[0009] In some embodiments, the housing is provided with a first mounting groove at the corner, and the first buffer is disposed in the first mounting groove.

[0010] In some embodiments, the housing is provided with a positioning hole communicating with the first mounting groove, and the first buffer member is provided with a positioning block protruding along the direction of insertion into the first mounting groove.

[0016] In some embodiments, the photographic equipment power supply device further includes:

[0017] At least one heat sink is disposed on the side surface of the housing near the power supply component.

[0018] In some embodiments, the surfaces of the plurality of first buffer members are provided with first anti-slip portions; and / or,

[0019] The surfaces of the plurality of second buffer members are provided with second anti-slip portions.

[0020] In some embodiments, the plurality of first cushioning elements are fixedly bonded to the corners of the housing by an adhesive; and / or,

[0021] The plurality of second buffer components are fixedly bonded to the edges of the housing by adhesive.

[0022] In some embodiments, the first buffer, the second buffer, and the third buffer are all made of an elastic material.

[0023] In some embodiments, at least one of the first buffer, the second buffer, and the third buffer is integrally formed with the housing.

[0024] In some embodiments, the power supply assembly includes a bracket, a plurality of batteries, and a control circuit board. The bracket is housed within the receiving cavity and is fixedly connected to the housing. The plurality of batteries and the control circuit board are respectively disposed on the bracket, and the plurality of batteries are electrically connected to the control circuit board.

[0025] The control circuit board is connected to an output interface exposed outside the housing, and the output interface is integrally formed with the housing.

When the power supply device is accidentally dropped, the first buffer located at the corner of the housing contacts the ground or obstacle first. Through its elastic deformation, the first buffer disperses and absorbs the impact force, reducing the impact intensity at the corner. Simultaneously, the second buffer located at the edge further mitigates the transmission of impact force into the housing by utilizing its own buffering properties. This multi-layered buffering mechanism prevents impact force from directly acting on the internal power supply components, effectively reducing the risk of damage to the device due to accidental drops, thereby extending the overall service life of the power supply device.

[0047] Please refer to Figure 1This application provides a power supply device 100 for photographic equipment, including a housing 10, a power supply component, and a buffer structure 20. The housing 10 has an internal cavity, and the outer surface of the housing 10 has edges 11 and corners 12. The power supply component is disposed in the cavity and is used to provide power to the photographic equipment. The buffer structure 20 includes a plurality of first buffers 21 and a plurality of second buffers 22. The plurality of first buffers 21 are respectively disposed at the corners 12 of the housing 10, and the plurality of second buffers 22 are respectively disposed at the edges 11 of the housing 10.

[0048] The housing 10, serving as the external protective structure of the power supply device 100 for photographic equipment, is a polyhedral structure formed by multiple planes, creating a cavity to house the power supply components and provide physical protection against external environmental interference and damage. Simultaneously, the edges 11 and corners 12 of the housing 10 disperse impact forces in various directions when the device is subjected to impact, while the buffer structure 20, located in these critical areas, more effectively absorbs and buffers energy.

[0049] The power supply component is located inside the housing cavity. Its main function is to provide a stable power supply for photographic equipment, ensuring that photographic equipment such as cameras and fill lights can work normally and meet the power needs during the shooting process.

[0050] Multiple first buffers 21 are respectively disposed at the corners 12 of the housing 10. The corners 12 are the parts of the device most susceptible to direct impact when dropped or collided. The first buffers 21 can preferentially withstand the impact force at these locations and absorb and disperse the energy through their own elastic deformation, reducing the transmission of the impact force to the power supply components inside the housing 10 and protecting the power supply components from damage.

[0051] Multiple second buffers 22 are respectively disposed at the edges 11 of the housing 10. The edges 11 are also an important energy transfer path when the device is impacted. The second buffers 22 can further buffer and absorb the impact force at the edges 11, working together with the first buffer 21 to form a comprehensive buffer protection system, enhancing the overall shock absorption performance of the device.

[0052] When the power supply device is accidentally dropped, the first buffer 21, located at the corner 12 of the housing 10, makes contact with the ground or obstacle first. Through its elastic deformation, the first buffer 21 disperses and absorbs the impact force, reducing the impact intensity at the corner 12. Simultaneously, the second buffer 22, located at the edge 11, further mitigates the transmission of the impact force into the housing 10 by utilizing its own buffering characteristics when the impact force reaches the edge 11. This multi-layered buffering mechanism prevents the impact force from directly acting on the internal power supply components, effectively reducing the risk of damage due to accidental drops and thus extending the overall service life of the power supply device.

