Description

Technical Field

[0001] The present application relates to the technical field of electronic equipment, and in particular to a housing assembly and an electronic equipment. Background Art

[0002] Smart terminal devices, such as mobile phones, tablet computers, and laptops, usually need to use batteries as power sources to achieve wireless power supply and portable use. Battery safety and stability are one of the important performance indicators of smart terminal devices, because battery damage or explosion may cause device failure or user injury. In order to protect the battery, smart terminal devices usually need to be equipped with a battery cover to fix and isolate the battery to prevent the battery from external physical or environmental damage.

[0003] However, the current battery cover has some shortcomings. On the one hand, in order to improve the aesthetics and functionality of the smart terminal device, some decorative structures (DECO) are usually set on the surface of the battery cover to decorate components such as cameras, fingerprint readers, volume buttons, etc. As people have a strong demand for image photography, the decorative structures (DECO) and height dimensions of the battery cover for cameras are getting larger and larger. When the decorative structure (DECO) is subjected to external force, its edge will be squeezed into the body, which may squeeze or impact the battery, thereby damaging the structure or performance of the battery and reducing the safety and stability of the battery. On the other hand, in order to reduce the weight and thickness of the smart terminal device, the space of the battery cover is usually compact, and the gap between the battery and the battery cover is small, which also increases the risk of the battery being squeezed or impacted. At present, the conventional solution usually increases the thickness of the whole machine and fills foam and other materials between the battery cover and the battery to play a buffering role, but this solution will lead to the thickening of the whole machine, affecting the thinness and aesthetics of the whole machine. Utility Model Content

[0004] The present application provides a shell assembly and an electronic device, wherein the shell assembly is used to effectively protect a battery from being squeezed and damaged by a decorative structure without increasing the thickness of the entire device.

[0005] To achieve the above purpose, the embodiment of the present application adopts the following technical solution:

[0006] In a first aspect, a shell assembly is provided. The shell assembly is used for an electronic device. The electronic device includes a main body and a battery installed on the main body. The shell assembly can be installed on the main body and covers the battery. The shell assembly includes: a shell portion, the shell portion includes a shell body and a decorative portion formed on the shell body, the decorative portion includes a decorative protrusion formed on the outer side of the shell body, and a accommodating cavity formed on the inner side of the shell body and located inside the decorative protrusion; a protruding structure is provided on the outer side of the shell body, and an installation cavity is provided on the inner side of the shell body, the installation cavity is located inside the protruding structure, and the installation cavity is connected to the accommodating cavity; a buffer portion, the buffer portion is provided in the installation cavity, and is used to support the edge of the decorative portion.

[0007] The shell assembly provided in the embodiment of the present application can effectively protect the battery from being squeezed or damaged without increasing the thickness of the whole device, thereby increasing the battery life, reducing the battery failure rate, and improving the user experience; the setting of the decorative protrusion and the protruding structure can also increase the aesthetics and personalization of the shell assembly, improve the appearance texture of the electronic device, attract the user's attention, and enhance the user's brand awareness. Through the shell assembly of the embodiment of the present application, while protecting the battery from being squeezed by the decorative protrusion, the weight and cost of the shell assembly can be reduced, and the thinness of the shell assembly can be improved.

[0008] In one embodiment, the protrusion structure gradually protrudes from the first and second sides of the protrusion structure to the middle of the protrusion structure, and the installation cavity gradually recesses from the two sides of the protrusion structure to the middle of the protrusion structure. The strength and rigidity of the housing assembly can be increased to a certain extent, and the wear resistance and impact resistance of the housing assembly can be improved. At the same time, the depth of the installation cavity can also be increased, so that it can accommodate a thicker buffer part, thereby improving the buffering effect of the buffer part.

[0009] In one embodiment, the opposite first side and second side of the raised structure correspond to the two sides in the width direction of the electronic device respectively, and the extension direction of the raised structure is the same as the length direction of the electronic device, which is convenient for users to hold and improves the hand feel.

[0010] In one embodiment, the buffer portion includes a strip buffer member extending along the length direction of the protruding structure. By providing the strip buffer member, the elasticity and flexibility of the buffer portion can be increased, so that it can better adapt to the shape and changes of the decorative protrusion and the protruding structure, thereby improving the fit and stability of the housing assembly.

[0011] In one embodiment, one end of the buffer portion close to the decorative portion abuts against the edge of the accommodating cavity, or there is a specified spacing distance between one end of the buffer portion close to the decorative portion and the edge of the accommodating cavity. On the one hand, the embodiment of the present application directly and effectively supports the edge of the accommodating cavity by directly abutting the end of the buffer portion close to the decorative portion. In another embodiment, a specified spacing may also be set in consideration of the setting of the internal space of the mobile phone or for the protection of the buffer. The specified spacing refers to a certain distance between one end of the buffer portion close to the decorative portion and the edge of the accommodating cavity, which can be adjusted according to the size and shape of the electronic component to ensure the adaptability and buffering effect of the buffer portion.

