera module 12.

[0031] Reference Attachment Figure 1 -Attached Figure 4Embodiment 1 of the present invention proposes a shock-absorbing structure 15, comprising: a cylinder body 1, which has a receiving cavity inside; a movable part 2, one end of which is provided with a sealing portion 21, and the sealing portion 21 is slidably connected to the cavity wall of the receiving cavity to form a sealed air chamber 11 between the sealing portion 21 and the cylinder body 1; at least one overflow hole 3, which is provided in the cylinder body 1 and connected to the air chamber 11, and at least one overflow hole 3 is provided with an elastic diaphragm 4 for adjusting the pressure in the air chamber 11.

[0032] In one possible case, the shock absorbing structure 15 can be applied to electronic devices, including but not limited to mobile phones, laptop computers, tablet computers, etc. The shock absorbing structure 15 can also be applied to non-electronic devices, including but not limited to cups, kettles, etc. The shape of the cylinder body 1 can be any shape, such as cylindrical, square cylindrical and prismatic, etc. The cylinder body 1 has a receiving cavity inside, and the receiving cavity is used to receive the movable part 2. The size of the receiving cavity can be set according to actual needs and is not specifically limited here. A sealing portion 21 is provided at one end of the movable part 2. The outer periphery of the sealing portion 21 is tightly attached to the cavity wall of the receiving cavity, and the sealing portion 21 can be an elastic material, and its outer periphery is elastically abutted against the cavity wall of the receiving cavity, or the sealing portion 21 can be connected to the cavity wall by sliding with a groove or a slider to form a sealed air chamber 11 between the sealing portion 21 and the cylinder body 1. As the sealing portion 21 slides along the cavity wall, the volume and air pressure of the air chamber 11 can change. When the sealing part 21 slides toward the bottom of the air chamber 11, the air pressure in the air chamber 11 increases. When the sealing part 21 slides away from the bottom of the air chamber 11, the air pressure in the air chamber 11 gradually decreases. The cylinder body 1 is provided with an overflow hole 3. The number of overflow holes 3 can be any number and can be set according to actual needs, such as one overflow hole 3 or multiple overflow holes 3. The overflow hole 3 is connected to the air chamber 11 in this application, which means that the gas in the air chamber 11 can flow out of the cylinder body 1 through the overflow hole 3 or the gas outside the cylinder body 1 flows into the air chamber 11 through the overflow hole 3. The size of the multiple overflow holes 3 can be set according to actual needs, and the size of the multiple overflow holes 3 can be the same or different. In addition, the specific position of one or more overflow holes 3 in the cylinder body 1 is not limited here. In one embodiment, the diameter of the overflow hole 3 can be less than or equal to 1 mm to control the flow rate of the gas and avoid rapid pressure relief due to excessively large apertures, which affects the normal operation of the shock absorbing structure 15.

[0033] The shock-absorbing structure 15 also includes an elastic diaphragm 4. The elastic diaphragm 4 is disposed on at least one overflow hole 3, that is, all overflow holes 3 or some overflow holes 3 may be equipped with the elastic diaphragm 4. The elastic diaphragm 4 may be secured to the wall of the overflow hole 3 by welding or bonding, and its shape is adapted to that of the overflow hole 3. The elastic diaphragm 4 is elastically deformable, and its central portion may be designed as a thinner diaphragm. When the pressure in the air chamber 11 exceeds a certain value, the diaphragm is pushed open, allowing gas to be discharged through the overflow hole 3. When the pressure in the air chamber 11 decreases, the diaphragm automatically closes. Alternatively, the elastic diaphragm 4 may include a first diaphragm and a second diaphragm. The first and second diaphragms may be spliced ​​together, or they may be separate diaphragms with adjacent edges overlapping. When the diaphragms deform, the overlapping area changes, creating gaps of varying sizes for airflow. The opening and closing degrees of the first diaphragm and the second diaphragm can be changed according to the pressure changes in the air chamber 11. For example, when the pressure in the air chamber 11 increases, the opening and closing degrees of the first diaphragm and the second diaphragm increase; when the pressure in the air chamber 11 decreases, the opening and closing degrees of the first diaphragm and the second diaphragm decrease, so as to adjust the overflow amount of the overflow hole 3.

