[0002] In today's electronic device industry, power adapters are an indispensable accessory. They are widely used in various electronic devices, such as mobile phones, tablets, laptops, game consoles, and smart home devices, providing a stable power supply to ensure their normal operation. With the increasing popularity and diversification of electronic devices, the demand for power adapters is also growing, and their performance and quality directly affect the user experience and safety of electronic devices.
[0003] Power adapters are used in a wide variety of everyday scenarios, including fixed indoor locations such as homes and offices, as well as mobile outdoor environments such as travel and business trips. In different scenarios, power adapters may be subjected to varying degrees of external forces.
[0004] For example, at home, it might be accidentally bumped to the ground or collided with other items; in the office, it might be accidentally dropped while tidying up the desk; and when carried out, it is even more likely to be squeezed or bumped, especially when mixed with other items in luggage.
[0005] Since power adapters typically consist of a housing and an internal power module, their internal structure is quite delicate. When a power adapter is subjected to external impacts such as drops, the housing and internal electronic components can easily be damaged. Therefore, designing a power adapter with an innovative structure and good drop resistance is an important research direction in the field of electronic device accessories. Utility Model Content
[0006] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the above problems.
[0007] A shock-resistant power adapter includes a housing and a power module built into the housing. The housing includes an upper cover and a lower cover that are snap-fitted together. Corner protection assemblies are respectively provided at the four corners of the housing. Each corner protection assembly includes an upper corner protector corresponding to the upper cover of the housing, a lower corner protector corresponding to the lower cover of the housing, and a connecting post connecting the upper corner protector and the lower corner protector. The upper corner protector, the connecting post, and the lower corner protector are an integral structure or an integrally connected structure.
[0008] Threaded grooves are provided along the end faces of the upper cover and the lower shell, and the upper and lower corner protectors are respectively provided with connecting holes that mate with the threaded grooves.
[0009] As a further embodiment of this utility model: the length of the connecting column is slightly shorter than the height of the shell, so that the upper corner protector can be elastically fitted onto the corner of the upper cover and the lower corner protector can be elastically fitted onto the corner of the lower shell.
[0010] As a further embodiment of this utility model: grooves are provided along the periphery of the shell, and the inner part of the connecting column is mated with the groove.
[0011] As a further embodiment of this utility model: the upper end of the connecting column extends to provide a first connecting part located inside the upper corner guard;
[0012] The lower end of the connecting post extends to a second connecting part located inside the lower corner guard.
[0013] As a further embodiment of this utility model: reinforcing posts are provided on the inner sides of the four corners of the upper cover and the lower shell, and the threaded grooves are formed on the reinforcing posts.

A plurality of protrusions are arranged at intervals around the inner wall of the upper end of the lower shell, and the plurality of protrusions are engaged with the plurality of slots one by one.
[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0016] The corner protectors are located at the four corners of the housing, allowing them to make contact with the ground first when the power adapter is dropped, absorbing most of the impact force. Through their structural design, they disperse and absorb the impact force, thereby greatly reducing the force transmitted to the main body of the housing and the internal power module, effectively reducing the possibility of housing breakage and damage to internal components.
[0017] The integrated structure or integrated connection structure of the upper corner protector, connecting post and lower corner protector, as well as the tight connection with the housing through threaded grooves and connecting holes, make the corner protector assembly and the housing an organic whole.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0029] Please see Figure 1-5In this embodiment of the present invention, a drop-resistant power adapter includes a housing 1 and a power module built into the housing 1. The housing 1 includes an upper cover 101 and a lower cover 102 that are snap-fitted together. Corner protection components 2 are respectively provided at the four corners of the housing 1. Each corner protection component 2 includes an upper corner protection 201 corresponding to the upper cover 101 of the housing 1, a lower corner protection 202 corresponding to the lower cover 102 of the housing 1, and a connecting post 203 connecting the upper corner protection 201 and the lower corner protection 202. The upper corner protection 201, the connecting post 203 and the lower corner protection 202 are an integral structure or an integral connection structure.
[0030] Threaded grooves 103 are respectively provided along the end faces of the upper cover 101 and the lower shell 102, and the upper corner protector 201 and the lower corner protector 202 are respectively provided with connecting holes 204 that cooperate with the threaded grooves 103.
[0031] The corner protection components 2 are set at the four corners of the housing 1. This is based on mechanical principles and consideration of vulnerable parts in actual use. When an object is hit or dropped, the corners are often the first to contact the ground and bear the greatest impact force. By setting the corner protection components 2 at the four corners, the external force can be effectively dispersed and absorbed, reducing the impact on the main body of the housing 1 and the internal power module.