[0012] In one embodiment, the side of the strip-shaped buffer close to the shell body is adapted to the inner wall of the installation cavity and abuts against the inner wall of the installation cavity. By providing the strip-shaped buffer, the shell assembly can effectively buffer the pressure between the edge of the decorative part and the battery, prevent the battery from being squeezed by the decorative protrusion, and improve the safety and stability of the battery. At the same time, by making the side of the strip-shaped buffer close to the shell body adapt to the inner wall of the installation cavity and abut against the inner wall of the installation cavity, the strip-shaped buffer can be firmly fixed in the shell assembly, preventing the strip-shaped buffer from shifting or falling off, and improving the structural strength and reliability of the shell assembly.

[0013] In one embodiment, the shell assembly further includes a bonding portion, which is disposed between a side of the strip buffer close to the shell body and the inner wall of the mounting cavity to adhere the strip buffer to the mounting cavity. By providing the bonding portion, the strip buffer can be more firmly adhered to the mounting cavity, preventing the strip buffer from loosening or falling off due to vibration or temperature changes during use, thereby affecting the buffering effect and structural integrity of the shell assembly. At the same time, by providing the bonding portion, the sealing between the strip buffer and the inner wall of the mounting cavity can be increased, preventing dust or moisture from entering the mounting cavity and causing pollution or corrosion to the battery, thereby improving the battery life and safety.

[0014] In one embodiment, the installation cavity is gradually recessed from the opposite sides of the protruding structure to the middle of the protruding structure to form a first inclined wall and a second inclined wall. The strip-shaped buffer is provided with a first inclined surface and a second inclined surface, the first inclined surface is arranged opposite to the first inclined wall, and the second inclined surface is arranged opposite to the second inclined wall. The shell assembly also includes a first colloid part and a second colloid part, the first colloid part is arranged between the first inclined surface and the first inclined wall, and the second colloid part is arranged between the second inclined surface and the second inclined wall. By dividing the adhesive part into two, into a first colloid part and a second colloid part, the first colloid part and the second colloid part are respectively adhered to the first inclined surface and the second inclined surface. Compared with an integrated colloid, the direct influence of various parts of the colloid during the installation of the strip-shaped buffer can be avoided, so that the connection between the strip-shaped buffer and the installation cavity is more secure.

[0015] In one embodiment, a first chamfer is provided at the bottom of the first side of the strip buffer in the width direction. By providing the first chamfer at the bottom of the first side of the strip buffer in the width direction, the strip buffer can be effectively prevented from being offset during assembly, thereby improving the assembly accuracy and quality of the housing assembly.

[0016] In one embodiment, a second chamfer is provided at the bottom of the second side of the strip buffer in the width direction. By providing the second chamfer at the bottom of the second side of the strip buffer in the width direction, the strip buffer can be effectively prevented from being offset during assembly, thereby improving the assembly accuracy and quality of the housing assembly.

[0017] In one embodiment, the buffer is made of thermoplastic polyurethane elastomer rubber. By using thermoplastic polyurethane elastomer rubber as the material of the buffer, the comprehensive performance of the housing assembly, such as wear resistance, oil resistance, water resistance, aging resistance, and weather resistance, can be improved. By using thermoplastic polyurethane elastomer rubber as the material of the buffer, the housing assembly can be easily processed and molded, thereby improving the production efficiency and quality of the housing assembly.

Specifically, the use of words such as "in one embodiment", "exemplarily", "for example", etc. is intended to present related concepts in a specific way.

[0043] In order to make the objectives, technical solutions and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0044] In the related art, smart terminal devices, such as mobile phones, tablet computers, and laptop computers, usually need to use batteries as power sources to achieve wireless power supply and portable use. Battery safety and stability are one of the important performance indicators of smart terminal devices, because battery damage or explosion may cause device failure or user injury. In order to protect the battery, smart terminal devices usually need to be equipped with a battery cover to fix and isolate the battery to prevent the battery from external physical or environmental damage.

[0045] However, the current battery cover has some shortcomings. On the one hand, in order to improve the aesthetics and functionality of the smart terminal device, some decorative structures (DECO) are usually set on the surface of the battery cover to decorate components such as cameras, fingerprint readers, volume buttons, etc. As people have a strong demand for image photography, the decorative structures (DECO) and height dimensions of the battery cover for cameras are getting larger and larger. When the decorative structure (DECO) is subjected to external force, its edge will be squeezed into the body, which may squeeze or impact the battery, thereby damaging the structure or performance of the battery and reducing the safety and stability of the battery. On the other hand, in order to reduce the weight and thickness of the smart terminal device, the space of the battery cover is usually compact, and the gap between the battery and the battery cover is small, which also increases the risk of the battery being squeezed or impacted. At present, the conventional solution usually increases the thickness of the whole machine and fills foam and other materials between the battery cover and the battery to play a buffering role, but this solution will lead to the thickening of the whole machine, affecting the thinness and aesthetics of the whole machine.

