Description

Technical Field

[0001] This utility model relates to the field of protective cover technology, and in particular to a protective cover for a new energy vehicle charger. Background Technology

[0002] The protective cover of the new energy vehicle charger is an important part of the charging system. It is mainly used to protect the internal components of the charger (such as circuit boards, wiring harnesses, connectors, etc.) from damage caused by the external environment (rain, dust, collisions, etc.).

[0003] A search revealed a utility model patent with authorization announcement number CN211280665U, which discloses a cover plate for the electrical assembly of a new energy vehicle charger, relating to the field of new energy vehicle technology. By setting a large convex bump, the internal space of the charger can be increased, and more importantly, the structural strength of the cover plate can be increased. Since the cross-section of the large convex bump is set as a parallelogram with two inclined sides, when a hard object comes into contact with the cover plate, it will generally come into contact with the side of the large convex bump.

[0004] However, existing charger protective covers, once installed on the charger housing, form a closed loop, which can easily lead to heat buildup, affecting charging efficiency and even causing overheating malfunctions. Furthermore, the protective covers are generally installed using multiple bolts, which is not only time-consuming to maintain but also hinders rapid repairs. Therefore, improvements are needed. Utility Model Content

[0005] This utility model provides a protective cover for a new energy vehicle charger, which solves the problem of heat dissipation after installation of existing charger protective covers, and also solves the problem of inconvenient disassembly and assembly of existing charger protective covers.

Multiple silicone fins are fixedly connected to the top of the heat-conducting seat, and the multiple silicone fins are arranged in a straight line along the length direction of the heat-conducting seat. Each silicone fin has a groove opening inside, and the groove opening is set through the silicone fin. A baffle is fixedly connected to the top of the multiple silicone fins. A rubber block is fixedly connected to the four corners of the bottom of the baffle. A quick-release mechanism is provided on the side of the protective cover and the charger housing.

[0007] Preferably, each of the four bottom corners of the protective cover is fixedly connected with a positioning pin, which engages with the charger housing. The positioning pins serve to position the protective cover on the charger housing.

[0008] Preferably, the quick-release mechanism includes a mounting block fixedly connected to the side of the protective cover and a mounting shell fixedly connected to the side of the charger housing. The bottom of the mounting block contacts the top of the mounting shell. A insert is fixedly connected to the bottom of the mounting block and plugs into the mounting shell. A beveled block is slidably connected inside the mounting shell. A locking pin is fixedly connected to the beveled block and plugs into the insert. An arc-shaped pin is slidably connected to the bottom of the mounting shell, and the arc-shaped pin penetrates the mounting shell. The upper end of the arc-shaped pin abuts against the beveled surface of the beveled block, and a pressing block is fixedly connected to the other end of the arc-shaped pin. The quick-release mechanism facilitates the rapid installation and removal of the protective cover from the charger housing.

[0009] Preferably, a guide pin is fixedly connected to the inner wall of the mounting housing, the guide pin is slidably connected to the inclined block, and a spring is provided inside the inclined block. One end of the spring is fixedly connected to the guide pin, and the other end of the spring is fixedly connected to the inner surface of the inclined block. The guide pin and spring provide auxiliary repositioning for the inclined block.

[0010] Preferably, a corrugated sleeve is fixedly connected to the pressing block, and the corrugated sleeve is fixedly connected to the bottom of the mounting shell. The corrugated sleeve prevents the arc-shaped pin from falling off without affecting its sliding.

[0011] Preferably, a rotating rod is rotatably connected to the bottom of the mounting housing, and the rotating rod penetrates the mounting housing. A stop block is fixedly connected to the lower end of the rotating rod, and the stop block contacts the bottom of the pressing block. The stop block can be rotated by the rotating rod, and when it is located at the pressing block, it serves to prevent accidental activation of the pressing block.

[0012] Preferably, two limiting rings are fixedly connected to the rotating rod. Each limiting ring contacts the inner and outer surfaces of the mounting housing, respectively. Each limiting ring is fixedly connected with a rubber ball, which engages with the inner and outer surfaces of the mounting housing. The limiting rings and rubber balls provide a positioning function for the rotating rod and stop after rotation.

[0013] Compared with related technologies, the protective cover for a new energy vehicle charger provided by this utility model has the following beneficial effects: This utility model provides a protective cover for a new energy vehicle charger. By setting a slot in the middle of the original protective cover, a heat-conducting seat is set in the slot, and multiple silicone fins with waist-shaped openings are set on the heat-conducting seat. The silicone fins support a baffle with rubber blocks at the corners. In this way, the heat-conducting seat penetrates the cover and directly contacts the heat source, the silicone fins increase the heat dissipation area, and the waist-shaped openings promote air convection, thereby improving the heat dissipation capacity of the protective cover. At the same time, the double buffer of the baffle, silicone fins and rubber blocks can protect the protective cover and prevent damage to the components inside the charger housing caused by impacts.

[0014] This utility model provides a protective cover for a new energy vehicle charger. A quick-release mechanism is provided on the side of the protective cover and the charger housing. The insertion of the insert and the locking pin achieves mechanical interlocking. Then, the engagement and disengagement of the locking pin and the insert can be controlled by the cooperation of the arc pin and the inclined block, thereby realizing one-button unlocking. Compared with the traditional multi-bolt installation method, it is more convenient. Attached Figure Description