[0034] In addition, to further prevent the shock-absorbing structure 15 from being damaged by a sudden impact, such as the sealing portion 21 of the movable part 2 colliding with the bottom of the air chamber 11 and thereby damaging the sealing portion 21 or the cylinder body 1, a buffer pad 14 may be provided at the bottom of the air chamber 11. The buffer pad 14 is typically made of a material with good elasticity and wear resistance, such as rubber, silicone, or other polymer composite materials. When the sealing portion 21 of the movable part 2 collides with the bottom of the air chamber 11, it can absorb some of the energy, thereby reducing the impact force and protecting the internal components of the shock-absorbing structure 15 from damage.

[0035] The shock-absorbing structure 15 provided in this application includes a cylinder 1, a movable part 2, an overflow hole 3, and an elastic diaphragm 4. The cylinder 1 is provided with at least one overflow hole 3, and at least one overflow hole 3 is equipped with an elastic diaphragm 4. When the movable part 2 is subjected to a sudden impact, the external force causes the pressure in the air chamber 11 to rise sharply, the elastic diaphragm 4 to deform and increase, and the overflow outlet increases. When the pressure in the air chamber 11 decreases, the elastic diaphragm 4 returns to its original shape, and the overflow outlet decreases. The elastic diaphragm 4 can promptly and quickly release the air pressure in the air chamber 11, effectively preventing structural damage and explosion caused by excessive pressure in the air chamber 11, thereby improving the safety performance of the shock-absorbing structure. Furthermore, in an embodiment where the shock-absorbing structure 15 is applied to shock the camera module 12 of an electronic device, the safety of the camera module 12 can be improved.

[0036] In some modified embodiments of the first aspect of the present application, the shock-absorbing structure 15 also includes: a limiting portion 5, which is arranged at the end of the movable part 2 facing away from the sealing portion 21; an elastic part 6, one end of which abuts against the limiting portion 5 and the other end abuts against the cylinder body 1, and the elastic part 6 can be extended and retracted along the sliding direction of the sealing portion 21.

[0037] In one possible scenario, Figure 1 As shown, the shock absorbing structure 15 also includes a limiting portion 5, which is arranged at the end of the movable part 2 away from the sealing portion 21. It can be a whole with the movable part 2 or a component that is independent of the movable part 2 and fixed to the movable part 2 by welding or bolting. It protrudes from the outer peripheral surface of the movable part 2 and can be used to limit the telescopic stroke of the elastic part 6. The elastic part 6 is an element that can produce elastic deformation under the action of external force and restore its original shape after the external force is removed, such as a coil spring, a wave spring, etc. One end of the elastic part 6 abuts against the limiting portion 5, and the other end abuts against the cylinder body 1. When the sealing portion 21 slides in the accommodating cavity, the elastic part 6 can expand and contract along the sliding direction of the sealing portion 21. For example, when the limiting portion 5 is subjected to external impact, the sealing portion 21 slides toward the bottom of the air chamber 11, and the elastic part 6 is compressed to store elastic potential energy. When the sliding of the sealing part 21 is completed, since the elastic part 6 is in a compressed state, its elastic restoring force causes it to stretch, thereby giving the movable part 2 a force to restore its original state. This restoring force causes the sealing part 21 to slide in a direction away from the bottom of the air chamber 11 and return to its original position. In addition, when the sealing part 21 slides toward the bottom of the air chamber 11, the elastic part 6 is compressed, and the pressure in the air chamber 11 increases. When the sliding of the sealing part 21 is completed, the elastic restoring force of the elastic part 6 causes it to stretch, pushing the sealing part 21 to slide in a direction away from the bottom of the air chamber 11, releasing part of the pressure in the air chamber 11. The expansion and contraction of the elastic part 6 is continuous, and it can dynamically adjust the pressure in the air chamber 11 according to the size and duration of the external impact to ensure that the pressure is always within a safe range.

