Description

Technical Field

[0001] This utility model relates to the field of injection molding shell technology, specifically to an injection molding shell for power banks. Background Technology

[0002] In the current field of power bank casing design, traditional injection-molded casing structures present numerous inconveniences in component installation. Typically, during power bank casing assembly, the internal components are fixed and immovable. This necessitates precise manipulation within a confined space when installing components. Due to the casing's structural limitations, the installer's hand movement is restricted, making the installation process difficult and time-consuming. This not only increases production costs but also increases the risk of component damage or improper installation, affecting the overall quality and performance of the power bank.

[0003] Meanwhile, the internal structural stability of traditional power banks often relies on a single connection method, lacking multiple fixing and support mechanisms. During the use of power banks, internal components may loosen or shift due to factors such as vibration and impact, which may affect the normal operation of the power bank or even cause safety hazards.

[0004] Furthermore, in terms of the protection of power bank casings, existing casing designs do not adequately consider the installation of external protective layers. Most casings lack a structure specifically designed for easy installation of protective layers, making it difficult to ensure the flatness and stability of the installation when installing external protective layers such as foam layers. This can easily lead to problems such as protective layers falling off or shifting, failing to effectively perform the protective function of the protective layer and reducing the lifespan and reliability of the power bank. Utility Model Content

[0005] In order to overcome the shortcomings of existing technical solutions, this utility model provides an injection-molded shell for power banks, which can effectively solve the technical problems of the current injection-molded shells for power banks being inconvenient for the installation of internal components and having an unstable structure.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] An injection-molded casing for a power bank includes a hollow casing and two side sealing panels. The casing has openings at both ends, and the side sealing panels are respectively installed at the two open ends of the casing. An installation plate for mounting power bank components is suspended inside the casing. The installation plate has extensions at both ends, which contact the inner wall of the casing and are fixed by pre-set slots in the casing. The slots are connected to the two open ends of the casing, allowing the installation plate to move into the interior of the casing along the direction of the slots.

[0008] The housing has limiting mounting grooves at both ends that match the shape of the side sealing panel. The side sealing panel is provided with several insert rods. The side sealing panel and the housing are fixed by inserting the insert rods into the bottom of the limiting mounting grooves, and a locking member is inserted into the side sealing panel to lock it to the housing through the insert rods.

[0009] The outer side of the housing has an annular groove that connects the two ends. The annular groove is used to install a sponge layer that protects the outer surface of the housing, and the two ends of the sponge layer extend to the two ends of the housing.

[0010] Furthermore, the mounting plate is provided with a circuit board mounting station and a battery mounting station, and the bottom of both the circuit board mounting station and the battery mounting station is provided with heat dissipation holes that penetrate the bottom of the mounting plate.

[0011] Furthermore, the side panel near the circuit board mounting station is provided with a charging hole and a switch control hole.

[0012] Furthermore, the inner wall of the housing is also provided with a support strip that supports the bottom of the mounting plate, and the bottom of the mounting plate is provided with a foolproof groove that engages and fixes with the support strip.

[0013] Furthermore, the inner wall of the housing is symmetrically provided with protrusions, and the insertion rod is inserted into a pre-set slot in the protrusion for fixation.

[0014] Furthermore, the annular groove is provided with anti-slip parts that are connected end to end.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] The injection-molded shell for power banks provided by this utility model adds a mounting plate that can be pushed in and fixed inside the shell. This allows the mounting plate to be pushed into the shell along the direction of the slot after the power bank components are installed, which greatly facilitates the installation of the components and avoids the inconvenience caused by the structural limitations of the shell. The stability of the internal structure is improved by combining with the side sealing plate. In addition, an annular groove is provided on the outer side of the shell to facilitate the installation of the sponge layer, which can not only facilitate the installation of the sponge layer that protects the outer surface of the shell, but also improve the stability of the sponge layer after installation.

[0026] 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.

[0027] like Figure 1-4 As shown, this technical solution provides an injection-molded shell for a power bank, whose structure mainly consists of a shell 1 and two side sealing panels 2. The shell 1 has a hollow structure with openings at both ends, and the side sealing panels 2 are respectively installed at the two open ends of the shell 1. In addition, a mounting plate 3 is suspended inside the shell 1 for installing power bank components. A locking member 4 is used to lock and fix the side sealing panels 2 to the shell 1, and a sponge layer 5 is installed in the annular groove 103 on the outside of the shell 1 to protect the outer surface of the shell 1.

