Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive engineering, and in particular to a protective cover structure for an OBC power interface with magnetic adsorption. Background Technology
[0002] The OBC power interface is the physical interface connecting the on-board charger to an external power source. It is one of the core components of an electric vehicle charging system. It is responsible for not only safely and efficiently transmitting AC power to the on-board charger during electric vehicle charging, which then converts it into DC power to charge the power battery, but also for signal interaction, safety control, and status monitoring during the charging process.
[0003] If existing OBC power interfaces are not stored properly and are left unattended in the environment, they may be contaminated by dust, metal shavings, or other foreign objects, or be accidentally touched, which may affect the performance of the battery. In addition, in high humidity environments, if the interface is not properly waterproofed and moisture-proofed when not in use, moisture may enter the interface, causing metal parts to rust or short circuits, which may not only affect the normal charging of the battery, but may even cause safety hazards. Utility Model Content
[0004] To overcome the shortcomings of existing OBC power interfaces, which lack effective protection and are easily contaminated by foreign objects, the technical problem to be solved is to provide a protective cover structure for the OBC power interface with magnetic adsorption.
[0005] The technical solution is as follows: A protective cover structure for an OBC power interface with magnetic adsorption includes a battery. Three connecting ropes are evenly distributed laterally on the front side of the battery. One end of each connecting rope is fixedly connected to the battery, and the other end is fixedly connected to a protective shell, with the protective shell corresponding to the position of the connecting rope. Three protective shells are evenly distributed laterally on the front side of the battery corresponding to the battery interface. The two side protective shells are symmetrical about the middle protective shell, which is circular and matches the shape of the battery interface, allowing for a tight cover. A magnetic ring a is fixedly connected inside the protective shell, and a magnetic ring b is fixedly connected to the front interface of the battery. The magnetic ring a and magnetic ring b attract each other, ensuring that the protective shell is securely covered on the battery interface. Three magnetic blocks are evenly distributed laterally on the front side of the battery, with the two side magnetic blocks symmetrical about the middle magnetic block, which is circular. The shape of the magnetic blocks matches the outer contour of the corresponding protective shell, and the magnetic blocks are located below the protective shell. When the protective shell is opened, the magnetic ring a can also attract the magnetic blocks, achieving temporary fixed storage of the protective shell.
[0006] Preferably, the battery also includes a support plate. Three sets of support plates are evenly distributed laterally on the front side of the battery. Each set of support plates consists of two plates, and a screw is rotatably connected between each pair of support plates. A nut is provided on the screw, and the screw and the nut are threadedly connected. By rotating the nut, the nut can move along the screw and press against the protective shell, thereby fixing the protective shell and further enhancing the protective stability.
[0007] Preferably, a buffer pad is also included, with the bottom of the battery fixedly connected to the buffer pad, which can buffer external impact when the battery is placed and protect the internal structure of the battery.
[0008] Preferably, the battery also includes a safety detector, which is installed on the left side of the battery. The battery has a controller inside, which is electrically connected to the safety detector and is used to detect the battery's operating safety status in real time.
[0009] Preferably, the system also includes an alarm, which is mounted on the left side of the battery. The controller is electrically connected to the alarm, and when the safety detector detects an anomaly, the controller controls the alarm to sound an alarm.
[0010] Preferably, the battery also includes a positioning plate, which is evenly distributed laterally on the front side of the battery. The positioning plate is used to position the protective shell during movement. The positioning plate has a groove that matches the shape of the protective shell, which can guide the protective shell to be accurately positioned and prevent it from shifting.
[0011] The beneficial effects of this utility model are as follows: When the operator removes the protective shell, the magnetic ring a inside the protective shell separates from the magnetic block. The connecting rope is moved and stretched by the operator, moving the protective shell to the magnetic ring b at the battery interface. The magnetic ring a and magnetic ring b are attracted and closed, completely covering the interface, thereby preventing the battery interface from being exposed and preventing foreign objects such as dust and moisture from entering. In a humid environment, the sealing structure of the protective shell can effectively block moisture intrusion.
[0012] The operator rotates the screw on the support plate counterclockwise to the appropriate position, and then rotates the nut clockwise to move it along the screw axis and press it against the surface of the protective shell, thereby achieving auxiliary fixation of the protective shell and preventing the magnetic ring a inside the protective shell from detaching from the magnetic block due to vehicle vibration, thus avoiding the protective shell from loosening and affecting subsequent operations.

