Description

Technical Field

[0001] This utility model relates to the field of charger technology, and in particular to a fixed and drop-proof electric vehicle charger structure. Background Technology

[0002] As a core device for replenishing the energy of electric vehicles, the electric vehicle charger is a specialized power conversion device that transforms mains power into electricity suitable for the charging needs of electric vehicle batteries. It integrates cutting-edge advancements in modern power electronics technology, relying on advanced switching power supply conversion technology to achieve efficient rectification, filtering, and voltage transformation of the input mains power. At the intelligent control level, the charger's built-in microcontroller, equipped with sophisticated algorithms, can monitor key parameters such as battery voltage, current, and temperature in real time throughout the charging cycle. Based on this dynamic data, the charger intelligently adjusts its charging strategy according to the chemical characteristics and performance curves of different battery types. This ensures that the constant current phase rapidly replenishes the battery, while the constant voltage phase precisely controls the voltage to ensure the battery reaches full charge within a safe voltage threshold. This refined control mechanism not only effectively avoids the risks of battery bulging, overheating, and even fire caused by overcharging, but also eliminates battery capacity loss caused by undercharging, fundamentally guaranteeing battery lifespan and safety.

[0003] In actual electric vehicle charging operations, the reliability of the charger's mounting device directly affects the continuity and safety of the charging process. Due to the lack of dedicated mounting devices for some chargers, or the insufficient strength and poor adaptability of existing mounting structures, chargers are prone to accidentally slipping off the electric vehicle's charging port during charging due to vehicle vibration, external force, or other factors. Once the charger detaches, the charging plug connected to the mains socket will be forcibly pulled out due to the dragging of the cable, causing a momentary interruption of the originally closed charging circuit. This unexpected power outage not only prevents the battery from completing a full charging cycle, affecting the driving range, but may also cause irreversible electrical damage to the charger's internal circuitry and battery electrodes due to instantaneous current fluctuations, creating serious safety hazards such as short circuits and leakage, posing a potential threat to the life and property safety of users. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that the charger slips off the electric vehicle due to unstable fixing, causing the charging plug to fall off the socket and resulting in unexpected interruption of the charging process. Therefore, a fixed and drop-proof electric vehicle charger structure is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a fixed and anti-fall electric vehicle charger structure, comprising a charger body, a positioning frame movably snapped onto one side of the charger body, a positioning side plate fixedly connected to one end of the other side of the positioning frame, a positioning hole No. 1 opened inside the positioning side plate, a positioning hook provided on one side of the charger body, the positioning hook being fixedly attached to one side of the electric vehicle foot pedal, and one end of the positioning hook being located inside the positioning hole No. 1.

[0006] Preferably, the positioning frame includes a long plate and two positioning side frames, the long plate is fixedly connected between the two positioning side frames, and the two ends of the positioning side frames are respectively provided with positioning holes.

[0007] Preferably, the charger body has symmetrical grooves on both sides, an adjustment plate is fixedly connected inside the groove, and a positioning block is fixedly connected to one end of the adjustment plate.

[0010] Preferably, the cable positioner includes a connecting base, a winding rod, and a baffle plate, wherein the winding rod is fixedly connected to one end of the connecting base, and the baffle plate is fixedly connected to the other end of the winding rod.

[0011] Preferably, a positioning rod is symmetrically fixedly connected to one side of the charger body, and one end of the positioning rod is threaded into the inside of the connecting base.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, the charger body and the positioning frame are placed together on the corresponding side of the positioning hook. Through precise assembly, one end of the positioning hook can movably pass through the No. 1 positioning hole, constructing a stable mechanical support structure.

[0022] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0024] Example 1: As Figures 1-3As shown, this utility model provides a fixed and anti-fall electric vehicle charger structure, including a charger body 1. A positioning frame 2 is movably snapped onto one side of the charger body 1, and a positioning side plate 5 is fixedly connected to one end of the other side of the positioning frame 2. A positioning hole 51 is opened inside the positioning side plate 5. A positioning hook 3 is provided on one side of the charger body 1. The positioning hook 3 is fixedly glued to one side of the electric vehicle foot pedal. One end of the positioning hook 3 is located inside the first positioning hole 51. The positioning frame 2 includes a long plate 21 and two positioning side plates 22. 21 is fixedly connected between two positioning side frames 22. The two ends of the positioning side frames 22 are respectively provided with second positioning holes 221. The two sides of the charger body 1 are symmetrically provided with grooves 11. An adjustment plate 111 is fixedly connected inside the groove 11. A positioning block 112 is fixedly connected to one end of the adjustment plate 111. When the adjustment plate 111 is not pressed, the positioning block 112 is locked inside the second positioning hole 221. The other side of the positioning hook 3 is fixedly connected to the mounting side plate 31. The mounting side plate 31 is fixedly glued to one side of the electric vehicle foot pedal.