[0046] The embodiment of the present application provides a shell assembly, which is used for an electronic device, and the electronic device includes a main body and a battery 40 installed on the main body. The shell assembly can be installed on the main body and cover the battery 40, which can improve the above technical problems. It should be noted that the above electronic device refers to an Internet hardware product that has information collection, processing and connection capabilities, and can realize functions such as intelligent perception, interaction, and big data services. It is an important carrier of technologies such as the Internet and artificial intelligence, such as smart phones, tablet computers, etc.

[0047] Please refer to Figures 1 to 12 As shown, the shell assembly includes a shell part and a buffer part, the shell part includes a shell body 10 and a decorative part formed on the shell body 10, the decorative part includes a decorative protrusion 11 formed on the outer side of the shell body 10, and a receiving cavity formed on the inner side of the shell body 10 and located inside the decorative protrusion 11; the outer side of the shell body 10 is provided with a protrusion structure 12, the inner side of the shell body 10 is provided with a mounting cavity 13, the mounting cavity 13 is located inside the protrusion structure 12, and the mounting cavity 13 is connected to the receiving cavity; the buffer part is arranged in the mounting cavity 13, and is used to support the edge of the decorative part. The shell assembly is used for electronic equipment, can be installed on the main body of the electronic equipment, and cover the battery 40 of the electronic equipment, so as to protect the battery 40 from external extrusion or damage. When external force acts on the decorative protrusion 11, causing the edge of the decorative protrusion 11 to deform inwardly, the buffer part can play a buffering role, reduce the pressure on the battery 40, and improve the safety and stability of the battery 40.

[0048] It should be noted that the shell assembly refers to a shell component for an electronic device, which can be installed on the main body of the electronic device and cover the battery 40 of the electronic device to play a protective and decorative role. The shell part refers to the main part of the shell assembly, including the shell body 10 and the decorative part. The shell body 10 is the basic structure of the shell assembly, and the decorative part is the appearance part of the shell assembly, which has a decorative protrusion 11 and a receiving cavity. The decorative protrusion 11 refers to a raised part formed on the outside of the shell body 10, which has a certain height and area, can increase the aesthetics and personalization of the shell assembly, and can also increase the strength and rigidity of the shell assembly. The decorative protrusion 11 is often provided with a hollow in the middle, which is used to make way for the camera, etc. The decorative protrusion 11 mainly decorates and protects the camera, etc. The receiving cavity refers to a recessed part formed on the inner side of the shell body 10 and located inside the decorative protrusion 11, which has a certain depth and area and can accommodate the protruding parts of components such as the camera. The raised structure 12 refers to a raised portion disposed on the outside of the shell body 10, having a certain height and length, and can also increase the strength and rigidity of the shell assembly, mainly to provide sufficient installation space for the installation cavity 13 without affecting the thickness of the whole machine. The installation cavity 13 refers to a recessed portion disposed on the inner side of the shell body 10, having a certain depth and length, and located in the raised structure 12, connected to the accommodating cavity, and the buffer portion is installed to fix the buffer portion. The buffer portion refers to a buffer component disposed in the installation cavity 13, having a certain elasticity, used to support the edge of the decorative portion, and plays a buffering role, which can reduce the pressure on the battery 40 and improve the safety and stability of the battery 40.

[0049] The application scenario of the shell assembly of the embodiment of the present application is electronic devices, such as smart phones, tablet computers, laptop computers, foldable terminal devices, etc. The characteristics of these devices are that they have a strong demand for image photography, the decorative area and height of the battery 40 cover are large, and the thickness of one side of the device is very thin, which easily causes the risk of extrusion of the battery 40. Using the shell assembly of the present application, while ensuring the lightness and aesthetics of the device, the safety and stability of the battery 40 can be improved, the service life of the battery 40 can be extended, and the user experience can be enhanced.

[0050] The shell assembly of the embodiment of the present application can effectively protect the battery 40 from being squeezed or damaged without increasing the thickness of the whole device, thereby increasing the service life of the battery 40, reducing the failure rate of the battery 40, and improving the user experience; the setting of the decorative protrusion 11 and the protruding structure 12 can also increase the aesthetics and personalization of the shell assembly, improve the appearance texture of the electronic device, attract the user's attention, and enhance the user's brand awareness. Through the shell assembly of the embodiment of the present application, while protecting the battery 40 from being squeezed by the decorative protrusion 11, the weight and cost of the shell assembly can be reduced, and the thinness and economy of the shell assembly can be improved.

[0051] See also Figures 10 to 12 As shown, the protruding structure 12 of the embodiment of the present application gradually protrudes from the first side and the second side of the protruding structure 12 to the middle of the protruding structure 12, and the mounting cavity 13 gradually recesses from the two sides of the protruding structure 12 to the middle of the protruding structure 12. It should be noted that by gradually protruding the first side and the second side of the protruding structure 12 to the middle of the protruding structure 12, a structure similar to a spine protrusion can be formed, which can increase the strength and rigidity of the shell assembly to a certain extent, improve the wear resistance and impact resistance of the shell assembly, improve the drop resistance of the electronic device, and reduce the risk of damage to the electronic device. Such a structure can increase the bending rigidity of the shell portion, so that it can resist the action of external forces, and can also increase the depth of the mounting cavity 13, so that it can accommodate a thicker buffer portion, thereby improving the buffering effect of the buffer portion.