[0038] In some embodiments, the elastic diaphragm 4 can be elastically deformed according to the pressure applied to the air chamber 11 , and is provided with at least one air hole 41 . The opening of the at least one air hole 41 changes with the deformation of the elastic diaphragm 4 .

[0039] In one possible scenario, Figure 4As shown, the elastic diaphragm 4 is a component that can undergo elastic deformation under the action of pressure and return to its original shape after the external force is removed. It has at least one air hole 41, and the number of air holes 41 can be set according to actual needs. When the pressure in the air chamber 11 increases, the elastic diaphragm 4 deforms and increases, thereby increasing the aperture of the air hole 41 and accelerating the discharge speed of the gas in the air chamber 11; when the pressure in the air chamber 11 decreases, the elastic diaphragm 4 returns to its original shape, the aperture of the air hole 41 decreases, and the discharge speed slows down. The elastic diaphragm 4 can be made of natural rubber, silicone rubber, etc. The opening of the air hole 41 changes with the deformation of the elastic diaphragm 4, thereby adjusting the pressure in the air chamber 11, and the response speed is fast, ensuring that the pressure is always within a safe range.

[0040] In some embodiments, the sealing portion 21 is elastic and has an arc-shaped connecting surface 22 for connecting to the cavity wall.

[0041] In one possible case, in order to improve the sealing performance, the sealing portion 21 can be made of an elastic material, such as rubber, polyurethane, etc. These materials have good elasticity and sealing performance, can deform under pressure, and return to their original shape after the external force is removed. The elastic sealing portion 21 can form a close contact between the sealing portion 21 and the cavity wall, ensuring the sealing of the air chamber 11 and preventing gas leakage. Figure 1 As shown, the edge of the sealing portion 21 is designed as an arcuate connecting surface 22, which forms a smooth transition with the contact surface of the cavity wall, thereby increasing the contact area between the sealing portion 21 and the cavity wall and improving the sealing effect. At the same time, the arcuate connecting surface 22 can reduce friction, reduce the wear of the sealing portion 21 during the sliding process, and extend its service life.

[0042] In some embodiments, the shock-absorbing structure 15 also includes: a first mounting surface 7, where the side of the limiting portion 5 opposite to the elastic member 6 is the first mounting surface 7, and the expansion and contraction direction of the elastic member 6 forms a first angle α with the first mounting surface 7; a second mounting surface 8, where the side of the cylinder body 1 facing away from the movable member 2 is the second mounting surface 8, and the expansion and contraction direction of the elastic member 6 forms a second angle β with the second mounting surface 8; wherein the first angle α is not equal to the second angle β.

[0043] In one possible scenario, Figure 3As shown, the shock absorbing structure 15 can be applied to the camera module 12 of the electronic device, and can provide a buffering and shock absorbing effect for the camera module 12 when the electronic device is accidentally dropped. The electronic devices described here include but are not limited to mobile phones, laptop computers or tablet computers. The shock absorbing structure 15 can be arranged between the camera module 12 and the main bracket 13 of the electronic device. In order to prevent drops from multiple angles, the shock absorbing structure 15 is provided with a first mounting surface 7. The first mounting surface 7 is the side opposite to the limiting part 5 and the elastic part 6. The size of the first mounting surface 7 can be set according to actual needs, and the first mounting surface 7 can be any shape, such as: rectangle, square or polygon. The side of the cylinder body 1 facing away from the movable part 2 is the second mounting surface 8. The size of the second mounting surface 8 can be set according to actual needs, and the second mounting surface 8 can be any shape, such as: rectangle, square or polygon. The first mounting surface 7 is used to connect to the camera module 12, and the second mounting surface 8 is used to connect to the main bracket 13 of the electronic device; or the first mounting surface 7 is used to connect to the main bracket 13 of the electronic device, and the second mounting surface 8 is used to connect to the camera module 12. Both the first mounting surface 7 and the second mounting surface 8 can be connected to the camera module 12 or the main bracket 13 of the electronic device by bolt connection, gluing or snap connection. The first mounting surface 7 forms a first angle α with the extension and contraction direction of the elastic member 6, and the second mounting surface 8 forms a second angle β with the elastic member 6. The first angle α is not equal to the second angle β, such as: the first angle α is 60°, and the second angle β is 120°; the first angle α is 50°, and the second angle β is 130°, etc. The angles of the first angle α and the second angle β can be set according to actual needs. Multiple shock-absorbing structures 15 can be set between the same camera module 12 and the electronic device. The first mounting surface 7 of each shock-absorbing structure 15 has a different first angle α with the elastic member 6, so that multiple different shock-absorbing structures 15 can be used to achieve multi-angle buffering and shock absorption, thereby achieving better shock absorption effect.

