Description

Technical Field

[0001] This application belongs to the field of electronic equipment technology, and specifically relates to an electronic device. Background Technology

[0002] In order to improve the user's grip on electronic devices and to achieve the trend of making electronic devices thinner and lighter, some electronic devices have low rigidity and soft texture of the cover. In some usage scenarios, the decorative parts of the camera will undergo large downward deformation. There is a phenomenon that the decorative parts can damage the battery cell by deforming the cover, which in turn causes a strong impact on the battery cell and poses a high risk to battery safety. Summary of the Invention

[0003] This application aims to provide an electronic device that solves the problem of piezoelectric cells appearing due to deformation of the cover caused by decorative parts, which in turn leads to safety risks to the battery.

[0004] To solve the above-mentioned technical problems, this application is implemented as follows:

[0005] This application provides an electronic device, including:

[0006] Battery cell;

[0007] The cover is located on one side of the battery cell, and the side of the cover facing the battery cell has a first clearance groove;

[0008] Decorative parts are attached to the side of the cover that faces away from the battery cell;

[0009] The buffer element is located between the first clearance groove and the battery cell along the thickness direction of the cover, and part of the buffer element is located between the decorative element and the battery cell.

[0010] In the embodiments of this application, a first clearance groove is provided on the side of the cover facing the battery cell. The first clearance groove is a groove structure formed by recessing from the inner surface of the cover. The function of the first clearance groove is to increase the spatial distance between the cover and the battery cell, thereby providing clearance for the battery cell in the thickness direction of the whole machine, so that the external impact force is attenuated by a larger air gap before being transmitted to the battery cell.

[0011] The decorative element is a circular structural component surrounding the camera module, connected to the side of the cover away from the battery cell. The orthographic projection of the decorative element on the cover overlaps with the orthographic projection of the battery cell on the cover. This overlapping area is a dangerous area where the decorative element may directly compress the battery cell during a drop. At least a portion of the first clearance groove is located within this overlapping area, allowing the first clearance groove to be aligned with the risky position where the decorative element might press against the battery cell, thus providing a larger buffer space for the battery cell head when the decorative element is impacted and pressed down.

[0012] The buffer is a flexible material component with a certain elasticity and compressibility. The buffer is filled in the first relief groove. The function of the buffer is to provide reverse support force when the cover is pressed normally to eliminate the pressing play caused by the first relief groove. At the same time, when the decorative part is subjected to a drop impact and presses down on the cover, the buffer can be compressed and absorb part of the impact energy. During the compression deformation process, the buffer converts kinetic energy into elastic potential energy, thereby reducing the impact force transmitted to the battery cell. The buffer and the first relief groove of the cover work together to achieve the dual protection effect of increasing the safety gap and absorbing impact energy, which fully ensures the safety of the battery cell in the scenario where the decorative part presses down on the battery cell.

[0033] The following is combined with Figures 1-12 This application describes an electronic device according to an embodiment of the present application.

[0034] Combination Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 11 As shown, in some embodiments of this application, an electronic device 100 is proposed, comprising: a battery cell 110, a cover 120, a decorative element 130, and a buffer element 140. The cover 120 is located on one side of the battery cell 110, and a first clearance groove 121 is provided on the side of the cover 120 facing the battery cell 110. The decorative element 130 is connected to the side of the cover 120 away from the battery cell 110, along the thickness direction of the cover 120 (…). Figure 1 (The arrow at point A points to) The buffer 140 is located between the first clearance groove 121 and the battery cell 110, and part of the buffer 140 is located between the decorative part 130 and the battery cell 110.

[0035] The battery cell 110 is a component in the electronic device 100 that stores electrical energy. The battery cell 110 is prone to deformation or even safety accidents when subjected to external mechanical impact or compression. The cover 120 is a shell component located on one side of the battery cell 110. The cover 120 covers one side of the battery cell 110 and serves to protect the internal components, form the appearance of the device, and provide a mounting base for components such as cameras.

[0036] The cover 120 is provided with a first clearance groove 121 on the side facing the battery cell 110. The first clearance groove 121 is a groove structure formed by recessing from the inner surface of the cover 120. The function of the first clearance groove 121 is to increase the spatial distance between the cover 120 and the battery cell 110, thereby providing clearance for the battery cell 110 in the thickness direction of the whole machine, so that the external impact force is attenuated by a larger air gap before being transmitted to the battery cell 110.