[0032] The corner protector assembly 2 consists of an upper corner protector 201, a lower corner protector 202, and a connecting post 203. The upper corner protector 201 corresponds to the upper cover 101 of the housing 1, and the lower corner protector 202 corresponds to the lower cover 102 of the housing 1. The connecting post 203 connects the upper corner protector 201 and the lower corner protector 202 to form a complete protective structure. This design ensures that the corner protector assembly 2 can provide protection when the power adapter is dropped from any direction. The upper corner protector 201, the connecting post 203, and the lower corner protector 202 adopt an integrated structure or an integrated connection structure to ensure the strength and stability of the corner protector assembly 2 itself. The integrated structure allows the corner protector assembly 2 to transmit force evenly when subjected to external force, and will not cause structural failure due to gaps or looseness between components. If it is an integrated connection structure, such as by welding or bonding, the upper corner protector 201, the connecting post 203, and the lower corner protector 202 can be connected together, which can also ensure a certain strength while having better flexibility and adaptability, making it easier to manufacture and adjust according to different design requirements.
[0033] Threaded grooves 103 are respectively opened on the end faces of the upper cover 101 and the lower shell 102, and the upper corner protector 201 and the lower corner protector 202 are provided with connecting holes 204 that match the threaded grooves 103. This connection method realizes the tight fixation of the corner protector assembly 2 and the shell 1. The threaded connection has a certain self-locking property, which can prevent the corner protector assembly 2 from falling off due to slight vibration or external force during daily use. At the same time, the tightness of the connection between the corner protector assembly 2 and the shell 1 can be controlled by adjusting the tightening degree of the threaded connection, ensuring that the corner protector assembly 2 can effectively transfer the force to the shell 1 when subjected to external impact, and jointly bear the impact.
[0034] The upper cover 101 and lower cover 102 of the housing 1 adopt a snap-fit connection. This design not only ensures the ease of assembly of the housing 1, but also enhances the overall structural strength of the housing 1 to a certain extent. The snap-fit structure allows the upper cover 101 and lower cover 102 to form a relatively tight whole after assembly, reducing the risk of internal components being exposed and damaged due to the separation of the upper and lower parts of the housing 1 during a drop. The snap-fit housing 1 works in conjunction with the corner protection components 2 at the four corners. The corner protection components 2 provide external protection and support for the housing 1, while the snap-fit structure of the housing 1 ensures its integrity. Together, they improve the overall drop resistance of the power adapter. When the power adapter is subjected to external impact, the snap-fit housing 1 and corner protection components 2 can jointly disperse and withstand the impact force, protecting the internal power module.
[0035] Furthermore, the snap-fit connection between the upper cover 101 and the lower cover 102 of the housing 1 makes the assembly process relatively simple and quick, without the need for complicated tools and cumbersome operating steps, thus improving production efficiency. Workers can complete the assembly of the housing 1 in a short time, reducing production costs. The connection between the corner protector component 2 and the housing 1 through the threaded groove 103 and the connecting hole 204 is also relatively intuitive and easy to operate. During the assembly process, the corner protector component 2 can be accurately installed into the corresponding position of the housing 1, ensuring the firmness and accuracy of the connection.
[0036] In this embodiment of the utility model, the length of the connecting post 203 is slightly shorter than the height of the shell 1, so that the upper corner protector 201 can be elastically fitted onto the corner of the upper cover 101 and the lower corner protector 202 can be elastically fitted onto the corner of the lower shell 102.
[0037] When the connecting post 203 is slightly short, the upper corner protector 201 and the lower corner protector 202 will be subjected to a certain degree of compression after being installed on the housing 1, thus tending to undergo elastic deformation. Due to the limitation of the length of the connecting post 203, the upper corner protector 201 and the lower corner protector 202 need to overcome a certain elastic resistance during installation so that they can be tightly fitted onto the corners of the housing 1. This elastic fitting method utilizes the elastic properties of the material. When the upper corner protector 201 and the lower corner protector 202 are subjected to external forces, they can absorb and buffer some energy through their own elastic deformation. For example, when the power adapter is dropped, the corner protector that first contacts the ground will be subjected to impact force. At this time, the elastic fitting structure of the upper corner protector 201 and the lower corner protector 202 can disperse the impact force through deformation, reducing the force transmitted to the housing 1 and the internal power module. At the same time, this elastic deformation can also provide a certain restoring force, so that the corner protector can quickly return to its original shape after being impacted, continuing to provide protection for the power adapter.
