Description

Technical Field

[0001] This utility model relates to the field of mobile power supply technology, and in particular to a mobile power supply housing structure. Background Technology

[0002] A portable power bank, also known as a power bank, is a portable charging device that integrates power supply and charging functions. It typically uses a lithium-ion battery as its energy storage medium and is mainly used to charge portable electronic products (such as mobile phones and laptops) in situations where no external power supply is available. A typical portable power bank consists of a battery (block), a protection circuit board, a casing material, a thermistor, and a PTC (Power Transmitter) chip.

[0003] The existing power bank casing structure has the following drawbacks: 1. The openings of the upper and lower casings are prone to misalignment, making assembly inconvenient; 2. The battery installation inside the casing is not stable or reliable enough, and its movement within the casing is not well restricted; furthermore, the installation and fixation of the circuit board with the charging interface is not reliable enough. After repeated insertion and removal, the circuit board shifts, causing the charging interface to shift and making charging inconvenient; 3. The casing has a clearance opening for the insertion of the charging and discharging interface, but this opening lacks a protective cover. When not in use, the charging and discharging interface is open, allowing dust to easily enter and affecting the reliability of the charging and discharging connection.

[0004] Therefore, how to provide a mobile power supply housing structure with a simpler and more reasonable structural design, easier assembly, better installation and fixation of internal components, and better prevention of dust from entering the housing has become a technical problem to be solved by those skilled in the art. Utility Model Content

[0005] In view of the above-mentioned defects of the prior art, the technical problem to be solved by this utility model is how to provide a mobile power supply housing structure with a simpler and more reasonable structural design, which can be more convenient to assemble, can better install and fix the internal components, and can better prevent dust from entering the housing.

[0006] To achieve the above objectives, this utility model provides a mobile power supply housing structure, including a rectangular box-shaped housing. An installation space is formed inside the housing, and electrical components are installed thereon. The electrical components include a charging / discharging interface, and the housing has an opening for the outer end of the charging / discharging interface to be inserted and fitted. The housing is characterized by: a lower housing with a rectangular box-shaped structure and an open upper end, connected by a connecting structure to an upper housing with a rectangular box-shaped structure and an open lower end, located at the open end of the lower housing; the connecting structure includes connecting posts arranged longitudinally at intervals on both sides of the bottom surface inside the lower housing; vertically downward-facing docking posts are provided on the bottom surface inside the upper housing, corresponding to each connecting post, with the upper end of the connecting post inserted into a docking hole on the end face of the docking post; vertical holes with a blind hole design are provided on the upper surface of the upper housing, corresponding to each docking post, with the lower end of the vertical hole extending to the lower end of the docking post; screw holes are provided inside the bottom surface of the vertical holes for arranging connecting screws, with the lower end of the connecting screw passing through the screw hole and threaded into the threaded hole of the connecting post.

[0007] In this way, during the assembly of the upper and lower housings in the aforementioned power bank casing structure, the connecting posts are inserted into the corresponding mating holes on the end faces of the mating posts. This prevents misalignment between the open ends of the upper and lower housings. Connecting screws are then placed in the vertical holes, with the lower ends of the screws passing through the screw holes and threaded into the threaded holes on the connecting posts. This securely assembles and fixes the upper and lower housings together, improving their stability. Furthermore, the mating of the connecting posts and mating posts enhances the overall structural strength of the casing, providing better protection for the internal electrical components.

[0008] Furthermore, the connecting columns are three arranged at intervals along the longitudinal direction of the shell.

[0009] As an optimization, the connecting column and the lower shell are integrally formed; the docking column and the upper shell are integrally formed.

[0010] This makes the structural design of the upper and lower shells more reasonable and easier to process and manufacture.

[0011] As an optimization, the mating hole includes a lower section of the mating hole at the bottom and an upper section of the mating hole at the top. The lower section of the mating hole is designed as a circular hole, while the upper section of the mating hole is designed as a tapered hole with a smaller diameter at the top and a larger diameter at the bottom. Furthermore, a chamfered structure is provided at the upper end of the connecting post.

[0012] In this way, the structural design of the mating hole and the connecting post is more reasonable, making it easier to insert the corresponding connecting post into the mating hole during assembly.

[0013] As an optimization, a plug made of rubber is provided at the upper end of the vertical hole.

[0014] By installing a plug, dust can be better prevented from entering, thus keeping the area cleaner.