[0037] The decorative element 130 may be a circular structural component surrounding the camera module, and is connected to the side of the cover 120 opposite to the battery cell 110. The orthographic projection of the decorative element 130 on the cover 120 overlaps with the orthographic projection of the battery cell 110 on the cover 120. This overlapping area is a dangerous area where the decorative element 130 may directly compress the battery cell 110 during a drop. Figure 2 The area within the dashed box), at least a portion of the first clearance groove 121 is located within this overlapping area, so that the first clearance groove 121 is aligned with the risk position of the decorative piece 130 and the cell 110 is specifically cleared, so that the head of the cell 110 has a large buffer space when the decorative piece 130 is impacted and pressed down.

[0038] The buffer 140 is a flexible material component with a certain elasticity and compressibility. The buffer 140 is filled in the first relief groove 121 and is located between the first relief groove 121 and the battery cell 110. Part of the buffer 140 is located between the decorative component 130 and the battery cell 110. The function of the buffer 140 is to provide reverse support force when the cover 120 is pressed normally to eliminate the pressing misalignment caused by the first relief groove 121. At the same time, when the decorative component 130 is subjected to a drop impact and presses down on the cover 120, the buffer 140 can be compressed and absorb part of the impact energy. During the compression deformation process, the buffer 140 converts kinetic energy into elastic potential energy, thereby reducing the impact force transmitted to the battery cell 110. The buffer 140 and the first relief groove 121 of the cover 120 cooperate to achieve the dual protection effect of increasing the safety gap and absorbing impact energy, which fully ensures the safety of the battery cell 110 in the scenario where the decorative component 130 presses down on the battery cell 110.

[0039] For example, the cover 120 in this embodiment is a cover made of fiberglass.

[0040] In one possible embodiment, along the thickness direction of the cover 120, the projection of the decorative element 130 onto the plane where the cell 110 is located overlaps with the projection of the buffer element 140 onto the plane where the cell 110 is located.

[0041] The projection of the decorative element 130 onto the plane where the battery cell 110 is located overlaps with the projection of the buffer element 140 onto the plane where the battery cell 110 is located. This overlapping area is a dangerous area where the decorative element 130 may directly press against the battery cell 110 during a fall. The first clearance groove 121 is aligned with the risk position where the decorative element 130 presses against the battery cell 110 to provide targeted clearance.

[0042] Combination Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, in one possible embodiment, the electronic device 100 further includes a frame 101, and a cover 120 having a mating plane 122 in the area outside the first clearance groove 121 on the side facing the battery cell 110, and the frame 101 supporting the mating plane 122.

[0043] The frame 101 is a frame structure in the electronic device 100 used to support and fix internal components. The cover 120 has a mating plane 122 on the side facing the battery cell 110 outside the first relief groove 121. The mating plane 122 is a flat area on the inner surface of the cover 120 that is not degummed. The function of the mating plane 122 is to provide a support surface that directly contacts the frame 101, so that the cover 120 can form a stable mating relationship with the frame 101 in the area where the adhesive is not removed.

[0044] The frame 101 supports the mating plane 122, thereby providing rigid support for most areas of the cover 120 and preventing the cover 120 from undergoing unexpected bending deformation due to stress during normal use. The presence of the mating plane 122 ensures that the first clearance groove 121 is only located in a partial projection area of ​​the piezoelectric core 110 of the decorative part 130, while other areas of the cover 120 still maintain a large-area fit and support with the frame 101. This design achieves targeted clearance protection in dangerous areas and maintains sufficient overall rigidity and structural stability in non-dangerous areas, avoiding the problem of reduced overall strength and collapse of the cover 120 due to large-area glue removal.

[0045] Combination Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, in one possible embodiment, the sidewall of the first clearance groove 121 is a transitional inclined surface 123.

[0046] The transition inclined surface 123 is an inclined structure connecting the bottom wall of the first clearance groove 121 and the mating plane 122. The function of the transition inclined surface 123 is to smoothly transition between the bottom wall of the first clearance groove 121 and the mating plane 122.