[0044] In some embodiments, the shock-absorbing structure 15 also includes: a third mounting surface 9, which is arranged on the side opposite to the limiting portion 5 and the elastic member 6, and the elastic member 6 forms a third angle θ with the third mounting surface 9, and the third mounting surface 9 intersects with the first mounting surface 7; and / or, a fourth mounting surface 10, which is arranged on the side of the cylinder body 1 away from the movable member 2, and a fourth angle ε is formed between the extension and contraction direction of the elastic member 6 and the fourth mounting surface 10, and the fourth mounting surface 10 intersects with the second mounting surface 8.

[0045] In one possible scenario, Figure 3As shown, the shock absorbing structure 15 also includes a third mounting surface 9, that is, the end of the limiting portion 5 of the shock absorbing structure 15 opposite to the elastic member 6 can be provided with both the third mounting surface 9 and the first mounting surface 7, and the side of the cylinder body 1 facing away from the movable member 2 is provided with the second mounting surface 8 and the fourth mounting surface 10; or the end of the limiting portion 5 of the shock absorbing structure 15 opposite to the elastic member 6 is provided with the first mounting surface 7, and the side of the cylinder body 1 facing away from the movable member 2 is provided with the second mounting surface 8 and the fourth mounting surface 10; or the end of the limiting portion 5 of the shock absorbing structure 15 opposite to the elastic member 6 is provided with the first mounting surface 7 and the third mounting surface 9, and the side of the cylinder body 1 facing away from the movable member 2 is provided with the second mounting surface 8, etc. Among them, the first mounting surface 7 and the third mounting surface 9 can be connected to any two intersecting surfaces of the camera module 12 or the electronic device by bolts or welding, respectively, and the first angle α between the first mounting surface 7 and the elastic member 6 and the third angle θ between the third mounting surface 9 and the elastic member 6 can be equal or different. The fourth mounting surface 10 and the third mounting surface 9 can be connected to any two intersecting surfaces of the electronic device or camera module 12 by bolts or welding. The fourth angle ε between the fourth mounting surface 10 and the elastic member 6 and the second angle β between the second mounting surface 8 and the elastic member 6 can be equal or different. The shock-absorbing structure 15 is provided with multiple mounting surfaces. When any mounting surface is subjected to force, the multiple mounting surfaces can disperse the impact force in multiple directions, so that the force is more evenly distributed across the multiple mounting surfaces, thereby driving the elastic member 6 to compress along its contraction direction. This design not only improves the stability of the structure, but also optimizes the shock-absorbing effect, enabling it to achieve buffering in multiple directions.

[0046] The second aspect of the present application provides a camera module 12, including: a module body 122, which has a first surface 121; a shock-absorbing structure 15, which is arranged on the first surface 121 of the module body 122, and the shock-absorbing structure 15 includes: a cylinder body 1, which has a accommodating cavity inside; a movable part 2, one end of which is provided with a sealing part 21, and the sealing part 21 is slidably connected to the cavity wall of the accommodating cavity to form a sealed air chamber 11 between the sealing part 21 and the cylinder body 1; at least one overflow hole 3, which is provided in the cylinder body 1 and connected to the air chamber 11, and at least one overflow hole 3 is provided with an elastic diaphragm 4 for adjusting the pressure in the air chamber 11.

