Description

Technical Field

[0001] This utility model relates to the field of charger technology, and in particular to a charger with a retractable support base. Background Technology

[0002] With the widespread use of smartphones and other portable electronic devices, the demand for charging is constantly increasing, and users often face the problem of inconvenient device placement during charging. Especially while charging, many people want to be able to place their phones or other electronic devices stably in one location so they can perform other tasks. However, traditional charger designs typically do not consider the need to provide stable support for devices, forcing users to find additional supports while charging, or simply place the devices haphazardly, posing a risk of tilting or falling.

[0003] In addition, conventional plugs and wall sockets are only fixed by friction between metal springs. When the charging cable is pulled by external forces (such as a pet tripping over the cable or the user walking on it) or the socket is old, it is very easy to cause poor contact or even complete detachment, which poses a safety hazard of charging interruption and electrical sparks. Utility Model Content

[0004] The main purpose of this invention is to provide a charger with a retractable support base, which aims to solve the problem of chargers easily becoming loose and to provide an integrated mobile phone support.

[0005] To achieve the above objectives, the present invention provides a charger with a retractable support base, comprising:

[0006] The housing contains a charging circuit module and a fixed plug end;

[0007] The support base includes a telescopic support arm hinged to the top of the housing and a lifting structure disposed at the head end of the telescopic support arm for placing and supporting electronic equipment; and

[0008] The wall contact module is rotatably connected to the end of the telescopic support arm and is used to adhere and fix it to the wall surface.

[0009] When the support base is unfolded, the wall contact module, the plug end, and the support base together form a triangular support structure.

[0010] In one possible implementation, the telescopic support arm includes:

[0011] The first arm section, which is hinged to the top of the housing; and

[0012] The second arm segment, at least a portion of which is nested within the first arm segment and is axially slidable.

[0013] In one possible implementation, the wall contact module includes:

[0014] A connector, which is rotatably connected to the end of the telescopic support arm; and

[0015] The adsorption part is fixed to one end face of the connector and is used to provide adsorption force.

[0016] In one possible implementation, the lifting structure includes:

[0017] A receiving groove is provided on the end surface of the telescopic support arm; and

[0018] A horizontal support plate is hinged within the receiving groove, and its surface is provided with anti-slip parts.

[0019] In one possible implementation, the top of the housing is provided with a folding storage slot, and the support base is flush with the top surface of the housing when folded and stored.

[0020] This utility model's technical solution, through the cooperation of the telescopic support arm and the end wall contact module, forms a rigid triangular support structure between the suction cup adsorption point and the plug contact point, thereby distributing the lateral force on the plug and solving the problem of loosening caused by external pulling in traditional chargers, while also enhancing overall anti-tipping stability. Furthermore, the integrated foldable support structure at the head of the support arm allows the phone to be stably supported on the support base, solving the problem of needing to hold the phone during charging or having an external stand occupying socket space. In addition, the coordinated design of the storage slot on the top of the casing and the folding mechanism of the support frame achieves a fully folded structure that is flush with the top surface of the casing, balancing portability and practicality.

[0026] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0028] To address the problems in the background technology, this utility model proposes a charger with a retractable support base 2, comprising:

[0029] The housing 1 has a charging circuit module 11 inside and a plug end 12 fixed thereon.

[0030] Support base 2 includes a telescopic support arm 21 hinged to the top of the housing 1 and a lifting structure 22 disposed at the head end of the telescopic support arm 21 for placing and supporting electronic equipment; and

[0031] The wall contact module 3 is rotatably connected to the end of the telescopic support arm 21 and is used to adsorb and fix it to the wall.

[0032] When the support base 2 is unfolded, the wall contact module 3, the plug end 12 and the support base 2 together form a triangular support structure.

[0033] Combined with reference Figures 1 to 2As shown, in this embodiment, the housing 1 serves as the basic carrier and is integrally molded from high-strength engineering plastic. An internal charging circuit module 11 is embedded within it. This module integrates an AC-DC conversion circuit, a voltage regulation unit, and an overload protection device. This module is electrically connected to an external power interface to provide charging functionality for connected electronic devices. The exterior of the housing 1 has a plug end 12, which can be plugged into a power socket to provide power to the charging circuit module 11. The support base 2 consists of a telescopic support arm 21 and a lifting structure 22. The telescopic support arm 21 is connected to a storage slot on the top of the housing 1 via a stainless steel hinge shaft. The hinge shaft contains damping silicone grease, allowing the support arm to hover at any angle within the range of 0-120 degrees. When the support base 2 is extended, the length of the telescopic support arm 21 can be adjusted, allowing the support base 2 to be adjusted to different heights and angles as needed to support electronic devices. The charger's support base 2 can be stored inside the housing 1 for easy carrying and storage. When not supporting electronic devices, the user can retract the support base 2 into the housing 1, reducing space occupation and making the charger more compact. The telescopic support arm 21 has a lifting structure 22 at its head (near the housing 1) for placing and supporting electronic equipment. It ensures that the equipment placed on it will not fall due to instability or tilting, and has a certain load-bearing capacity.