[0038] Furthermore, the elastic fitting of the upper corner protector 201 and the lower corner protector 202, together with the other parts of the corner protector assembly 2 and the housing 1, constitutes an organic whole protection system. When subjected to external impact, the elastic fitting structure allows the corner protectors to fit more tightly against the corners of the housing 1, increasing the contact area and thus more effectively dispersing the impact force. In addition, under normal use, the elastically fitted upper corner protector 201 and lower corner protector 202 can restrain the corners of the housing 1 to a certain extent, enhancing the overall structural stability of the housing 1. This restraining force can prevent the housing 1 from deforming or being damaged at the corners when subjected to slight external forces, thus improving the durability of the power adapter.
[0039] In this embodiment of the utility model, groove positions 104 are respectively provided along the periphery of the shell 1, and the inner part of the connecting post 203 is mated with the groove positions 104.
[0040] During the manufacturing process, the design of the groove 104 and the connecting post 203 can provide a certain reference and positioning for the production process. By precisely machining the size and shape of the groove 104 and the connecting post 203, the precision and consistency of the manufacturing process can be improved, ensuring that the corner protector assembly 2 of each power adapter can achieve a good mating fit with the housing 1. From the perspective of space utilization, mating the inner part of the connecting post 203 with the groove 104 on the periphery of the housing 1 can make the combination of the corner protector assembly 2 and the housing 1 more compact, reducing the space occupied by the overall structure.
[0041] By mating the groove 104 with the inner part of the connecting post 203, the impact force can be more effectively transferred from the corner protector 2 to the periphery of the housing 1 and dispersed on the periphery. This optimized force transmission and dispersion method greatly reduces the possibility of excessive local stress on the housing 1 when it is impacted, and further improves the drop resistance of the power adapter.
[0042] In this embodiment of the utility model, the upper end of the connecting post 203 is provided with a first connecting part 205 located inside the upper corner guard 201;
[0043] The lower end of the connecting post 203 extends to provide a second connecting part 206 located inside the lower corner guard 202.
[0044] A first connecting part 205 extends from the upper end of the connecting post 203 and is located inside the upper corner protector 201, while a second connecting part 206 extends from the lower end and is located inside the lower corner protector 202. This design is to enhance the overall integrity and stability of the connection between the corner protector assembly 2 and the connecting post 203. Through the extended first connecting part 205 and second connecting part 206, the connection between the upper corner protector 201, the lower corner protector 202 and the connecting post 203 is not limited to the contact of the corners, but forms a deeper integration inside. From a mechanical point of view, when the power adapter is subjected to external impact, the corner protector assembly 2 needs to effectively transfer the force to the connecting post 203. This extended connecting part provides a larger contact area and a more solid connection point, so that the force can be distributed and transferred more evenly, reducing the risk of damage to the connection part due to excessive local stress.
[0045] In this embodiment of the utility model, reinforcing posts 105 are provided on the inner sides of the four corners of the upper cover 101 and the lower shell 102, and the threaded grooves 103 are provided on the reinforcing posts 105.
[0046] The threaded groove 103 is formed on the reinforcing post 105, so that the connection point between the corner protector assembly 2 and the housing 1 directly acts on the reinforcing post 105. In this way, when tightening the screws of the corner protector assembly 2, the force can be transmitted to the reinforcing post 105 more evenly, giving full play to the reinforcing effect of the reinforcing post 105 and avoiding damage caused by local stress concentration in thinner parts of the housing 1. At the same time, by setting the reinforcing post 105 at these key positions, the local structural strength of the housing 1 can be effectively enhanced, and its ability to resist deformation and cracking can be improved.
[0047] In this embodiment of the present invention, a plurality of connecting blocks 106 are arranged at intervals extending around the lower inner side of the upper cover 101. A slot 107 is provided on one side of the connecting block 106. A plurality of protrusions 108 are arranged at intervals around the upper inner wall of the lower shell 102. The plurality of protrusions 108 are engaged with the plurality of slots 107 one by one.
[0048] This design forms an interlock-like structure. When assembling the power adapter housing 1, the protrusion 108 can be accurately inserted into the corresponding slot 107 of the connecting block 106, achieving initial connection and positioning between the upper cover 101 and the lower housing 102. The threaded groove 103 around the end faces of the upper cover 101 and the lower housing 102, as well as the connecting hole 204 on the corner protector assembly 2, are connected by screws. This connection method mainly provides the vertical clamping force between the housing 1 and the corner protector assembly 2, while the snap-fit structure between the connecting block 106 and the protrusion 108 enhances the connection stability between the upper cover 101 and the lower housing 102 in the horizontal direction. The two connection methods complement each other, giving the power adapter housing 1 good connection strength and stability in all directions. In actual use, whether subjected to vertical pressure or horizontal impact, the power adapter can maintain good structural integrity, thereby effectively protecting the internal power module.
[0049] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