[0047] If the bottom wall of the first clearance groove 121 and the mating plane 122 adopt a right-angle transition, a visible thickness difference mark defect will appear on the corresponding position of the outer surface 127 of the cover 120 due to the sudden change in wall thickness, affecting the appearance quality of the electronic device 100. The transition inclined surface 123 eliminates the appearance defects caused by the abrupt change in wall thickness. The transition inclined surface 123 can also improve the stress distribution of the cover 120 in the transition area. When the device is dropped or the cover 120 is impacted, the transition inclined surface 123 can effectively disperse the stress concentration and prevent the cover 120 from cracking or breaking at the edge of the adhesive removal.

[0048] In this embodiment, the transition inclined surface 123 is a rounded transition inclined surface. In other embodiments, the transition inclined surface 123 can also be a chamfered inclined surface.

[0049] In one possible embodiment, the electronic device 100 further includes a frame 103 and a middle plate 102, the frame 103 being disposed around the middle plate 102, the middle plate 102 being located on the side of the battery cell 110 facing away from the cover 120. In this embodiment, the frame 103 and the middle plate 102 constitute a frame 101.

[0050] The electronic device 100 also includes a bracket 160 located on the side of the middle plate 102 facing the decorative element 130.

[0051] The cover 120 is also provided with an assembly hole 124, and some decorative parts 130 are provided relative to the assembly hole 124. The first clearance groove 121 is located around the assembly hole 124.

[0052] like Figure 5 As shown, in one possible embodiment, the width of the transition inclined surface 123 is W, the depth of the transition inclined surface 123 is H, and W / H≥10.

[0053] The ratio of W to H is greater than or equal to 10, which defines the ratio of the width to the depth of the transition slope 123. When this range is met, the transition slope 123 exhibits a very gentle unfolding shape, meaning that the transition distance from the mating plane 122 to the bottom of the first clearance groove 121 on the inner surface of the cover 120 is long, and the wall thickness change is not obvious. This transition slope 123 with a large width-to-depth ratio can eliminate the problem of thickness difference marks on the outer surface 127 of the cover 120, because the slow wall thickness gradient will not form obvious light and dark boundaries or outline shadows on the outer surface 127.

[0054] Combination Figure 4 and Figure 5 As shown, in one possible embodiment, the buffer 140 covers at least a portion of the transition slope 123.

[0055] The cushioning element 140 completely covers the bottom wall of the first relief groove 121, minimizing the feeling of emptiness and collapse caused by the lack of support in the adhesive area when the user presses the cover 120. The cushioning element 140 also extends upwards to cover at least a portion of the transition slope surface 123, ensuring a close fit between the cushioning element 140 and the curved surface of the transition slope surface 123. This coverage of the cushioning element 140 in the transition slope surface 123 area increases the pressure contact area of ​​the cushioning element 140. When the decorative element 130 is subjected to a drop impact and presses down on the cover 120, the cushioning element 140 is compressed and deformed, absorbing the impact energy. Because the transition slope surface 123 itself has a certain unfolding width, the cushioning element 140 can more fully utilize the energy absorption characteristics of the elastic material. The buffer 140 covers both the bottom wall of the first relief groove 121 and the transition inclined surface 123, which maximizes the contact area between the buffer 140 and the cover 120, improving the structural stability and durability of the buffer 140 after repeated pressure, and preventing the buffer 140 from shifting or falling off during use.

[0056] The transition inclined surface 123 has a large width, which provides sufficient surface area for the buffer 140 to cover. The attachment area of ​​the buffer 140 on the transition inclined surface 123 is increased. When the buffer 140 is pressed down by the decorative part 130, the pressure can be distributed more evenly, avoiding the failure of the buffer 140 or the partial collapse of the cover 120 due to excessive local pressure.

[0057] Combination Figure 1 and Figure 2 As shown, in one possible embodiment, the cover 120 is provided with a mounting hole 124, a portion of the decorative element 130 extends into the mounting hole 124, a portion of the decorative element 130 is disposed opposite to the mounting hole 124, and a first clearance groove 121 is located circumferentially to the mounting hole 124. Figure 8 The arrow at C1 points to...

[0058] The edge of the buffer 140 is aligned with the inner wall of the mounting hole 124, or the edge of the buffer 140 is spaced apart from the inner wall of the mounting hole 124.