[0052] In addition, in other embodiments, the edge of the first side and the edge of the second side of the raised structure 12 are coplanar with the shell body 10. The coplanarity here is not a coplanar surface, but can also be a convex surface or a concave surface, thereby forming a relatively soft transition, avoiding problems such as stress concentration, and ensuring the grip feel.

[0053] See also Figure 1 , Figure 2 and Figure 5 As shown, in order to ensure the user's grip of the electronic device, the first and second sides of the raised structure 12 of the embodiment of the present application correspond to the two sides in the width direction of the electronic device respectively. The first and second sides of the raised structure 12 correspond to the two sides in the width direction of the electronic device respectively, that is, the width of the raised structure 12 is the same as the width of the electronic device, and the extension direction of the raised structure 12 is the same as the length direction of the electronic device, which is convenient for the user to hold and improve the hand feel. When the user holds the electronic device, he can feel the presence of the raised structure 12, but it will not affect the balance and stability of the electronic device, nor will it cause discomfort or fatigue in the hand. At the same time, the position and shape of the raised structure 12 can also be adjusted according to the user's habits and preferences to improve the user's operational convenience and satisfaction. In addition, the layout space in the length direction of the electronic device is larger than the width direction, and the raised structure 12 can be set more flexibly. The length direction of the electronic device is usually the user's line of sight direction and the main display direction of the electronic device. Therefore, setting the raised structure 12 in this direction can increase the visual effect and functionality of the electronic device. The width direction of the electronic device is usually the direction in which the user holds the device, and is also the main thickness direction of the electronic device. Therefore, providing the protruding structure 12 in this direction will affect the lightness and thinness of the electronic device and the grip feeling. Therefore, the arrangement space in the length direction of the electronic device should be larger than that in the width direction, so as to reasonably distribute and optimize the protruding structure 12.

[0054] Due to the presence of the protruding structure 12, the buffer part must satisfy the support for both the decorative part and the protruding structure 12. The buffer part of the embodiment of the present application includes a strip buffer 20, which extends along the length direction of the protruding structure 12. By providing the strip buffer 20, the elasticity and flexibility of the buffer part can be increased, so that it can better adapt to the shape and change of the decorative protruding part 11 and the protruding structure 12, thereby improving the fit and stability of the shell assembly. The strip buffer 20 is an elastic structure that can be deformed when subjected to force and return to its original shape when the force disappears, and has good buffering and vibration absorption effects. The shape and size of the strip buffer 20 can be adjusted according to the design of the mounting cavity 13 in the protruding structure 12 to achieve the best matching and support effect. In this way, when there is a certain gap or error between the shell assembly and the battery 40, the strip buffer 20 can make up for these gaps, ensure the close contact between the shell assembly and the battery 40, and prevent the shell assembly from being displaced or loosened under the action of external force, affecting the function of the shell assembly.

[0055] By extending the strip buffer 20 along the length direction of the raised structure 12, the pressure of the decorative protrusion 11 on the battery 40 can be effectively dispersed so that it is evenly distributed on the entire surface of the buffer, thereby reducing the risk of damage to the battery 40 and improving the safety and life of the battery 40. The pressure is transmitted along the length direction of the strip buffer 20 so that the pressure is evenly distributed on the area of ​​the buffer, avoiding excessive pressure at a certain point or a certain area, resulting in deformation or rupture of the battery 40. In this way, even if the decorative protrusion 11 is subjected to a large external force, it will not cause serious damage to the battery 40, ensuring the normal operation and service life of the battery 40. The material of the strip buffer 20 can be selected from some recyclable or biodegradable materials, such as thermoplastic polyurethane elastomer rubber, so that when the shell assembly is scrapped or replaced, the strip buffer 20 can be reused or processed without causing negative impact on the environment, which is in line with the concept of green environmental protection.

[0056] In addition, it should be noted that, compared with the large-area buffers in the prior art, the strip-shaped buffer 20 of the present application is more conducive to heat dissipation for electronic devices and ensures the performance of electronic devices.