[0034] Furthermore, the wall contact module 3 is rotatably connected to the end of the telescopic support arm 21, enabling it to contact and adhere to the wall surface. The wall contact module 3 is typically fixed using adsorption or magnetic attraction; the adsorption structure design ensures that the support base 2 can be firmly adhered to the wall during use and is not easily detached. When the support base 2 is extended, the wall contact module 3, the plug end 12, and the support base 2 form a triangular support structure.

[0035] The implementation method of this application is as follows: First, insert the plug of the housing 1 into the wall socket, pull out the support arm to the required length and lock it. Then, press the wall contact module 3 onto the wall above the plug for suction fixation. Finally, unfold the lifting structure 22 and place the phone horizontally on top of it. At this time, a stable triangular support structure is formed with the plug contact point and suction cup adsorption point as the bottom vertex and the support arm as the hypotenuse. This allows the lifting structure 22 to support the weight of the phone. When storing, reverse the operation of each mechanism. After the support arm is folded, it is completely embedded into the storage groove of the housing 1, and the outer surface of the suction cup is flush with the top surface of the housing 1.

[0036] In one possible implementation, the telescopic support arm 21 includes:

[0037] The first arm segment 211 is hinged to the top of the housing 1; and

[0038] The second arm segment 212 is at least partially nested within the first arm segment 211 and is axially slidable.

[0039] Combined with reference Figure 2 As shown, in this embodiment, the telescopic support arm 21 adopts a double-layer nested sliding structure. The first arm section 211 is connected to the damping pivot on the top of the housing 1 via a stainless steel hinge shaft. This arm section is a hollow aluminum alloy profile with a rectangular cross-section, and axial slide rail grooves are precisely machined on both sides of the inner cavity. The proximal end of the second arm section 212 is inserted into the inner cavity of the first arm section 211. The two sides of this end are provided with protruding T-shaped sliders that match the slide rail grooves, allowing the second arm section 212 to slide 60mm axially along the first arm section 211. When the distal end of the second arm section 212 extends 80% of the total length of the support arm, its root limiting boss engages with the end of the first arm section 211 to achieve anti-disengagement locking.

[0040] In one possible implementation, the wall contact module 3 includes:

[0041] Connector 31, which is rotatably connected to the end of the telescopic support arm 21; and

[0042] The adsorption part 32 is fixed to one end face of the connector 31 and is used to provide adsorption force.

[0043] Combined with reference Figure 1 and Figure 2 As shown, in this embodiment, the wall contact module 3 includes a connector 31 and an adsorption part 32. One end of the connector 31 is rotatably connected to the end of the telescopic support arm 21, allowing the wall contact module 3 to rotate during use to adapt to different wall angles. The connector 31 is designed to ensure a stable connection with the telescopic support arm 21 and provide sufficient rotational flexibility. The adsorption part 32 is fixed to the side end face of the connector 31 and is used to firmly adsorb the wall contact module 3 onto the wall surface through adsorption force. The adsorption part 32 uses a material with strong adsorption force (such as a suction cup or magnetic material) to achieve effective fixation. The adsorption part 32 can also adopt a vacuum locking suction cup structure, specifically including: a suction cup body set on the end face of the connector 31, with an annular sealing flange on its edge; and a vacuum locking mechanism integrated into the central shaft of the suction cup. The working principle of this mechanism is: when the top knob is rotated clockwise, the internal precision screw drives the piston to move down to expel air, forming a negative pressure adsorption; rotating the knob counterclockwise releases the negative pressure.

[0044] In one possible implementation, the lifting structure 22 includes:

[0045] A receiving groove 221 is disposed on the end surface of the telescopic support arm 21; and

[0046] A horizontal support plate 222 is hinged within the receiving groove 221, and its surface is provided with an anti-slip part 223.

[0047] Combined with reference Figure 1 and Figure 2As shown, in this embodiment, the receiving groove 221 is precision milled onto the upper surface of the telescopic support arm 21, and hinge shaft holes are provided on both sides of the bottom of the groove. The horizontal support plate 222 is stamped from stainless steel plate, with two symmetrical hinged lugs extending from its proximal end. These lugs are hinged to the receiving groove 221 via a micro-damping pivot, enabling 0-90 degree rotation and unfolding. The surface of the support plate is etched with anti-slip textures and is fitted with a silicone pad to form a composite anti-slip part 223. In the retracted state, the support plate is completely embedded in the receiving groove 221 and flush with the surface of the support arm.

[0048] In one possible implementation, the top of the housing 1 is provided with a folding storage slot 13, and the support base 2 is flush with the top surface of the housing 1 when folded. Specifically, a rectangular folding storage slot 13 is provided on the top of the housing 1, and limiting protrusions are provided at the four corners. The hinge shaft of the support frame is fixed to the bottom of the storage slot. When the support frame is folded, its telescopic arm is engaged between the limiting protrusions in the slot, and the wall contact module 3 and the lifting structure 22 are respectively engaged in the pre-made recesses at the end of the slot of the support base 2, so that the outer surface of the support frame and the top surface of the housing 1 are kept coplanar. A magnetic suction component can be provided at the bottom of the slot to achieve adsorption and fixation by cooperating with the iron-nickel alloy sheet inside the support frame.