[0053] Please refer to Figure 2 In some embodiments, the housing 10 is provided with a first mounting groove 13 at the corner 12, and the first buffer member 21 is disposed in the first mounting groove 13.

[0054] The function of the first mounting groove 13 is to position and fix the first buffer 21, ensuring that the first buffer 21 is accurately positioned on the housing 10 so that it can stably perform its buffering function when the device is subjected to impact. At the same time, the structure of the first mounting groove 13 can also provide a certain degree of protection and constraint for the first buffer 21, preventing it from shifting or falling off when subjected to impact, thus ensuring the reliability of the buffering function.

[0055] In this embodiment, the fixing effect of the first mounting groove 13 on the first buffer member 21 enhances the stability of the entire buffer structure 20. When the device is impacted, the first buffer member 21 will not be affected by shaking or displacement, and can always maintain its optimal position to play its role, thereby improving the reliability and consistency of the device's anti-drop and shock absorption performance.

[0056] Please refer to Figure 2 and Figure 3 In some embodiments, the housing 10 is provided with a positioning hole 14 communicating with the first mounting groove 13, and the first buffer member 21 is provided with a positioning block 211 protruding along the direction of insertion into the first mounting groove 13. The positioning block 211 is used to engage with the positioning hole 14 to fix the first buffer member 21 at the corner 12 of the housing 10.

[0057] The positioning hole 14 is connected to the first mounting groove 13. Its main function is to provide a locking position for the positioning block 211. Through the interaction with the positioning block 211, the first buffer 21 is fixed, ensuring the accurate installation position of the first buffer 21 on the housing 10. When the device is impacted, the movement of the first buffer 21 is restricted, so that it can stably play a buffering role.

[0058] A positioning block 211 is disposed on the first buffer member 21 and protrudes along the direction of insertion into the first mounting groove 13. Its function is to cooperate with the positioning hole 14 to fix the first buffer member 21 at the corner 12 of the housing 10. During installation, the positioning block 211 guides the first buffer member 21 to be accurately inserted into the first mounting groove 13, and after being in place, it engages with the positioning hole 14 to prevent the first buffer member 21 from loosening or falling off. When the device is subjected to external impact, the positioning block 211 can withstand a certain amount of tensile and shear forces, maintaining the stable position of the first buffer member 21 and ensuring the buffering effect.

[0059] When installing the first buffer member 21, it is pushed along the direction of insertion into the first mounting groove 13. At this time, the positioning block 211 on the first buffer member 21 will gradually move closer to the positioning hole 14 as the first buffer member 21 is inserted. When the first buffer member 21 is fully inserted into the first mounting groove 13, the positioning block 211 is exactly aligned with the positioning hole 14 and locked in there. Through the locking cooperation between the positioning block 211 and the positioning hole 14, the first buffer member 21 is fixed at the corner 12 of the housing 10.

[0060] In this embodiment, the locking mechanism between the positioning block 211 and the positioning hole 14 provides reliable fixation for the first buffer 21, making the installation of the first buffer 21 on the housing 10 more secure and less prone to loosening or falling off. Even when the device is subjected to strong impact or vibration, the first buffer 21 can remain in the correct position and continuously and effectively perform its buffering function, greatly improving the device's shock absorption and anti-drop performance.

[0061] In some embodiments, the housing 10 is provided with a second mounting groove 15 along the extending direction of the edge 11, and the second buffer member 22 is disposed in the second mounting groove 15.

[0062] The main function of the second mounting groove 15 is to provide a precise installation position and fixed support for the second buffer 22. Its placement along the extension direction of the edge 11 allows the second buffer 22 to be distributed along the main path of impact force transmission, ensuring that the second buffer 22 can effectively perform its buffering function when the device is impacted. Simultaneously, the second mounting groove 15 limits and protects the second buffer 22, preventing it from shifting or falling off when impacted.

[0063] In this embodiment, the second mounting groove 15 provides a stable installation environment for the second buffer 22, making it less prone to displacement or detachment when the device is subjected to impact. This ensures that the second buffer 22 can continuously and effectively perform its buffering function, enhancing the reliability and stability of the device. Furthermore, installing the second buffer 22 within the second mounting groove 15 is simple and convenient, reducing installation difficulty and improving production efficiency. When the second buffer 22 is damaged and needs replacement, it is also easy to disassemble and install a new buffer, reducing maintenance costs and time, and improving the maintainability of the device.