[0057] See also Figure 6As shown, the end of the buffer portion of the embodiment of the present application close to the decorative portion abuts against the edge of the accommodating cavity, or there is a specified spacing distance between the end of the buffer portion close to the decorative portion and the edge of the accommodating cavity. On the one hand, the embodiment of the present application directly and effectively supports the edge of the accommodating cavity by directly abutting the end of the buffer portion close to the decorative portion. In another embodiment, a specified spacing may also be set in consideration of the setting of the internal space of the mobile phone or for the protection of the buffer. The specified spacing refers to a certain distance between the end of the buffer portion close to the decorative portion and the edge of the accommodating cavity, which can be adjusted according to the size and shape of the electronic component to ensure the adaptability and buffering effect of the buffer portion. The designated interval can also support the edge of the decorative part. The principle is as follows: when an external force acts on the decorative protrusion 11, the decorative protrusion 11 will bend inward, causing the edge of the decorative part to move inward. If there is no designated interval between the end of the buffer part close to the decorative part and the edge of the accommodating cavity, the edge of the decorative part will directly press on the buffer part, causing deformation and damage to the buffer part, affecting the buffering effect of the buffer part; if there is a designated interval between the end of the buffer part close to the decorative part and the edge of the accommodating cavity, then when an external force acts on the decorative protrusion 11, the decorative protrusion 11 will bend inward, causing the edge of the decorative part to move inward. However, due to the existence of the designated interval, the edge of the decorative part will not directly press on the buffer part, but will form an angle with the buffer part. This angle can generate a reaction force to resist the movement of the edge of the decorative part, thereby supporting the edge of the decorative part and protecting the integrity and stability of the decorative part.

[0058] See also Figures 10 to 12 As shown, the strip-shaped buffer 20 of the embodiment of the present application is adapted to the inner wall of the installation cavity 13 on the side close to the shell body 10 and abuts against the inner wall of the installation cavity 13. By providing the strip-shaped buffer 20, the shell assembly can effectively buffer the pressure between the edge of the decorative part and the battery 40, prevent the battery 40 from being squeezed by the decorative protrusion 11, and improve the safety and stability of the battery 40. At the same time, by making the strip-shaped buffer 20 close to the shell body 10 and the inner wall of the installation cavity 13 on the side close to the shell body 10, and abut against the inner wall of the installation cavity 13, the strip-shaped buffer 20 can be firmly fixed in the shell assembly, preventing the strip-shaped buffer 20 from shifting or falling off, and improving the structural strength and reliability of the shell assembly. Specifically, the provision of the strip-shaped buffer 20 can form a certain gap between the edge of the decorative part and the battery 40, thereby reducing the direct force of the decorative part on the battery 40, avoiding excessive squeezing or impact on the battery 40, causing damage or leakage of the battery 40, and affecting the normal use of the electronic device. In addition, the provision of the strip-shaped buffer member 20 can also allow a certain amount of air circulation to be formed between the edge of the decorative portion and the battery 40 , thereby improving the heat dissipation performance of the battery 40 and extending the service life of the battery 40 .

[0059] See also Figure 3 , Figure 4 , Figure 6 and Figures 10 to 12 As shown, the shell assembly of the embodiment of the present application also includes a bonding portion 30, which is arranged between the side of the strip buffer 20 close to the shell body 10 and the inner wall of the installation cavity 13, so as to adhere the strip buffer 20 to the installation cavity 13. By providing the bonding portion 30, the strip buffer 20 can be more firmly adhered to the installation cavity 13, preventing the strip buffer 20 from loosening or falling off due to vibration or temperature changes during use, affecting the buffering effect and structural integrity of the shell assembly. At the same time, by providing the bonding portion 30, the sealing between the strip buffer 20 and the inner wall of the installation cavity 13 can also be increased, preventing dust or moisture from entering the installation cavity 13, causing pollution or corrosion to the battery 40, and improving the service life and safety of the battery 40. Specifically, the setting of the adhesive portion 30 can form a layer of adhesive between the strip buffer 20 and the inner wall of the installation cavity 13. The adhesive can be a material with certain viscosity and elasticity, such as hot melt adhesive, epoxy resin, silicone, etc. The adhesive can be liquefied at a certain temperature, thereby fully filling the gap between the strip buffer 20 and the inner wall of the installation cavity 13, increasing the contact area,

[0060] The adhesive strength is improved, and when the temperature drops, the adhesive can solidify again, thereby firmly fixing the strip buffer 20 in the installation cavity 13 to prevent the strip buffer 20 from moving or falling off. In addition, the setting of the adhesive portion 30 can also form a sealing layer between the strip buffer 20 and the inner wall of the installation cavity 13, and the sealing layer can prevent external dust or moisture from entering the installation cavity 13, thereby avoiding pollution or corrosion of the battery 40 and protecting the performance and life of the battery 40.

[0061] See also Figures 10 to 12As shown, the installation cavity 13 of the embodiment of the present application is gradually recessed from the opposite sides of the protruding structure 12 to the middle of the protruding structure 12 to form a first inclined wall and a second inclined wall. The strip buffer 20 is provided with a first inclined surface and a second inclined surface, the first inclined surface is arranged opposite to the first inclined wall, and the second inclined surface is arranged opposite to the second inclined wall. The housing assembly also includes a first colloid part 31 and a second colloid part 32, the first colloid part 31 is arranged between the first inclined surface and the first inclined wall, and the second colloid part 32 is arranged between the second inclined surface and the second inclined wall. By providing the first inclined surface and the second inclined surface, the shape of the strip buffer 20 is adapted to the shape of the installation cavity 13, thereby increasing the contact area between the strip buffer 20 and the inner wall of the installation cavity 13, improving the supporting force and buffering force of the strip buffer 20, and improving the stability and heat dissipation performance of the decorative part. Specifically, the arrangement of the first inclined wall and the second inclined wall can make the cross section of the installation cavity 13 present a shape similar to the cross section of the protruding structure 12, so that the installation cavity 13 can make full use of the space of the protruding structure 12, reduce the volume of the installation cavity 13, reduce the thickness of the housing assembly, and improve the lightness and aesthetics of the electronic device. The arrangement of the first inclined surface and the second inclined surface can make the cross section of the strip buffer 20 also present a shape similar to the cross section of the installation cavity 13, so that the strip buffer 20 can fit tightly on the inner wall of the installation cavity 13, increase the contact area between the strip buffer 20 and the inner wall of the installation cavity 13, improve the support force and buffering force of the strip buffer 20, and improve the stability and heat dissipation performance of the decorative part.

