Description

Technical Field

[0001] This utility model relates to a household stationary electric vehicle charger, belonging to the technical field of charger equipment. Background Technology

[0002] Currently, most household electric vehicle chargers are freestanding designs, typically placed on the ground or hung on temporary supports. Their unpredictable location makes them prone to safety hazards due to pulling, stepping, or damp environments. Furthermore, their power and charging cords are often scattered haphazardly, affecting aesthetics and posing a tripping hazard. In addition, most of these chargers lack effective heat dissipation design and a stable installation structure, which can lead to heat buildup affecting performance over time. They are also difficult to neatly and securely install on walls, pillars, or other suitable locations, causing inconvenience for users. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide a household fixed electric vehicle charger that can fix the charger, effectively manage the charging cable, and improve the safety and convenience of use.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is: a household stationary electric vehicle charger, comprising: The mounting bracket is movably mounted with two opposing clamping claws, and a clamping cavity is provided between the two clamping claws; A charger housing, wherein the charger housing is installed in the clamping cavity, and the charger housing has a mounting cavity; A charging circuit module, wherein the charging circuit module is installed in the mounting cavity; A power input terminal is provided at one end of the charger housing and is electrically connected to the charging circuit module. The power input terminal is adapted to be connected to an external power supply. A charging output terminal is disposed at the other end of the charger housing and electrically connected to the charging circuit module. The charging output terminal is adapted to be electrically connected to an electric vehicle.

[0005] Furthermore, to increase the flexibility of use, a home-use stationary electric vehicle charger also includes a pluggable cable assembly, which includes a power supply cable and a charging cable. One end of the power supply cable is plugged into the power input terminal, and the other end of the power supply cable is plugged into an external power supply. One end of the charging cable is plugged into the charging output terminal, and the other end of the charging cable is plugged into the electric vehicle.

[0006] Furthermore, to avoid cable tangling and improve service life, a household fixed electric vehicle charger also includes a cable management tray. The cable management tray has a receiving cavity, and the cable management tray has a first cable port and a second cable port, both of which are connected to the receiving cavity. An elastic winding roller is rotatably mounted in the accommodating cavity, and the segments of the charging cable are wound around the elastic winding roller. The power supply cable is adapted to extend from the first cable port, and the charging cable is adapted to extend from the second cable port.

[0007] Furthermore, the mounting bracket has hanging holes on its back.

[0008] Furthermore, in order to accommodate charger housings of different specifications, the clamping claw is mounted on the mounting bracket via a movable rod. An elastic spring is sleeved on the movable rod, with one end of the elastic spring connected to the mounting bracket and the other end of the elastic spring connected to the clamping claw.

[0009] Furthermore, the charger housing is made of flame-retardant material.

[0010] Furthermore, the mounting bracket is also provided with a heat dissipation grille on its back.

[0011] By adopting the above technical solution, this utility model has the following beneficial effects: In this utility model, the user selects a suitable and stable location such as a wall or column, and uses the hanging holes on the back of the mounting bracket to firmly install the mounting bracket in the preset position using screws, expansion screws, etc. The user aligns the charger housing with the clamping cavity between the two clamping claws. Since the clamping claws are connected by elastic springs, pressure can be applied to open them. After the housing is pushed into the clamping cavity to a suitable depth, the clamping claws automatically close under the restoring force of the elastic springs, tightly clamping the two sides of the housing, thus completing the fixed installation of the charger body. Insert one end of the power cord into the power input terminal of the charger housing, and lead the other end of the power cord out from the first cable port of the cable management panel. Insert the other end of the power cord into a household AC power socket on a nearby wall to power on the charger. Take the charging cable that is already connected to the charging output terminal, hold the charging cable connector by hand, and smoothly pull out the required length of charging cable from the second cable port. Insert the charging connector at the other end of the charging cable into the charging interface of the electric vehicle. At this time, the charging circuit module starts to work, and the heat generated is dissipated through the heat dissipation structure on the back of the housing and bracket. Once the electric vehicle battery is fully charged, the user manually unplugs the charging connector from the electric vehicle and releases the charging cable. Under the restoring torque stored in the elastic winding roller, the charging cable is automatically and orderly retracted into the receiving cavity of the cable management tray, leaving only a few connectors outside for easy retrieval next time.