[0047] In one possible case, as Figure 2 , Attachment Figure 5 As shown, the present application provides a camera module 12, which is a component in an electronic device for capturing images and videos, including but not limited to a lens, an image sensor, an image signal processor, a focus motor and a flash. Figure 4 As shown in FIG, the raised structure provided on the side of the module body 122 opposite to the first surface 121 can be a lens, a flash, etc. The objects used by the camera module 12 include but are not limited to mobile phones, tablet computers, medical equipment and laptop computers. Figure 2As shown, the first surface 121 of the camera module 12 is used to connect and fix the shock-absorbing structure 15. The first surface 121 can be a smooth surface or include two intersecting surfaces. The number of shock-absorbing structures 15 on the camera module 12 can be one or more, and the position of the shock-absorbing structure 15 on the first surface 121 can be arranged as needed.

[0048] The camera module 12 provided in this application, when subjected to an impact, causes the pressure in the air chamber 11 to rise sharply, further deforming the elastic diaphragm 4 and increasing the overflow outlet. When the pressure in the air chamber 11 decreases, the elastic diaphragm 4 returns to its original shape, and the overflow outlet decreases. The elastic diaphragm 4 can promptly and quickly release the air pressure in the air chamber 11, effectively preventing structural damage and explosion caused by excessive pressure in the air chamber 11, thereby improving the safety performance of the shock absorber.

[0049] In one possible scenario, Figure 2 As shown, when the raised structure provided on the side of the module body 122 opposite to the first surface 121 is a component such as a lens or a flash, when the camera module 12 is impacted by an external force, at least part of the external force acts on the lens or flash component, and at least part of the direction of the external force is perpendicular to the lens or flash component, that is, it acts on the camera module along the fifth direction F or acts on the camera module along the first direction A. The elastic member 6 in the shock-absorbing structure 15 is rapidly compressed and deformed along the fifth direction F or the first direction A, and the gas in the air chamber 11 is compressed. Since the compression and expansion of the gas takes time, the impact force is gradually absorbed and weakened, thereby achieving a shock-absorbing effect.

[0050] The third aspect of the present application provides an electronic device, including: a main bracket 13; a part to be shock-absorbed; a shock-absorbing structure 15, arranged between the main bracket 13 and the part to be shock-absorbed, the shock-absorbing structure 15 including: a cylinder body 1, which has a accommodating cavity inside; a movable part 2, one end of which is provided with a sealing part 21, the sealing part 21 is slidably connected to the cavity wall of the accommodating cavity to form a sealed air chamber 11 between the sealing part 21 and the cylinder body 1; at least one overflow hole 3, arranged in the cylinder body 1 and connected to the air chamber 11, at least one overflow hole 3 is provided with an elastic diaphragm 4 for adjusting the pressure in the air chamber 11.

[0051] In one possible case, as Figure 5 , Attachment Figure 6As shown, the electronic devices mentioned in this application include but are not limited to mobile phones, tablet computers, or laptop computers. The main frame 13 is used to support the shock-absorbing structure 15 and the components to be shock-absorbing of the electronic device. The main frame 13 can be a component such as the housing or motherboard of the electronic device. The components to be shock-absorbing include but are not limited to the camera module 12, display screen, keyboard assembly, etc. In addition, the application locations of the shock-absorbing structure 15 include but are not limited to: application between the rear camera of the mobile phone and the main frame 13, and can also be applied between the front camera of the mobile phone and the main frame 13. Here, the electronic device is a mobile phone, the main frame 13 is the motherboard, and the component to be shock-absorbing is the camera module 12. To prevent the camera module 12 of the mobile phone from being damaged by the impact force of the ground when the mobile phone falls, the shock-absorbing structure 15 is arranged between the camera module 12 and the motherboard. The number of shock-absorbing structures 15 can be one or more, and the location of the shock-absorbing structures 15 can be set as needed, such as: placing a shock-absorbing structure 15 on each side of the camera module 12, or placing one or more camera modules 12 in the center of the camera module 12, etc.