[0017] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0018] Example: A protective cover structure for an OBC power interface with magnetic adsorption, such as... Figure 1-3 As shown, the device includes a battery 1, connecting ropes 2, a protective shell 3, a magnetic ring a4, a magnetic ring b5, and a magnetic block 6. Three connecting ropes 2 are evenly distributed laterally on the front side of the battery 1. One end of each connecting rope 2 is fixedly connected to the battery 1, and the other end is fixedly connected to the protective shell 3. The protective shell 3 corresponds to the position of the connecting ropes 2. Three protective shells 3 are evenly distributed laterally on the front side of the battery 1, corresponding to the battery 1 interface. The two protective shells 3 on both sides are symmetrical about the middle protective shell 3. The middle protective shell 3 is circular, matching the shape of the battery 1 interface, and can tightly cover the interface. The magnetic ring a4 is fixedly connected inside the protective shell 3. The magnetic ring b5 is fixedly connected to the front interface of the battery 1. The magnetic ring b5 attracts the magnetic ring a4, ensuring that the protective shell 3 is securely covered on the battery 1 interface. Three magnetic blocks 6 are evenly distributed and fixedly connected to the front side of the battery 1. The magnetic blocks 6 on both sides are symmetrical about the middle magnetic block 6. The middle magnetic block 6 is circular. The shape of the magnetic blocks 6 matches the outer contour of the corresponding protective shell 3, and the magnetic blocks 6 are located below the protective shell 3. When the protective shell 3 is opened, the magnetic ring a4 can also attract the magnetic blocks 6 to temporarily fix and store the protective shell 3. The connecting rope 2 is made of nylon elastic material, which can prevent the protective shell 3 from being lost and provide appropriate cushioning and stretching space when opening and closing the protective shell 3. The battery also includes support plates 7, screws 8, and nuts 9. Three sets of support plates 7 are evenly distributed laterally on the front side of the battery 1, with two support plates 7 in each set. A screw 8 is rotatably connected between every two support plates 7. Nuts 9 are provided on the screws 8, and the screws 8 and nuts 9 are threadedly connected. By rotating the nuts 9, they can move along the screws 8 and press against the protective shell 3, thereby fixing the protective shell 3 and further enhancing its protective stability. The battery also includes positioning plates 13, which are evenly distributed laterally on the front side of the battery 1. These positioning plates 13 are used to position the protective shell 3 for movement. The positioning plates 13 have grooves that fit the shape of the protective shell 3.
[0019] When the vehicle needs repair and battery 1 needs replacement, the operator pulls the protective shell 3 away from the battery 1, causing the magnetic ring a4 inside the protective shell 3 to separate from the magnetic ring b5 at the battery 1 interface, stretching the connecting rope 2. Then, the protective shell 3 is rotated downwards to the position of the magnetic block 6, where the magnetic ring a4 attracts the magnetic block 6, and the edge of the protective shell 3 is temporarily fixed by embedding it into the groove of the positioning plate 13. When closing the protective shell 3, the operator rotates it upwards, separating the magnetic ring a4 from the magnetic block 6, and continues to push the protective shell 3 towards the battery 1 interface until the magnetic ring a4 attracts the magnetic ring b5, completing the closure and preventing the battery 1 interface from being exposed. The sealing design between the edge of the protective shell 3 and the battery 1 interface effectively prevents dust and moisture from entering. To prevent loosening due to vibration during vehicle operation, with the protective shell 3 closed, the operator rotates the screw 8 counterclockwise. Initially horizontal, it becomes perpendicular to the surface of the protective shell 3 after rotation. Then, the nut 9 is rotated clockwise, causing it to move axially along the screw 8 and press against the surface of the protective shell 3, providing auxiliary fixation and preventing vibration from causing the magnetic connection to fail. When replacing the battery 1, first loosen it by rotating the nut 9 counterclockwise, then restore the horizontal position by rotating the screw 8 clockwise, and then open the protective shell 3 following the steps described above.
[0020] like Figure 1 As shown, the battery also includes a buffer pad 10, which is fixedly connected to the bottom of the battery 1. It also includes a safety detector 11, which is mounted on the left side of the battery 1. A controller is located inside the battery 1 and is electrically connected to the safety detector 11. Finally, it includes an alarm 12, which is mounted on the left side of the battery 1 and is electrically connected to the controller.
[0021] During use, the buffer pad 10 at the bottom of the battery 1 absorbs vibration energy from road bumps or speed bumps, extending the fatigue life of the battery 1's structural components. The safety detector 11, installed on the left side of the battery 1, collects data from the battery 1 in real time and analyzes and identifies abnormal states through the controller. When an abnormality is detected, the alarm 12, also installed on the left side of the battery 1, immediately sounds an alarm to alert the user and ensure the safe use of the battery 1.
[0022] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that variations may be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