[0062] Since the shape of the installation cavity 13 matches the shape of the protruding structure 12, the cross section of the installation cavity 13 presents an uneven shape, which results in uneven thickness of the inner wall of the installation cavity 13, which is thicker in some places and thinner in others. If an integrated colloid is used, then during the installation of the strip buffer 20, the colloid will be affected by the thickness difference of the inner wall of the installation cavity 13, resulting in uneven tension of the colloid, which is greater in some places and less in others. This will affect the bonding and sealing effects of the colloid, and may even cause the colloid to rupture or fall off, affecting the buffering effect and structural integrity of the shell assembly.

[0063] See also Figures 10 to 12As shown, in order to solve this problem, the embodiment of the present application divides the adhesive part 30 into two parts, namely, the first colloid part 31 and the second colloid part 32. The first colloid part 31 and the second colloid part 32 are respectively adhered to the first inclined surface and the second inclined surface. Compared with the integrated colloid, the direct influence of various parts of the colloid during the installation of the strip buffer 20 can be avoided, so that the connection between the strip buffer 20 and the installation cavity 13 is more secure. Specifically, the provision of the first colloid part 31 and the second colloid part 32 can form two independent bonding areas between the colloid and the inner wall of the installation cavity 13. The tension of each bonding area is only affected by the thickness difference of the corresponding inclined wall, but not by other parts, so that the tension of the colloid is more uniform, improving the bonding effect and sealing effect of the colloid, and at the same time preventing the colloid from breaking or falling off, ensuring the buffering effect and structural integrity of the shell assembly.

[0064] See also Fig.11 and Fig.12As shown, a first chamfer is provided at the bottom of the first side in the width direction of the strip buffer 20 of the embodiment of the present application. By providing a first chamfer at the bottom of the first side in the width direction of the strip buffer 20, it is possible to effectively prevent the strip buffer 20 from being misaligned during assembly, thereby improving the assembly accuracy and quality of the shell assembly. Misalignment refers to the position of the strip buffer 20 in the mounting cavity 13 deviating from the position required by the design, resulting in uneven gaps between the two sides of the strip buffer 20 and the inner wall of the mounting cavity 13, affecting the buffering effect of the strip buffer 20 and the sealing performance of the shell assembly. If the first chamfer is not provided, when the strip buffer 20 is misaligned, an excessively large extrusion force will be generated between the first side of the strip buffer 20 and the inner wall of the mounting cavity 13, causing deformation and damage to the strip buffer 20, and may even cause extrusion and explosion of the battery 40. If the first chamfer is provided, when the strip buffer 20 is installed deviated, due to the existence of the inclined surface of the first chamfer, the first side of the strip buffer 20 will form an angle with the inner wall of the installation cavity 13, thereby reducing the extrusion force, and at the same time, the second side of the strip buffer 20 can be tilted, so that the position of the strip buffer 20 is automatically adjusted to return to the position required by the design, ensuring the uniformity of the gap between the two sides of the strip buffer 20 and the inner wall of the installation cavity 13. By providing the first chamfer, when the first side of the strip buffer 20 is squeezed, the inclined surface of the first chamfer can be used to tilt the second side of the strip buffer 20, so that the first side of the strip buffer 20 sinks, thereby realizing the adaptive adjustment of the strip buffer 20, avoiding the excessive extrusion of the first side of the strip buffer 20, reducing the generation of local stress, and reducing the risk of battery 40 extrusion. Transition extrusion refers to the extrusion force between the first side of the strip buffer 20 and the inner wall of the installation cavity 13 exceeding the elastic limit of the strip buffer 20, resulting in permanent deformation and damage of the strip buffer 20, affecting the buffering effect of the strip buffer 20 and the sealing performance of the housing assembly. If the first chamfer is not set, when the first side of the strip buffer 20 is transitionally extruded, a gap will be generated between the second side of the strip buffer 20 and the inner wall of the installation cavity 13, resulting in uneven gaps between the two sides of the strip buffer 20 and the inner wall of the installation cavity 13, and also reducing the distance between the first side of the strip buffer 20 and the battery 40, increasing the risk of battery 40 being extruded. If a first chamfer is provided, when the first side of the strip buffer 20 is transitionally extruded, due to the existence of the inclined surface of the first chamfer, the second side of the strip buffer 20 will be lifted up, thereby causing the first side of the strip buffer 20 to sink, thereby achieving adaptive adjustment of the strip buffer 20, so that the gap between the two sides of the strip buffer 20 and the inner wall of the mounting cavity 13 remains uniform, and at the same time, the distance between the first side of the strip buffer 20 and the battery 40 remains constant, thereby reducing the risk of extrusion of the battery 40.