[0059] The cover 120 is provided with an assembly hole 124, which is an opening that penetrates through the thickness direction of the cover 120. The function of the assembly hole 124 is to provide a light path for the camera module and to provide an installation position for the decorative part 130.

[0060] The decorative element 130 can be nested with the cover 120 through the mounting hole 124. The edge of the buffer element 140 is aligned with the inner wall of the mounting hole 124, or the edge of the buffer element 140 is spaced apart from the inner wall of the mounting hole 124. Both cases define the horizontal boundary position of the buffer element 140. The edge of the buffer element 140 does not extend beyond the inner wall of the mounting hole 124. This design ensures that the buffer element 140 does not extend into the adhesive area connecting the decorative element 130 and the cover 120, avoiding interference between the adhesive between the decorative element 130 and the cover 120 and the buffer element 140, which would affect the bonding strength.

[0061] When the edge of the buffer 140 is spaced apart from the inner wall of the mounting hole 124, a certain gap is maintained between them. This gap provides sufficient operating space for the dispensing process between the decorative part 130 and the cover 120, and also reserves deformation allowance for the buffer 140 when it expands under pressure, preventing the buffer 140 from damaging the adhesive layer after expansion.

[0062] Combination Figure 1 , Figure 2 , Figure 9 and Figure 10 As shown, in one possible embodiment, the cover 120 further includes a protrusion 104 connected to the inner wall of the mounting hole 124. The protrusion 104 has one of a positioning hole 125 and a positioning post 131. The decorative piece has the other of the positioning hole 125 and the positioning post 131, with the positioning post 131 inserted into the positioning hole 125. The positioning hole 125 and the positioning post 131 are interlocked, and this interlocking fit allows the decorative piece 130 to be quickly aligned to the correct position during installation onto the cover 120, preventing the decorative piece 130 from rotating or shifting relative to the cover 120.

[0063] The positioning hole 125 and the positioning post 131 engage to prevent the decorative part 130 from shifting relative to the cover 120, thus maintaining a stable relative position between the decorative part 130 and the cover 120. This stable relative position ensures a predictable force transmission path when the decorative part 130 is pressed down, preventing impact force from directly acting on the non-protected area of ​​the battery cell 110 due to the decorative part 130 shifting. The engagement of the positioning hole 125 and the positioning post 131 also improves the overall assembly efficiency and yield, and reduces production costs.

[0064] Combination Figure 1 and Figure 2 As shown, in one possible embodiment, the electronic device 100 further includes a first support portion 151, which is located on the side of the middle plate 102 facing the decorative element 130. One end of the first support portion 151 is connected to the middle plate 102, and the other end of the first support portion 151 abuts against the decorative element 130.

[0065] The first support portion 151 is a rib structure that protrudes upward from the middle plate 102, forming a direct rigid support between the middle plate 102 and the decorative component 130. During the drop of the electronic device 100, the decorative component 130 will bend downward after being impacted. The first support portion 151, with its rigidity, resists the downward pressure of the decorative component 130, directly transmitting the impact force to the middle plate 102, which then distributes it throughout the entire structure. The rigid support of the first support portion 151 significantly shortens the free deformation stroke of the decorative component 130 in the impact direction, preventing the decorative component 130 from pressing down into the danger zone of the battery cell 110, thereby reducing the impact energy transmitted from the decorative component 130 to the battery cell 110.

[0066] The first clearance groove 121 increases the safety gap, the buffer 140 absorbs part of the impact energy, and the first support 151 restricts the downward displacement of the decorative part 130 from the source. The above three measures act on different stages of impact transmission and together constitute a multi-level protection system for the battery cell 110.

[0067] Combination Figure 1 , Figure 2 and Figure 6 As shown, in one possible embodiment, the electronic device 100 further includes a bracket 160 and a connector 170, the bracket 160 being located on the side of the middle plate 102 facing the decorative element 130. The connector 170 is located between the bracket 160 and the decorative element 130, and the bracket 160 is connected to the decorative element 130 via the connector 170.