[0052] The installation direction of the shock absorbing structure 15 can be as follows: Figure 3 , Attachment Figure 5 As shown, the first mounting surface 7 of the shock-absorbing structure 15 can be connected to the camera module 12 by welding, bolting, or the like, and the second mounting surface 8 of the shock-absorbing structure 15 can be connected to the mainboard by welding, bolting, or the like, or the first mounting surface 7 of the shock-absorbing structure 15 can be connected to the mainboard by welding, bolting, or the like, and the second mounting surface 8 of the shock-absorbing structure 15 can be connected to the camera module 12 by welding, bolting, or the like. The first angle α formed between the first mounting surface 7 and the elastic member 6 can be equal to or different from the second angle β formed between the second mounting surface 8 and the elastic member 6. The magnitudes of the first angle α and the second angle β can be set according to different buffering and shock-absorbing requirements. For example, when the camera module 12 and the mainboard used to connect the shock-absorbing structure 15 are relatively parallel, the first angle α and the second angle β can both be set to 90°. The compression direction of the elastic member 6 is the first direction A. When the camera module 12 is subjected to an impact force along the first direction A, the elastic member 6 can quickly deform, thereby absorbing the impact energy and reducing the vibration and impact force transmitted to the camera module 12. This helps protect key components such as the lens and image sensor within the camera module 12 and prolongs their service life. When the camera module 12 and the mainboard, which are connected to the shock-absorbing structure 15, are relatively parallel, the first angle α and the second angle β can be set to two unequal angles, and the elastic member 6 is compressed in the second direction B. When the camera module 12 is subjected to an impact force in the second direction B, the elastic member 6 can quickly deform, thereby absorbing the impact energy and reducing the vibration and impact force transmitted to the interior of the camera module 12.

[0053] In the electronic device provided in this application, when the shock-absorbing component is subjected to an impact, the external force causes the pressure in the air chamber 11 to rise sharply, causing the elastic diaphragm 4 to deform more and increase the overflow outlet. When the pressure in the air chamber 11 decreases, the elastic diaphragm 4 returns to its original shape, and the overflow outlet decreases. The elastic diaphragm 4 can promptly and quickly release the air pressure in the air chamber 11, effectively preventing structural damage and explosion caused by excessive pressure in the air chamber 11, thereby improving the safety performance of the shock absorber.

[0054] In some modified implementations of the third aspect of the present application, the number of shock-absorbing structures 15 is multiple, including: at least one first shock-absorbing structure 15, which has a first mounting surface 7 and a second mounting surface 8, and its first angle α is equal to the second angle β; and / or, at least one second shock-absorbing structure 15, which has a first mounting surface 7 and a second mounting surface 8, and its first angle α is not equal to the second angle β; and / or, at least one third shock-absorbing structure 15, which has a first mounting surface 7, a second mounting surface 8, a third mounting surface 9 and a fourth mounting surface 10, and the third mounting surface 9 intersects with the first mounting surface 7, and the fourth mounting surface 10 intersects with the second mounting surface 8.

[0055] In one possible case, the electronic device is a mobile phone, the main frame 13 is a motherboard, and the part to be damped is a camera module 12. In the electronic device, multiple or multiple damping structures 15 can be installed between the main frame 13 and the part to be damped to achieve different damping effects.

[0056] As attached Figure 3 As shown, one or more first shock-absorbing structures having a first mounting surface 7 and a second mounting surface 8 are installed between the component to be shock-absorbing and the bracket body, and the first angle α between the first mounting surface 7 and the elastic component 6 is equal to the second angle β between the second mounting surface 8 and the elastic component 6. In this case, when the component to be shock-absorbing of the electronic device is subjected to an impact force along the first direction A, the elastic component 6 can be rapidly deformed and compressed along the first direction A to absorb the impact energy, thereby reducing the vibration and impact force transmitted to the interior of the camera module 12. In order to achieve shock absorption and buffering at multiple positions, multiple first shock-absorbing structures 15 as described above can be installed at different positions of the camera module 12.