[0028] The housing 1 has a pre-set slot 101 inside, which communicates with the two open ends of the housing 1. The mounting plate 3 has extensions 301 at both ends, which contact the inner wall of the housing 1 and insert into the slot 101, allowing the mounting plate 3 to move along the direction of the slot 101 into the interior of the housing 1. During installation, the mounting plate 3 is pushed in from the end communicating with the slot 101 until it is fully inserted into the appropriate position inside the housing 1. The inner wall of the housing 1 also has a support strip 105 supporting the bottom of the mounting plate 3. The bottom of the mounting plate 3 has a foolproof groove 305 that engages with the support strip 105. The engagement of the support strip 105 with the foolproof groove 305 further improves the stability of the mounting plate 3 within the housing 1.

[0029] The mounting plate 3 is movable and can be installed by engaging with the slot 101 of the housing 1 through the extension 301. At the same time, the anti-fooling groove 305 at the bottom of the mounting plate 3 engages with the support strip 105 on the inner wall of the housing 1 to ensure the accuracy and stability of the mounting plate 3 during installation and prevent the mounting plate 3 from shaking inside the housing 1.

[0030] The mounting plate 3 is provided with a circuit board mounting station 302 and a battery body mounting station 303 for mounting the power bank's circuit board and battery body, respectively. Both the circuit board mounting station 302 and the battery body mounting station 303 have heat dissipation holes 304 extending through the bottom of the mounting plate 3, which facilitates heat dissipation of the power bank's internal components and improves the power bank's lifespan and stability.

[0031] Both ends of the housing 1 are provided with limiting mounting grooves 102 whose shape matches that of the side sealing panel 2. The side sealing panel 2 is provided with several insert rods 201. During installation, the insert rods 201 of the side sealing panel 2 are aligned with the limiting mounting grooves 102 and inserted until the insert rods 201 are inserted to the bottom of the limiting mounting grooves 102. Then, locking elements 4, such as screws, are inserted into the side sealing panel to lock it to the housing 1 through the insert rods 201, thus firmly fixing the side sealing panel 2 to the housing 1. The inner wall of the housing 1 is symmetrically provided with protrusions 106. The insert rods 201 are inserted into the pre-set slots 107 of the protrusions 106 for fixation, thereby enhancing the connection strength between the side sealing panel 2 and the housing 1.

[0032] The side panel 2 near the circuit board mounting station 302 has a charging port 202 and a switch control port 203 for convenient charging and switch control of the power bank. The side panel 2 is initially fixed to the housing 1 by engaging with the limiting mounting groove 102 and the slot 107 of the protrusion 106 of the housing 1 through the insertion rod 201, and then finally locked by the locking member 4 to ensure a firm and reliable connection between the side panel 2 and the housing 1.

[0033] An annular groove 103 with continuous ends is provided on the outer side of the housing 1. When installing the sponge layer 5, it is fitted onto the outer side of the housing 1, so that both ends of the sponge layer 5 extend to both ends of the housing 1, ensuring that the sponge layer 5 fits tightly in the annular groove 103, providing good protection. An anti-slip part 104 with continuous ends is provided in the annular groove 103, which can increase the friction between the sponge layer 5 and the annular groove 103 and prevent the sponge layer 5 from sliding.

[0034] In use, the user can first install the corresponding components of the power bank on the mounting plate 3, and then push the mounting plate 3 into the housing 1 from the end with the slot 101. Before pushing it in, the extension 301 is inserted into the slot 101, and at the same time, the bottom of the mounting plate 3 is engaged and fixed with the support strip 105 on the inner wall of the housing 1 to ensure proper positioning before pushing in. After the mounting plate 3 is pushed in, the insertion rod 201 of the side sealing panel 2 is aligned with the limiting mounting groove 102 and the slot 107 of the protrusion 106 at both ends of the housing 1 and inserted, so that the side sealing panel 2 is initially fixed on the housing 1. The locking piece 4 is inserted into the side sealing plate to lock and fix the side sealing panel 2 to the housing 1. Finally, the sponge layer 5 can be put on the outside of the housing 1, so that the two ends of the sponge layer 5 extend to the two ends of the housing 1, ensuring that the sponge layer 5 fits tightly in the annular groove 103.

[0035] In summary, the injection-molded shell for power banks provided by this technical solution adds a mounting plate 3 inside the shell 1 that can be pushed in and fixed inside. This allows the mounting plate 3 to be pushed in and fixed inside the shell 1 along the direction of the slot 101 after the power bank components are installed, which greatly facilitates the installation of components and avoids the inconvenience caused by the structural limitations of the shell 1. Furthermore, the stability of the internal structure is improved by combining with the side sealing plate 2. In addition, an annular groove 103 is provided on the outer side of the shell 1 to facilitate the installation of the sponge layer 5, which can not only facilitate the installation of the sponge layer 5 that protects the outer surface of the shell 1, but also improve the stability of the sponge layer 5 after installation.