[0068] The bracket 160 is a carrier component that supports and fixes the circuit board and related devices. The connector 170 is located between the bracket 160 and the decorative element 130. Exemplarily, the connector 170 is an adhesive material filling the gap between the bracket 160 and the decorative element 130. The bracket 160 supports the decorative element 130 through the connector 170, and the connector 170 forms a flexible adhesive support relationship between the bracket 160 and the decorative element 130. When the decorative element 130 is subjected to a drop impact, the downward pressure of the decorative element 130 is transmitted to the connector 170. The connector 170 undergoes a slight deformation due to its own viscoelastic properties and absorbs part of the impact energy. At the same time, the connector 170 evenly distributes the remaining impact force to the entire contact surface of the bracket 160, avoiding local stress concentration that could damage the bracket 160 or the decorative element 130.

[0069] The connector 170 also serves as a fixed connection, firmly bonding the decorative part 130 to the bracket 160 as a whole, improving the overall structural integrity of the machine during a drop and preventing the decorative part 130 from loosening or shifting. The support of the bracket 160 for the decorative part 130 through the connector 170 complements the direct rigid support of the first support part 151, suppressing the downward deformation of the decorative part 130 from different directions and through different mechanical mechanisms.

[0070] Combination Figure 1 , Figure 2 and Figure 7 As shown, in one possible embodiment, the bracket 160 is provided with a second support portion 152 on the side facing the decorative member 130, and the bracket 160 abuts against the decorative member 130 through the second support portion 152.

[0071] The bracket 160 supports the decorative piece 130 via the second support portion 152. The second support portion 152 establishes a force transmission path between the bracket 160 and the decorative piece 130. When the decorative piece 130 is subjected to a downward impact, the second support portion 152 transmits the force to the bracket 160, preventing the decorative piece 130 from sinking further.

[0072] This application uses multiple support structures to form a multi-dimensional support network for the decorative part 130, and applies support force from multiple positions of the decorative part 130 at the same time, so that the overall deformation of the decorative part 130 during the drop process is minimized, and the battery cell 110 is protected from the threat of downward impact from the decorative part 130 to the greatest extent.

[0073] In this embodiment, the second support portion 152 is a rib structure protruding on the bracket 160 towards the decorative member 130, and the decorative member 130 is provided with a third support portion 153 on the side facing the second support portion 152, and the third support portion 153 and the second support portion 152 abut against each other.

[0074] Combination Figure 1 , Figure 2 and Figure 8 As shown, in one possible embodiment, the electronic device 100 further includes a reinforcing member 182, which is located on the side of the bracket 160 facing the decorative member 130, and the reinforcing member 182 and the decorative member 130 are spaced apart.

[0075] The reinforcing member 182 is a rigid reinforcement structure attached to the surface of the circuit board. Its function is to improve the mechanical strength of a localized area of ​​the circuit board, preventing bending or breakage under stress. The reinforcing member 182 and the decorative member 130 are spaced apart, meaning a small gap exists between them. Under normal operating conditions, the reinforcing member 182 does not contact the decorative member 130, thus not interfering with its normal assembly and use. When the electronic device 100 is dropped and the decorative member 130 deforms under pressure, the decorative member 130 moves downwards until it contacts the reinforcing member 182. The reinforcing member 182, with its rigidity, prevents further downward movement of the decorative member 130 and transmits the impact force to the circuit board and the supporting structure below. The small gap between the reinforcing member 182 and the decorative member 130 means that the reinforcing member 182 does not participate in the support under normal conditions and will not increase the daily stress burden on the decorative member 130. Only under extreme drop conditions does the reinforcing member 182 play its role as the last line of defense.

[0076] For example, the gap between the reinforcement 182 and the decorative element 130 is less than or equal to 2 mm.

[0077] Combination Figure 1 , Figure 2 and Figure 8 As shown, in one possible embodiment, the electronic device further includes a reinforcing member 182 and a sealing ring 192. The reinforcing member 182 has an acoustic transducer 191 on its side opposite to the decorative member 130. The reinforcing member 182 has an opening 183 opposite to the acoustic transducer 191, and the opening 183 communicates with the sound inlet of the acoustic transducer 191. The sealing ring 192 is distributed circumferentially along the opening 183 and is located between the decorative member 130 and the reinforcing member 182. The reinforcing member 182 has an opening 183 directly opposite the acoustic transducer 191. The opening 183 is a hole penetrating the thickness direction of the reinforcing member 182 and communicates with the acoustic transducer 191. The function of the opening 183 is to provide a sound propagation channel for the acoustic transducer 191, allowing external sound to pass through the reinforcing member 182 and the circuit board to reach the acoustic transducer 191.