[0057] One or more second shock-absorbing structures having a first mounting surface 7 and a second mounting surface 8 are installed between the part to be shock-absorbing and the bracket body, and the first angle α between the first mounting surface 7 and the elastic part 6 is not equal to the second angle β between the second mounting surface 8 and the elastic part 6. In this case, when the part to be shock-absorbing of the electronic device is subjected to an impact force along the second direction B, the elastic part 6 can be quickly deformed and compressed along the second direction B to absorb the impact energy, reducing the vibration and impact force transmitted to the inside of the camera module 12. In order to achieve shock absorption and buffering in multiple directions, multiple second shock-absorbing structures as described above can be installed at different positions of the camera module 12, and the first angle α of each second shock-absorbing structure can be different, and the second angle β of multiple second shock-absorbing structures 15 can be different.

[0058] One or more third shock-absorbing structures having a first mounting surface 7, a second mounting surface 8, a third mounting surface 9, and a fourth mounting surface 10 are installed between the component to be shock-absorbed and the bracket body, with the third mounting surface 9 intersecting with the first mounting surface 7, and the fourth mounting surface 10 intersecting with the second mounting surface 8. The first mounting surface 7 and the third mounting surface 9 contact the component to be shock-absorbed, while the second mounting surface 8 and the fourth mounting surface 10 contact the bracket body. When the component to be shock-absorbed is subjected to an impact force along the third direction C or the fourth direction D, the third mounting surface 9 and the first mounting surface 7 can disperse the impact force and transmit it to the elastic member 6, thereby absorbing the impact energy. Similarly, the second mounting surface 8 and the fourth mounting surface 10 can also share the impact force transmitted to the bracket body. By installing a multi-faceted third shock-absorbing structure 15 between the component to be shock-absorbed and the bracket body, impact forces can be effectively dispersed and absorbed in multiple directions, thereby improving the impact resistance and stability of the camera module 12 or other electronic equipment.

[0059] The above-mentioned first shock-absorbing structure, second shock-absorbing structure, and third shock-absorbing structure can be freely combined in any number to achieve shock-absorbing effects at different angles and positions. For example, one or more first shock-absorbing structures are set at the center of the camera module 12 to absorb the impact force in the first direction A, and multiple second shock-absorbing structures are set around the camera module 12 to absorb the impact force in the second direction B; or a third shock-absorbing structure is set at the center of the camera module 12 to absorb the impact force in the third direction C or the fourth direction D, and multiple second shock-absorbing structures are set on the periphery of the camera module 12 to absorb the impact force in the second direction B, etc.

[0060] In some embodiments, the air chambers 11 of the multiple shock absorbing structures 15 are interconnected.

[0061] In one possible scenario, the air chambers 11 of multiple shock-absorbing structures 15 are interconnected, such as: the air chambers 11 of the first shock-absorbing structure and the second shock-absorbing structure are interconnected, or the air chambers 11 of the second shock-absorbing structure and the third shock-absorbing structure are interconnected, or the air chambers 11 of the first shock-absorbing structure and the third shock-absorbing structure are interconnected, or the air chambers 11 of the first shock-absorbing structure and the third shock-absorbing structure are interconnected, or the air chambers 11 of the first shock-absorbing structure, the second shock-absorbing structure, and the third shock-absorbing structure are interconnected. When a shock-absorbing structure 15 is impacted, the pressure in its air chamber 11 can be quickly transferred and dispersed to the other air chambers 11 through the interconnected air chambers 11. This prevents a single air chamber 11 from being subjected to excessive pressure, thereby reducing the risk of local overload, explosion, or damage to the air chamber 11, and further improving the shock absorption effect.