[0025] The specific setup and function of this embodiment are described below. After the plug and socket of the charger body 1 are reliably connected, the charger body 1 and the positioning frame 2 are placed together on the corresponding side of the positioning hook 3. Through precise assembly, one end of the positioning hook 3 can be movably inserted through the first positioning hole 51, constructing a stable mechanical support structure. This design, through the principle of three-point force balance, effectively avoids the risk of the charger body 1 falling due to the shift of the center of gravity during charging, significantly improving the stability and safety of the charging operation. When it is necessary to disassemble the positioning frame 2, pressing the adjustment plate 111 triggers its mechanical linkage mechanism, causing the positioning block 112 to move downward in the vertical direction, thereby releasing the locking constraint with the second positioning hole 221.

[0026] Example 2: Figures 1-5 As shown, the fixed anti-fall electric vehicle charger structure of this utility model includes a charger body 1. A positioning frame 2 is movably snapped onto one side of the charger body 1. A positioning side plate 5 is fixedly connected to one end of the other side of the positioning frame 2. A positioning hole 51 is opened inside the positioning side plate 5. A positioning hook 3 is provided on one side of the charger body 1. The positioning hook 3 is fixedly glued to one side of the electric vehicle foot pedal. One end of the positioning hook 3 is set inside the first positioning hole 51. A cable locator 4 is symmetrically arranged on one side of the charger body 1. The cable locator 4 includes a connecting base 41, a winding rod 42 and a baffle 43. The winding rod 42 is fixedly connected to one end of the connecting base 41, and the baffle 43 is fixedly connected to the other end of the winding rod 42. A positioning rod 12 is symmetrically fixedly connected to one side of the charger body 1. One end of the positioning rod 12 is threaded into the inside of the connecting base 41. When the positioning rod 12 is not connected to the connecting base 41, a protective sleeve 121 is movably sleeved on its outside.

[0027] The overall effect of this embodiment is that when the wire between the charger body 1 and the charging plug is too long, the connecting base 41 in the cable locator 4 and the positioning rod 12 can be threaded together. Then, the redundant wire is tightly wrapped around the outside of the winding rod 42. At the same time, the baffle 43 provides a corresponding limiting block on one side of the cable, forming a physical barrier to effectively prevent it from slipping, thereby completing the efficient storage of the excessively long wire. When it is not necessary to store the wire, the cable locator 4 can be easily disassembled according to the designed disassembly process, and a corresponding protective sleeve 121 can be fitted on the outside of the positioning rod 12 to properly protect the positioning rod 12.

[0028] The usage and working principle of this device are as follows: After reliably connecting the plug and socket of the charger body 1, place the charger body 1 together with the positioning frame 2 on the corresponding side of the positioning hook 3. Through precise assembly, one end of the positioning hook 3 can movably pass through the first positioning hole 51, constructing a stable mechanical support structure. When it is necessary to disassemble the positioning frame 2, press the adjusting plate 111 to trigger its mechanical linkage mechanism, causing the positioning block 112 to move downward in the vertical direction, thereby releasing the locking constraint with the second positioning hole 221.

[0029] When the wire between the charger body 1 and the charging plug is too long, the connecting base 41 in the cable locator 4 can be threadedly connected to the positioning rod 12. Then, the redundant wire is tightly wound around the outside of the winding rod 42. At the same time, the baffle 43 provides a corresponding limiting block on one side of the cable, forming a physical barrier to effectively prevent it from slipping.

[0030] When there is no need to store the wires, the cable locator 4 can be easily disassembled according to the designed disassembly procedure, and a corresponding protective sleeve 121 can be fitted on the outside of the positioning rod 12 to properly protect the positioning rod 12.

[0031] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