[0065] See also Fig.11 and Fig.12 As shown, a second chamfer is provided at the bottom of the second side in the width direction of the strip buffer 20 of the embodiment of the present application. By providing a second chamfer at the bottom of the second side in the width direction of the strip buffer 20, it is possible to effectively prevent the strip buffer 20 from being installed offset during assembly, thereby improving the assembly accuracy and quality of the shell assembly. Installation offset means that the position of the strip buffer 20 in the mounting cavity 13 deviates from the position required by the design, resulting in uneven gaps between the two sides of the strip buffer 20 and the inner wall of the mounting cavity 13, affecting the buffering effect of the strip buffer 20 and the sealing performance of the shell assembly. If the second chamfer is not provided, when the strip buffer 20 is installed offset, the second side of the strip buffer 20 will generate excessive extrusion force with the inner wall of the mounting cavity 13, causing deformation and damage to the strip buffer 20, and may even cause extrusion and explosion of the battery 40. If a second chamfer is provided, when the strip buffer 20 is installed deviated, due to the existence of the inclined surface of the second chamfer, an angle will be formed between the second side of the strip buffer 20 and the inner wall of the installation cavity 13, thereby reducing the extrusion force, and at the same time, the first side of the strip buffer 20 can be tilted, so that the position of the strip buffer 20 is automatically adjusted to return to the position required by the design, ensuring the uniformity of the gap between the two sides of the strip buffer 20 and the inner wall of the installation cavity 13. By providing the second chamfer, when the second side of the strip buffer 20 is squeezed, the inclined surface of the second chamfer can be used to tilt the first side of the strip buffer 20, so that the second side of the strip buffer 20 sinks, thereby realizing the adaptive adjustment of the strip buffer 20, avoiding the excessive extrusion of the second side of the strip buffer 20, reducing the generation of local stress, and reducing the risk of battery 40 extrusion. Transition extrusion means that the extrusion force between the second side of the strip buffer 20 and the inner wall of the installation cavity 13 exceeds the elastic limit of the strip buffer 20, resulting in permanent deformation and damage of the strip buffer 20, affecting the buffering effect of the strip buffer 20 and the sealing performance of the shell assembly. If the second chamfer is not set, when the second side of the strip buffer 20 is transitionally extruded, a gap will be generated between the first side of the strip buffer 20 and the inner wall of the installation cavity 13, resulting in uneven gaps between the two sides of the strip buffer 20 and the inner wall of the installation cavity 13, and also reducing the distance between the second side of the strip buffer 20 and the battery 40, increasing the risk of battery 40 being extruded. If a second chamfer is provided, when the second side of the strip buffer 20 is transitionally extruded, the first side of the strip buffer 20 will be lifted up due to the existence of the inclined surface of the second chamfer, thereby causing the second side of the strip buffer 20 to sink, thereby realizing adaptive adjustment of the strip buffer 20, so that the gap between the two sides of the strip buffer 20 and the inner wall of the mounting cavity 13 remains uniform, and at the same time, the distance between the second side of the strip buffer 20 and the battery 40 remains constant, thereby reducing the risk of extrusion of the battery 40.

[0066] The strip buffer 20 of the embodiment of the present application is provided with chamfers on both sides in the width direction to prevent the strip buffer 20 and the battery 40 from being damaged by the installation deviation. The above chamfers can be chamfers or rounded corners, preferably rounded corners.

[0067] The buffer part of the embodiment of the present application is made of thermoplastic polyurethane elastomer rubber. By using thermoplastic polyurethane elastomer rubber as the material of the buffer part, the comprehensive performance of the shell component such as wear resistance, oil resistance, water resistance, aging resistance, and weather resistance can be improved. By using thermoplastic polyurethane elastomer rubber as the material of the buffer part, the shell component can be easily processed and molded, thereby improving the production efficiency and quality of the shell component. Thermoplastic polyurethane elastomer rubber can be processed using common thermoplastic material processing methods.

[0068] Of course, thermoplastic polyester elastomer (TPEE) can also be used as the material of the buffer part. TPEE is a thermoplastic elastomer composed of polyester hard segment and polyether soft segment. It has the advantages of high elasticity, high strength, high toughness, wear resistance, oil resistance, water resistance, aging resistance, etc. It also has good processing performance and recyclability. Compared with TPU, TPEE has lower density, higher hydrolysis resistance and better low temperature resistance, but its high temperature resistance, chemical resistance and wear resistance are slightly inferior to TPU.