[0078] The sealing ring 192 is an annular sealing structure arranged around the opening 183, forming a closed seal between the decorative element 130 and the reinforcing element 182. The sealing ring 192 fills the assembly gap between the decorative element 130 and the reinforcing element 182, preventing external sound leakage from the assembly gap and thus avoiding a decrease in the sound reception quality of the acoustic transducer 191. The sealing ring 192 prevents dust, moisture, and other foreign matter from entering the acoustic transducer 191 through the opening 183, protecting the acoustic transducer 191 from contamination and corrosion. It is understood that the decorative element 130 may have a channel communicating with the acoustic transducer 191, through which the acoustic transducer 191 connects to the external environment.

[0079] When the decorative part 130 is subjected to a slight impact, the sealing ring 192 can absorb some of the vibration energy, reducing the direct transmission of the impact to the circuit board and the acoustic transducer 191.

[0080] Combination Figure 1 and Figure 3 As shown, in one possible embodiment, the cover 120 is further provided with a plurality of second clearance grooves 126 on the side facing the battery cell 110, and the plurality of second clearance grooves 126 are arranged along the circumference of the mounting hole 124. Figure 1 The arrow at C2 points to the distribution.

[0081] The second clearance groove 126 is an additional recessed structure on the inner surface of the cover 120, in addition to the first clearance groove 121. Multiple second clearance grooves 126 are distributed circumferentially along the decorative element 130, with at least a portion of each groove facing the projection area of ​​the decorative element 130 onto the cover 120. In the compact stacking of the electronic devices 100, the space beneath the decorative element 130 may contain other electrical components besides the battery cell 110, such as camera circuit boards, connectors, and sensors. These components also face the risk of being compressed by the decorative element 130 upon drop. The second clearance groove 126 provides partial clearance at the locations of these components, preventing the decorative element 130 from directly impacting the components below during its downward stroke, thus avoiding damage or malfunction due to mechanical impact.

[0082] The multiple second clearance slots 126 distributed circumferentially along the decorative element 130 mean that multiple potential pressure points beneath the decorative element 130 are specifically protected, extending the protection range from the battery cell 110 to other sensitive devices surrounding the decorative element 130. The arrangement of the second clearance slots 126 provides a safety guarantee for the high-density stacking of electronic devices 100 within a limited internal space. Combined with... Figure 1 and Figure 2 As shown, in one possible embodiment, the surface of the cover 120 facing away from the battery cell 110 is the appearance surface 127. The distance between the first side of the appearance surface 127 and the decorative element 130 is greater than the distance between the second side of the appearance surface 127 and the decorative element 130. In the direction from the first side of the appearance surface 127 to the second side of the appearance surface 127, the appearance surface 127 includes a first surface 128, a connecting surface 1271 and a second surface 129 connected in sequence. The decorative element 130 is connected to the second surface 129.

[0083] The surface of the cover 120 facing away from the battery cell 110 is the exterior surface 127. The exterior surface 127 is the visible surface when the user is using the electronic device 100 normally, and it determines the visual texture and grip feel of the device. The distance between the first side of the exterior surface 127 and the decorative element 130 is greater than the distance between the second side of the exterior surface 127 and the decorative element 130. The first side of the exterior surface 127 is the bottom side of the electronic device 100, and the second side of the exterior surface 127 is the top side of the electronic device 100.

[0084] The surface 127 includes a first surface 128, a connecting surface 1271, and a second surface 129 connected in sequence. The first surface 128 transitions to the second surface 129 through the connecting surface 1271. It can be understood that the connecting surface 1271 is an inclined surface, and the first surface 128 and the second surface 129 are located on different planes.

[0085] When the first clearance groove 121 is opened on the side of the cover 120 facing the battery cell 110, although the groove position will cause the local thickness of the cover 120 to decrease, the thickness of the cover 120 near the decorative part 130 has increased. After the glue removal operation, the remaining wall thickness of the cover 120 is still sufficient to maintain the structural strength of the cover 120. The groove design of the first clearance groove 121 does not easily weaken the overall rigidity of the cover 120, and the cover 120 is not easy to bend, deform or break in daily use.

[0086] For example, a portion of the first clearance groove 121 is disposed opposite to the first surface 128, and another portion of the first clearance groove 121 is disposed opposite to the connecting surface 1271.