[0064] In some embodiments, the buffer structure 20 further includes a plurality of third buffer members 23, which are respectively disposed on the surface of the housing 10.

[0065] The third buffer 23, being the component directly in contact with external impacts, primarily functions to absorb and buffer the impact force acting on the surface of the housing 10. Utilizing its elastic properties, the third buffer 23 deforms under external force, dissipating impact energy and reducing the amplitude of vibration transmitted into the housing 10, thereby protecting the power supply components. Furthermore, the third buffer 23 can also disperse impact force to a certain extent, preventing excessive localized stress from damaging the housing 10.

[0066] When the power supply unit 100 of the photographic equipment is subjected to external forces, such as collisions or drops, the impact force will not only act on the corners 12 and edges 11 of the housing 10, but the surface of the housing 10 will also bear a certain amount of impact force. Multiple third buffers 23 are disposed on the surface of the housing 10. When subjected to impact, the third buffers 23 will come into contact with the external object and undergo elastic deformation. Through this elastic deformation, the third buffers 23 absorb the energy brought by the impact force, converting it into their own elastic potential energy, thereby reducing the intensity of the impact force transmitted into the housing 10 and protecting the power supply components inside the housing 10 from damage.

[0067] In this embodiment, the third buffer 23, together with the first buffer 21 and the second buffer 22 located at the corner 12 and the edge 11, forms all-round protection for the housing 10. Regardless of the direction of the impact, the corresponding buffer will absorb and buffer it, greatly improving the device's ability to resist impacts under various conditions and better protecting the internal power supply components.

[0068] In some embodiments, the third buffer 23 has a plate-like structure;

[0069] The housing 10 has a cuboid structure, and multiple third buffers 23 are respectively disposed on the opposite surfaces of the housing 10.

[0070] Among them, the plate-shaped third buffer 23 has a larger contact area, which can more effectively disperse the impact force and has higher efficiency in absorbing impact energy compared with other shapes of buffers. Multiple third buffers 23 are arranged on opposite surfaces of the housing 10 to buffer and protect the housing 10 from different directions, further enhancing the buffering effect and better protecting the internal power supply components.

[0071] In this embodiment, the rectangular shell 10, combined with the plate-shaped third buffer 23, forms a relatively regular overall structure with good stability. The plate-shaped third buffer 23 is not prone to displacement or deformation during installation and use, ensuring a continuous and stable buffering effect. Simultaneously, this structural design facilitates installation and fixation during production, improving production efficiency and product quality.

[0072] During the process of providing power to photographic equipment, the power supply components generate heat due to factors such as energy conversion and internal resistance. When too much heat accumulates, it will affect the performance and lifespan of the power supply components.

[0073] In order to extend the service life of the power supply components, in some embodiments, the photographic equipment power supply device 100 further includes at least one heat sink 30 disposed on the side surface of the housing 10 near the power supply components.

[0074] The primary function of the heat sink 30 is heat dissipation. It can be made of various materials and is used to dissipate heat from the device. Commonly used heat sinks 30 are made of metal, such as copper, which has excellent thermal conductivity and can quickly conduct heat. The heat sink 30 absorbs the heat generated by the power supply components through indirect contact and transfers the heat to the surrounding environment. The large surface area of ​​the heat sink 30 increases the contact area with the air, which is conducive to heat convection and accelerates heat dissipation. At the same time, its good thermal conductivity allows heat to be quickly transferred from the power supply components to the surface of the heat sink 30, improving heat dissipation efficiency. Furthermore, the heat sink 30 can also, to some extent, even out the temperature of the power supply components' surface, preventing localized overheating.

[0075] In this embodiment, the heat sink 30 is disposed on the surface of the housing 10 near the power supply component. The heat generated by the power supply component can be transferred to the heat sink 30 through thermal conduction. The heat sink 30 typically has a large surface area and good thermal conductivity, which can quickly dissipate the absorbed heat into the surrounding environment. It can reduce its own temperature through thermal convection and thermal radiation, thereby achieving heat dissipation for the power supply component, ensuring that the power supply component operates within a suitable temperature range, slowing down the aging rate of components, and extending the service life of the power supply component and the entire photographic equipment power supply device 100.

[0076] In addition, the heat sink 30, through its material and structural design, provides reinforced protection for the device in the event of a drop. When the device is accidentally dropped, the heat sink 30 absorbs part of the impact force and distributes it throughout the housing 10 through its structure. The robust material of the heat sink 30 effectively buffers the impact force, preventing damage to the internal power supply components due to stress concentration. Its stable connection with the housing 10 further enhances the overall structural strength.