[0069] Among them, the shape of the strip buffer 20 of the embodiment of the present application can be changed to a corrugated shape, thereby increasing the elasticity and buffering force of the strip buffer 20. Specifically, the corrugated strip buffer 20 can form a certain gap between the shell body 10 and the decorative part, thereby improving the stability and heat dissipation performance of the decorative part, preventing the decorative part from being deformed or falling off due to temperature changes, affecting the aesthetics and functionality of the shell assembly. At the same time, the corrugated strip buffer 20 can produce elastic deformation when subjected to vibration or impact, thereby absorbing the impact force, improving the buffering force of the strip buffer 20, and preventing the strip buffer 20 from being damaged or falling off due to vibration or impact, affecting the buffering effect and structural integrity of the shell assembly. In addition, the corrugated strip buffer 20 can form multiple contact points with the inner wall of the installation cavity 13, thereby increasing the contact area between the strip buffer 20 and the inner wall of the installation cavity 13, improving the bonding effect and sealing effect between the strip buffer 20 and the inner wall of the installation cavity 13, preventing dust or moisture from entering the installation cavity 13, and protecting the performance and life of the battery 40.

[0070] Among them, the first inclined wall and the second inclined wall of the embodiment of the present application can be a plane or a curved surface. When the curved surface is used, the shape of the installation cavity 13 can be more consistent with the curvature of the protruding structure 12, thereby improving the space utilization rate of the installation cavity 13. At the same time, the shape of the strip buffer 20 can also be more consistent with the curved surface of the installation cavity 13, thereby improving the supporting force and buffering force of the strip buffer 20. Specifically, the curved first inclined wall and the second inclined wall can make the cross section of the installation cavity 13 present a shape that is consistent with the curvature of the protruding structure 12, so that the installation cavity 13 can fully utilize the space of the protruding structure 12, reduce the volume of the installation cavity 13, reduce the thickness of the housing assembly, and improve the lightness and aesthetics of the electronic device. At the same time, the first inclined wall and the second inclined wall of the curved surface can make the cross-section of the strip buffer 20 also present a shape that conforms to the curvature of the mounting cavity 13, so that the strip buffer 20 can fit tightly on the inner wall of the mounting cavity 13, increase the contact area between the strip buffer 20 and the inner wall of the mounting cavity 13, enhance the supporting force and buffering force of the strip buffer 20, and improve the stability and heat dissipation performance of the decorative part.

[0071] In another embodiment, a layer of thermally conductive material is disposed on the surface of the strip buffer 20, so that the strip buffer 20 can effectively conduct the heat generated by the decorative part to the shell body 10, thereby improving the heat dissipation performance of the decorative part. Specifically, the thermally conductive material can be a material with a high thermal conductivity coefficient such as graphite. The thermally conductive material can be disposed on the surface of the strip buffer 20, so that the strip buffer 20 can effectively conduct the heat generated by the decorative part to the shell body 10.

[0072] In another embodiment, a material with a self-repairing function is added to the adhesive of the adhesive part 30, so that the adhesive part 30 can automatically restore its bonding effect and sealing effect when it is damaged or aged, improve the durability and reliability of the adhesive part 30, and extend the service life of the shell assembly. Specifically, the self-repairing material can be a material with a certain self-repairing function such as a polymer with self-healing ability, nanoparticles with self-repairing ability, and microcapsules with self-repairing ability. The self-repairing material can be mixed with the adhesive of the adhesive part 30, so that the adhesive of the adhesive part 30 has a self-repairing function. When the adhesive of the adhesive part 30 is damaged or aged, the self-repairing material can automatically restore the bonding effect and sealing effect of the adhesive part 30 by physical or chemical means, improve the durability and reliability of the adhesive part 30, and extend the service life of the shell assembly. For example, the self-repairing material can be a polymer with a self-healing ability. The polymer can automatically restore the bonding effect and sealing effect of the adhesive part 30 by rearranging or cross-linking the molecular chains when it is damaged or aged. Alternatively, the self-repairing material may be a nanoparticle with self-repairing ability, which can automatically restore the bonding and sealing effects of the adhesive portion 30 through surface adsorption or reaction when damaged or aged. Alternatively, the self-repairing material may be a microcapsule with self-repairing ability, which can automatically restore the bonding and sealing effects of the adhesive portion 30 by releasing the internal repair agent when damaged or aged.

[0073] See also Figures 1 to 12 As shown, the second aspect of the present application provides an electronic device, including a main body, a battery 40 mounted on the main body, and a shell assembly, wherein the shell assembly is the above-mentioned shell assembly. Among them, the electronic device can be a smart phone, a tablet computer, a laptop computer, a foldable terminal device, etc. The characteristics of these devices are that they have a strong demand for image photography, the decorative area and height dimensions of the battery 40 cover are large, and the thickness of one side of the device is very thin, which easily causes the risk of extrusion of the battery 40. By using the shell assembly of the present application, the safety and stability of the battery 40 can be improved while ensuring the lightness and aesthetics of the device, the service life of the battery 40 can be extended, and the user experience can be enhanced.
