Description

Technical Field

[0001] This utility model relates to the field of transformer technology for mobile phone chargers, specifically to a drop-proof electronic transformer assembly. Background Technology

[0002] A mobile phone charger, also known as a power bank or portable charger, is essentially a device that converts alternating current (AC) to direct current (DC) to power portable electronic devices such as mobile phones. It consists of a stable power supply (primarily a voltage regulator) providing a stable operating voltage and sufficient current, along with necessary control circuits such as constant current, voltage limiting, and time limiting circuits. Its core function is to convert household AC power into DC power suitable for mobile phones. The main structure of a mobile phone charger includes a high-voltage section, a transformer, and a low-voltage power supply section. The high-voltage section is typically connected to 220V AC power, the transformer converts the high-voltage AC power to low-voltage DC power, and the low-voltage power supply section is connected to the mobile phone, with an output voltage typically below 5V.

[0003] Chinese patent document (publication application number CN212676047U) discloses a transformer structure for a mobile phone charger, including a housing. Two power connectors are fixedly installed on the top of the housing, and a USB port is provided on the bottom of the housing. A USB data cable is plugged into the USB port and electrically connected to the USB port. Multiple heat dissipation vents are provided on the upper and lower outer walls of the housing. Two mounting plates are slidably connected inside the housing. A baffle is fixedly installed on the top of one mounting plate and the bottom of the other mounting plate. A first shock-absorbing spring is fixedly installed on one side of the baffle, and the other end of the first shock-absorbing spring is fixedly connected to the inner wall of the housing. Heat dissipation plates are slidably connected to both mounting plates.

[0004] The transformer structure inside the charger is electrically connected to the connector and the USB port, and works with the spring structure at both ends to provide cushioning protection during drops or impacts. However, the transformer structure relies solely on springs for cushioning and lacks damping properties. When subjected to severe impacts, it is prone to frequent vibrations due to the elasticity of the springs, affecting the stability of the transformer connection and limiting its protective effect. Therefore, we propose a drop-proof electronic transformer assembly. Utility Model Content

[0005] The summary section of this application is intended to provide a brief overview of the concepts, which will be described in detail in the detailed description section below. This summary section is not intended to identify key or essential features of the claimed technical solutions, nor is it intended to limit the scope of the claimed technical solutions.

[0006] The purpose of this invention is to provide a drop-proof electronic transformer assembly to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an electronic transformer assembly that can prevent falls, including an outer shell frame, an inner skeleton inside the outer shell frame, and buffer frames distributed at both ends of the top surface of the inner skeleton frame. The buffer frames include side plate frames, and a positioning plate is connected to one side of the side plate frames. Outer springs are distributed at both ends of the other side of the side plate frames, and a buffer post is provided at the center of the outer spring. A rubber head is connected to one end of the buffer post, and a telescopic rod is connected to the other end of the buffer post. A limit block is connected to one end of the telescopic rod, and an inner spring is attached to one end of the limit block.

[0008] Furthermore, the buffer pile and the rubber head are fixedly connected, and the buffer pile is elastically extended and retracted with the telescopic rod through an inner spring.

[0009] Furthermore, the buffer piles and outer springs are symmetrically distributed along both sides of the side plate frame, and the side plate frame is fixedly connected to the positioning plate.

[0010] Furthermore, the outer frame includes an outer frame, and an inner skeleton is engaged with the inner wall of the outer frame. Rubber gaskets are embedded in the two outer walls of the outer frame, and a buckle plate is engaged with one end of the outer frame.

[0011] Furthermore, one end of the outer frame is fastened to the four perimeter of the buckle plate, and rubber pads are symmetrically embedded and fixed along the outer walls of both sides of the outer frame.

[0012] Furthermore, the inner frame includes a base frame, the notches at both ends of the base frame engaging with the inner walls of the outer frame, and a circuit board connected to the top surface of the base frame via screw posts. The top surface of the circuit board is connected to the transformer body, and one end of the circuit board is connected to a plug, while the other end of the circuit board is connected to a USB port.

[0013] Furthermore, the plug and USB port are electrically connected to the circuit board, and the transformer body is fixed to the top surface of the circuit board by welding.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] When the transformer assembly is subjected to a drop or impact, the impact force on the casing is buffered by the outer spring. When the buffering reaches a certain level, the contact buffer pile provides damping through the buffer pile and rubber head, and is further buffered by the elastic extension and retraction of the internal telescopic rod, forming a double buffering and damping process. In addition, each set of side plate frames can be in contact with the transformer body through the positioning plate, providing internal structural support and protective stability.