[0077] In some embodiments, the surfaces of the plurality of first buffer members 21 are provided with first anti-slip portions 212; and / or,

[0078] The surfaces of multiple second buffer members 22 are provided with second anti-slip parts 221.

[0079] The first anti-slip portion 212 is disposed on the surface of the plurality of first buffer members 21, and its main function is to increase the friction between the first buffer member 21 and the contact surface. When the device is placed on a flat surface or held, the first anti-slip portion 212 can effectively prevent the device from sliding due to external force or its own weight, improving the stability of the device during placement and use. At the same time, when the device is subjected to impact, the first anti-slip portion 212 can also help the first buffer member 21 to be better fixed at the corner 12 of the housing 10, preventing the first buffer member 21 from shifting under the action of impact force.

[0080] The second anti-slip portion 221 is located on the surface of the plurality of second buffer members 22 and functions similarly to the first anti-slip portion 212. It prevents the device from sliding in contact scenarios related to the edge 11 by increasing friction with the contact surface. For example, when the device is placed on a support surface with a certain angle of inclination, the second anti-slip portion 221 can help the device remain more stably in that position. Furthermore, when the device is subjected to external impact, the second anti-slip portion 221 helps the second buffer member 22 remain stable within the second mounting groove 15, enhancing the overall reliability of the buffer structure 20.

[0081] In this embodiment, the first anti-slip part 212 and the second anti-slip part 221 improve the stability of the photographic equipment power supply device 100 during placement and use. Whether placed on a flat surface or held, they effectively prevent the device from sliding or falling, reducing accidental damage that may be caused by device movement, and providing a more reliable power supply for photographic work.

[0082] It should be understood that the first anti-slip portion 212 and the second anti-slip portion 221 may have textures such as horizontal lines, vertical lines, diagonal lines, or diamond patterns processed on the surface of the corresponding buffer element. These textures increase the friction with the contacting object, thereby preventing the device from sliding. Alternatively, raised particles of hemispherical or conical shapes may be evenly distributed on the surface of the corresponding buffer element, which both prevents slippage and buffers and disperses pressure during impact. Of course, the above are merely exemplary, and the embodiments of this application are not limited herein.

[0083] In some embodiments, a plurality of first buffer members 21 are fixedly bonded to the corners 12 of the housing 10 by adhesive; and / or,

[0084] Multiple second buffers 22 are fixedly bonded to the edges 11 of the housing 10 with adhesive.

[0085] The adhesive's viscosity ensures a tight bond between the first buffer 21 and the corner 12 of the housing 10, and between the second buffer 22 and the edge 11 of the housing 10. Intermolecular forces, such as van der Waals forces and hydrogen bonds, are generated between the adhesive molecules and the molecules of the buffer and housing materials, forming a strong connection. When the device is subjected to external impact, this connection resists the impact force, keeping the buffer in its predetermined position and continuously providing cushioning.

[0086] In this embodiment, the adhesive provides strong adhesion, which makes the buffer tightly bonded to the housing 10. When the device is subjected to multiple impacts or vibrations, the buffer is not easy to loosen or fall off, thus ensuring the reliability of the buffer structure 20.

[0087] Of course, besides adhesives, various other methods can be used to fix the buffer to the housing 10. For example, bolted connections rely on threaded holes in both, and are tightened with bolts and nuts for a secure connection. The embodiments described in this application are not limited to these specific methods.

[0088] Similarly, the third buffer 23 and the heat sink 30 can also be fixedly bonded to the housing 10 with adhesive. After being fixed with adhesive, it is ensured that they can be firmly attached to the surface of the housing 10 when subjected to impact, so as to continue to perform their respective functions.

[0089] In some embodiments, the first buffer 21, the second buffer 22, and the third buffer 23 are all made of elastic material.

[0090] Elastic materials possess unique mechanical properties. When the first buffer 21, the second buffer 22, and the third buffer 23 are subjected to external impact, the molecular chains within the material undergo stretching, twisting, and other deformations. After the external force disappears, the molecular chains quickly return to their initial state, a process that achieves the absorption and release of impact energy. When the photographic equipment power supply device 100 is subjected to a collision or drop, the three buffers, based on the properties of elastic materials, convert the impact energy into elastic potential energy through their own deformation, effectively reducing the impact force transmitted to the interior of the housing 10, thereby protecting the power supply components.