[0015] Furthermore, the vertical hole includes an upper section of the vertical hole at the top and a lower section of the vertical hole at the bottom, and the diameter of the lower section of the vertical hole is set to be smaller than the diameter of the upper section of the vertical hole, and the plug is installed in the upper section of the vertical hole, with the lower end of the plug abutting against the stepped surface formed by the lower section of the vertical hole and the upper section of the vertical hole.

[0016] This allows the plug to be positioned to a certain extent, preventing it from falling to the bottom of the vertical hole.

[0017] As an optimization, the electrical component structure includes a battery installed in the upper housing; a first mounting plate and a second mounting plate are respectively provided at the front and rear ends of the lower surface of the battery, and mounting posts are respectively provided in the upper housing corresponding to the ends of the first mounting plate and the second mounting plate, and fixing holes are respectively provided at the ends of the first mounting plate and the second mounting plate for arranging fixing screws, so that the fixing screws can be threadedly connected to the mounting posts; the outer sides of the first mounting plate and the second mounting plate protrude outward to form a first limiting plate and a second limiting plate, and the distal ends of the first limiting plate and the second limiting plate are respectively bent upward to form a first limiting strip and a second limiting strip, and the inner sides of the first limiting strip and the inner sides of the second limiting strip are respectively attached to the front and rear end faces of the battery to restrict the longitudinal position of the battery in the housing.

[0018] In this way, by setting up a first mounting plate and a second mounting plate, and by forming a first limiting plate and a second limiting plate on the first mounting plate and the second mounting plate respectively, the battery can be better constrained and fixed, thereby better protecting the battery.

[0019] As an optimization, a ring-shaped mounting flange is provided on the inner circumferential surface of the front end of the housing, and a ring-shaped mounting groove is provided on the surface of the mounting flange; the electrical component structure includes a circuit board disposed inside the front end of the housing, such that the edge of the circuit board is mounted in the mounting groove; the charging and discharging interface is provided on the circuit board; and the clearance opening is provided on the front end surface of the housing.

[0020] In this way, by setting an mounting flange and a mounting groove on the mounting flange for mounting the circuit board, the circuit board is installed more stably and reliably, thereby better avoiding the movement of the circuit board position after repeated plugging and unplugging, and avoiding the displacement of the charging interface position.

[0021] As an optimization, the charging and discharging interface includes a USB interface, a Type-C interface, and a DC interface; there are two Type-C interfaces and two DC interfaces; a switch button is also provided on the circuit board, and a button mating hole is provided at the front of the housing corresponding to the switch button so that the outer end of the switch button can protrude to the outside.

[0022] This makes the charging and discharging interface design more reasonable.

[0023] As an optimization, the central area of ​​the front end of the housing is recessed inward to form a rectangular mating notch. The clearance opening and button mating hole are provided on the bottom surface of the mating notch and extending through the wall thickness direction. A protective cover with a rectangular plate structure is provided inside the mating notch, and an insertion post is integrally formed at a corner position on the inner surface of the protective cover. An insertion mating hole is provided on the bottom surface of the mating notch corresponding to the insertion post, so that the insertion post can be inserted into the insertion mating hole.

[0024] In this way, by setting a mating notch at the front end of the housing and placing a protective cover inside the mating notch, dust can be better prevented from entering the charging and discharging interface, thus providing protection.

[0025] As an optimization, the plug-in post includes a front section, a middle section, and a rear section, and the diameter of the middle section is set to be larger than the diameters of the front and rear sections; and after the plug-in post is inserted into the mating hole, the inner side of the middle section can be supported against the inner circumferential surface of the housing to prevent the plug-in post from coming out.

[0026] This design allows the protective cover to rotate around the insertion hole after it is removed, and because the insertion pin on the protective cover is always engaged in the insertion hole, the protective cover will not fall off, making it more convenient to use.

[0027] Furthermore, a chamfered structure is provided at the outer end of the middle section of the plug-in post.

[0028] Furthermore, the protective cover is made of silicone material.

[0029] Furthermore, a display circuit board is provided inside the lower housing, and a mounting opening is provided on the lower housing corresponding to the display circuit board, and a display cover plate made of transparent material is installed accordingly.

[0030] In summary, the above structure has the advantages of simpler and more reasonable structural design, easier assembly, better installation and fixation of internal components, and better prevention of dust from entering the shell. Attached Figure Description

The plug is installed in the upper section of the vertical hole, and the lower end of the plug is attached to the stepped surface formed by the lower and upper sections of the vertical hole.