[0016] The outer shell of this component forms external protection through rubber pads embedded in the outer walls on both sides. When the component structure is dropped or bumped, the external rubber pads can provide cushioning for the outer walls on both sides of the main body, and the opening at one end of the outer frame is fastened with the buckle to form a closed space, providing external protection for the internal frame and keeping the internal transformer stable.

[0017] The interior of this transformer assembly provides mounting space for the circuit board and the transformer body through a base frame. At the same time, the base frame itself is fixed to the circuit board with screw posts. The base frame can be fixed to the side plate frames at both ends to form a whole, forming a semi-enclosed space, thereby providing further internal structural protection for the transformer body.

[0027] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0028] This utility model provides, for example Figure 1-4 The electronic transformer assembly shown includes an outer frame 1, an inner skeleton 2 is provided inside the outer frame 1, and buffer frames 3 are distributed at both ends of the top surface of the inner skeleton 2. The outer frame 1 includes an outer frame 101, and the inner skeleton 2 is engaged with the inner wall of the outer frame 101. Rubber pads 102 are embedded in the outer walls on both sides of the outer frame 101, and a buckle plate 103 is engaged with one end of the outer frame 101.

[0029] To maintain the protective properties of the external housing structure of this transformer assembly, such as Figure 1 As shown, the outer shell of this component forms external protection through rubber pads 102 embedded in the outer walls on both sides. When the component structure is dropped or bumped, the rubber pads 102 on the outside can provide cushioning for the outer walls on both sides of the main body. The opening at one end of the outer frame 101 is fastened with the buckle plate 103 to form a closed space, providing external protection for the inner frame 2 installed inside and maintaining the stable operation of the internal transformer.

[0030] like Figure 2 As shown, the inner frame 2 includes a base frame 201. The notches at both ends of the base frame 201 engage with the inner walls of the outer frame 101. A circuit board 202 is connected to the top surface of the base frame 201 via screw posts. A transformer body 203 is connected to the top surface of the circuit board 202. A plug 204 is connected to one end of the circuit board 202, and a USB port 205 is connected to the other end of the circuit board 202.

[0031] To provide protection and stability for the internal structure, such as Figure 2 As shown, the housing of this transformer assembly provides mounting space for the circuit board 202 and the transformer body 203 through the base frame 201. At the same time, the base frame 201 itself is fixed to the circuit board 202 with screw posts. The base frame 201 can be fixed to the side plate frames 301 at both ends to form a whole, forming a semi-enclosed space, thereby providing further internal structural protection for the transformer body 203.

[0032] like Figure 3-4As shown, the buffer frame 3 includes a side plate frame 301, and a positioning plate 302 is connected to one side of the side plate frame 301. Outer springs 303 are distributed at both ends of the other side of the side plate frame 301, and a buffer post 304 is provided at the center of the outer spring 303. A rubber head 305 is connected to one end of the buffer post 304, and a telescopic rod 306 is connected to the other end of the buffer post 304. A limit block 307 is connected to one end of the telescopic rod 306, and an inner spring 308 is attached to one end of the limit block 307.

[0033] Finally, to provide cushioning in the event of bumps and falls, such as Figure 3-4 As shown, when this transformer assembly is subjected to a drop or impact, the impact force on the casing when it falls will be buffered by the outer spring 303. When the buffering reaches a certain level, the contact buffer pile 304 will provide damping through the buffer pile 304 and the rubber head 305. The internal telescopic rod 306 will elastically extend and retract to provide further buffering, forming a double buffering and damping process. In addition, each set of side plate frames 301 can be in contact with the transformer body 203 through the positioning plate 302 to provide internal structural support and protective stability.

[0034] In summary, when this power supply device is in use, the impact force of the transformer assembly being bumped first affects the outer frame 101. The rubber pads 102 on both sides provide cushioning on the outer wall. The continuous force continues to enter the interior through the shell. The impact force on the shell when it falls is cushioned by the outer spring 303. When the outer spring 303 is subjected to force, it is compressed. At this time, as the force is applied, the rubber head 305 of the buffer pile 304 contacts the inner wall of the shell, providing damping after cushioning. If the force still exists, the telescopic rod 306 of the buffer pile 304 will elastically cushion again with the inner spring 308, forming an internal and external elastic cushioning process.

[0035] The above description is merely a selection of preferred embodiments of this disclosure and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the invention involved in the embodiments of this disclosure is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the above-described inventive concept.