[0091] In this embodiment, the elastic material gives the buffer a good buffering capacity, which greatly reduces the probability of damage to the power supply components when the device is impacted, extends the service life of the power supply device, and ensures that the photographic equipment can obtain a stable power supply in various complex environments.

[0092] Commonly used elastic materials for making cushioning components include rubber, silicone, and polyurethane. Rubber is inexpensive and has good elasticity; natural rubber and nitrile rubber have excellent wear resistance and weather resistance. Silicone is chemically stable, possesses insulating and high-temperature resistant properties, and is soft in texture. Polyurethane, on the other hand, has high strength and combines elasticity and wear resistance. They can meet the performance requirements of cushioning components in different scenarios.

[0093] In some embodiments, at least one of the first buffer member 21, the second buffer member 22, and the third buffer member 23 is integrally formed with the housing 10.

[0094] This embodiment employs injection molding and compression molding processes to directly manufacture each buffer component and the housing 10 as a single unit. Through material fusion and structural continuity, it eliminates the connection gaps of traditional assembled buffer structures, preventing buffer components from detaching or shifting due to vibration and impact, and extending the protection life of the power supply device 100. Moreover, this design allows impact forces to be dispersed through a continuous material transmission path, preventing buffer failure caused by loosening or detachment between components. At the same time, it utilizes the anisotropic properties of materials to optimize the mechanical performance matching between the buffer components and the housing 10 during the molding process.

[0095] Please refer to Figures 4 to 6 In some embodiments, the power supply assembly 40 includes a bracket 41, a plurality of batteries 42 and a control circuit board 43. The bracket 41 is housed in a receiving cavity and is fixedly connected to the housing 10. The plurality of batteries 42 and the control circuit board 43 are respectively disposed on the bracket 41, and the plurality of batteries 42 are electrically connected to the control circuit board 43.

[0096] The control circuit board 43 is connected to an output interface 431 exposed outside the housing 10, and the output interface 431 is integrally formed with the housing 10.

[0097] In this embodiment, the bracket 41 serves as the core support structure of the power supply component 40, providing a mounting carrier for the battery 42 and the control circuit board 43. The bracket 41 is fixedly connected to the housing 10, forming a stable internal mechanical support system to prevent internal components from shifting or colliding under vibration or external force, thus ensuring the stability of the relative positions of each component.

[0098] Multiple batteries 42 are combined in series or parallel to form an energy storage unit, providing continuous power to photographic equipment. The batteries 42 are electrically connected to the control circuit board 43, and the charging and discharging process is realized under the management of the control circuit board 43 to meet the power requirements of different devices.

[0099] The control circuit board 43 is responsible for monitoring the status of the battery 42 (such as charge, voltage, and temperature), performing charge and discharge protection (overcharge, over-discharge, overcurrent, and short circuit protection), and converting and regulating the electrical energy of the battery 42 before stably outputting it to external devices through the output interface 431.

[0100] The output interface 431 serves as the connection hub between the power supply device 100 and the photographic equipment. It is integrally formed with the housing 10, allowing it to directly obtain the rigid support of the housing 10 structure, thus avoiding the loosening and damage caused by external force pulling of traditional embedded interfaces. At the same time, the integral forming process eliminates the gap between the output interface 431 and the housing 10, improving waterproof and dustproof performance and ensuring stable power transmission.

[0101] In some embodiments, the photographic equipment power supply device 100 further includes a waterproof sealing cover 50 for sealing the output interface 431.

[0102] The waterproof sealing cover 50 can be tightly fastened to the edge of the output interface 431 by means of snaps, threads or magnetic attraction. When the output interface 431 is not in use, it covers the surface of the output interface 431 to form a sealed space, preventing sharp objects from scratching the metal contacts of the interface, avoiding deformation and damage to the interface due to external impact, extending the service life of the output interface 431, and blocking the intrusion path of foreign objects such as moisture and dust. Together with the output interface 431 integrally formed with the housing 10, it further enhances the overall protection performance.

[0103] In some embodiments, the bracket 41 is fixedly connected to the housing 10 by a snap or screw.

[0104] The inner wall of the housing 10 can be provided with protruding hooks or grooves, and the bracket 41 is designed with matching barbs or grooves at corresponding positions. By pressing or sliding, the buckling components can be interlocked to form a locked state, enabling tool-free quick installation and improving production assembly efficiency. The engagement gap can absorb slight vibrations through elastic deformation, reducing stress concentration caused by rigid connection.