[0087] In the embodiments of this application, by partially removing adhesive from the projection area of ​​the piezoelectric cell 110 in the cover 120, the clearance of the cell 110 in the thickness direction of the whole device is increased, thereby reducing the impact on the cell 110. By assembling rigid foam (in this embodiment, the buffer 140 is rigid foam; in other embodiments, the buffer 140 can also be made of rubber, silicone, or other materials) in the adhesive-removed area of ​​the cover 120, the problem of pressing misalignment caused by adhesive removal is solved, and some of the impact force can be absorbed when the cover 120 deforms. Through various support schemes such as the decorative part 130 being rigidly supported to the frame 101, the decorative part 130 being glued to the bracket 160, and the decorative part 130 being supported by a small gap with the reinforcing part 182, the deformation of the decorative part 130 under drop pressure is reduced, further weakening the impact force on the battery. By using a combination of partial adhesive reduction and void-avoidance of the cover 120, rigid foam filling, and multiple supports of the decorative parts 130, the displacement of the decorative parts 130 under pressure deformation is fully reduced, and the safety gap of the battery in the thickness direction is increased. Through the structural protection measures of increasing and decreasing, the battery cell 110 is fully protected, and this solution does not affect the appearance of the cover 120.

[0088] The two sides of the adhesive removal area of ​​the cover 120 retain large flat surfaces, allowing the cover 120 to form a support with the underlying bracket 160, preventing large-area pressing misalignment. Simultaneously, the adhesive removal area features large rounded corners to effectively prevent uneven thickness marks on the cover 120's appearance. The adhesive removal feature can be directly molded, resulting in low cost for mass production.

[0089] The rigid foam needs to support the small surface area where the adhesive has sunk and cover part of the large rounded corner transition area, but it cannot exceed the outline of the mounting hole 124 of the decorative part 130 to avoid interference between the side-application adhesive at the connection between the decorative part 130 and the cover 120 and the rigid foam. Since the fiberglass cover 120 is softer than glass, pressing hard at the adhesive-sunken area can easily create play; therefore, rigid foam is used for filling. On one hand, rigid foam is much harder than conventional foam, providing support when pressing the cover 120 and improving the play problem. On the other hand, rigid foam is softer than the cover 120 and has a certain amount of compressibility, which can buffer and absorb energy when the decorative part 130 presses down on the cover 120 under strong impact. Furthermore, rigid foam is inexpensive and can be used in large quantities.

[0090] The decorative component 130 has multiple support methods around the piezoelectric cell 110 area. First, it is directly supported by the first support portion 151 on the frame 101. Second, it is supported by adhesive bonding to the bracket 160. Third, it is supported by a small gap between the decorative component 130 and the reinforcing component 182. Fourth, it is supported by the ribs on the bracket 160. Through these multiple support methods, the decorative component 130 is fully supported, reducing downward deformation during a drop and minimizing the pressure transmitted to the cell 110, thus further protecting the cell 110.

[0091] The battery is bonded to the frame 101 with double-sided adhesive. The bracket 160 is screwed to the frame 101. The partially recessed structure of the cover 120 can be directly molded, and then rigid foam is assembled. The cover 120 is bonded to the decorative part 130 with adhesive. The assembly formed by the cover 120 and the decorative part 130 is assembled to the frame 101 with double-sided adhesive, and further secured to the internal structural components of the device with applied adhesive. Figure 2 and Figure 12 As shown, the heat dissipation film 162, the wireless charging coil 163, the antenna 164, etc. are located between the cover 120 and the battery cell 110. The antenna 164 can be a near-field communication antenna.

[0092] The 120-inch cover can be directly molded using a mold, and rigid foam is a mature auxiliary material suitable for mass production. The support structure is simple and feasible. The overall protective structure design is simple, highly operable, and low-cost, does not affect the appearance of the 120-inch cover, can be used in batches, and can effectively solve the safety issues of the 110-inch battery cell caused by the 130-inch decorative part.

[0093] The electronic device 100 of this application can be a mobile phone. Of course, this solution can also be applied to other electronic products with similar designs, such as tablets and computers. The material of the cover 120 is not limited to fiberglass; it can also be a material with weak rigidity and easy deformation, such as sheet metal or plastic.