[0105] The housing 10 and the bracket 41 have pre-drilled screw holes. Screws (such as Phillips head screws or countersunk screws) are passed through the screw holes and tightened. The relative position of the two is fixed by the friction of the threads, providing high-strength connection stability. It is suitable for scenarios that need to withstand large impacts or vibrations. The removable screw feature facilitates later maintenance and component replacement.

[0106] In this embodiment, the bracket 41 is rigidly connected to the housing 10 by the elastic engagement of the buckle or the mechanical fastening of the screw. The buckle structure achieves quick installation by relying on the interlocking of geometric shapes, while the screw connection provides continuous fastening force through the thread engagement. Both methods can ensure that the bracket 41 is fixed in position within the receiving cavity, preventing internal components from shaking.

[0107] Please continue to refer to this. Figure 6 In some embodiments, the bracket 41 is provided with a plurality of mounting cavities 411, which are arranged in a matrix array on the bracket 41, and each battery 42 is mounted in one mounting cavity 411; and / or,

[0108] An installation space is provided between one side of the bracket 41 and the inner wall of the housing 10. A support plate 413 is provided on the side of the bracket 41 facing the installation space. The control circuit board 43 is located in the installation space and is fixedly connected to the support plate 413.

[0109] Multiple independent mounting cavities 411 are regularly arranged on the surface of the bracket 41. Each mounting cavity 411 is precisely adapted to the size of a single battery 42, ensuring that the battery 42 is securely embedded. The matrix mounting cavities 411 enable high-density arrangement of the batteries 42, increasing the energy storage capacity per unit volume.

[0110] One side of the bracket 41 forms a sandwich-type installation space with the inner wall of the housing 10. The support plate 413 extends from the surface of the bracket 41 toward the space. The control circuit board 43 is fixed to the plate by screws or thermal adhesive to achieve suspended installation, physically isolating the battery 42 from the circuit board, preventing the heat generated by the battery 42 from affecting the circuit components, reducing the contact area between the circuit board and the bracket 41, and reducing the vibration transmission efficiency.

[0111] In this embodiment, the bracket 41 achieves the orderly integration of the battery 42 and the control circuit board 43 through a matrix-type mounting cavity 411 and a layered mounting space design. The matrix array disperses and fixes multiple batteries 42, reducing the impact of individual vibrations; the layered layout utilizes spatial differences to independently install the control circuit board 43, avoiding direct contact with the battery 42, while the support plate 413 enhances structural rigidity, ensuring that internal components achieve functional isolation and collaboration within a limited space.

[0112] Please continue to refer to this. Figure 5In some embodiments, the housing 10 includes a left half-shell 101, a right half-shell 102 and a top shell 103. The left half-shell 101 and the right half-shell 102 are arranged opposite to each other and spliced ​​together to form a receiving cavity. One end of the receiving cavity is closed and the other end is open 104. The top shell 103 covers the open 104.

[0113] Among them, sealing rings 105 are provided between the left half shell 101 and the right half shell 102, and between the top shell 103 and the opening 104.

[0114] The left half-shell 101 and the right half-shell 102 form the main components of the receiving cavity. When spliced ​​together, they create a stable three-dimensional space, providing a mounting base for the internal power supply component 40. Precise splicing is achieved through pre-set clips, grooves, or screw holes, ensuring structural strength and positional stability.

[0115] The top shell 103 covers the opening 104 of the receiving cavity, forming a complete enclosed space together with the left half shell 101 and the right half shell 102, protecting the internal components from external physical damage; at the same time, the surface of the top shell 103 can integrate functional components such as output interface 431 and switch for user convenience.

[0116] The sealing rings 105 are respectively set at the joint of the left half shell 101 and the right half shell 102, and at the edge of the top shell 103 and the opening 104. They are squeezed and deformed during component assembly, tightly fitting the connecting surface, eliminating gaps, preventing moisture and dust from entering the interior of the shell 10, and ensuring the safe and stable operation of the power supply component 40.

[0117] In this embodiment, the housing 10 is constructed by splicing the left half-shell 101 and the right half-shell 102 to form the main body of the receiving cavity, and the split design of the top shell 103 closing the opening 104 is achieved through mechanical splicing. Sealing rings 105 are embedded at the joints of each component, and the compression deformation of elastic materials such as rubber is used to fill the splicing gaps, block the intrusion path of foreign objects such as moisture and dust, form a physical sealing barrier, and improve the protection performance of the power supply device 100.

Those skilled in the art can make other variations or modifications based on the above description. It is impossible to exhaustively list all possible implementations here.
