Detailed Implementation
[0047] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0048] Example 1:
[0049] like Figures 1 to 5 As shown, this utility model provides a terminal cover structure for an electric vehicle controller, including: an electric vehicle controller 1 and metal terminals 2 arranged on the electric vehicle controller 1 for wiring, a protective structure arranged on the metal terminals 2 for wrapping and protecting the metal terminals 2, and a locking structure arranged on the protective structure for locking the opening and closing of the protective structure.
[0050] The protective structure includes a fixed plate 3 fixedly sleeved on the metal terminal 2, a protective cover 301 rotatably sleeved on the fixed plate 3, and a cover plate 302 rotatably installed on the protective cover 301. The cover plate 302 cooperates with the protective cover 301 to wrap the metal terminal 2. Two wire-passing holes 306 are respectively opened inside the protective cover 301 and the cover plate 302 for wire passing. A rotating component is arranged on the protective cover 301 to enable the protective cover 301 to be flipped. The connector of the connecting wire is inserted into the protective cover 301 and aligned with the connection hole on the metal terminal 2. Then, a bolt is used to pass through the connector and screw it into the metal terminal 2 to fix the connecting wire. Then, the cover plate 302 is flipped to wrap the connection between the connector and the metal terminal 2.
[0051] Specifically, the rotating component includes an annular groove 303 inside the fixed plate 3 and a limiting ring 304 arranged inside the protective cover 301. The limiting ring 304 is rotatably installed inside the annular groove 303. When the protective cover 301 rotates, it can drive the limiting ring 304 to rotate within the annular groove 303. The arrangement of the annular groove 303 and the annular groove 304 can prevent the protective cover 301 from detaching from the fixed plate 3.
[0052] Specifically, the rotating assembly also includes a pressing screw 305 threaded inside the protective cover 301 for pressing against the surface of the fixed disk 3 to limit the angle of the protective cover 301. The pressing screw 305 is in contact with the surface of the fixed disk 3. By rotating the pressing screw 305, it can be released from the pressure on the surface of the fixed disk 3, thereby releasing the angle restriction on the protective cover 301. Conversely, when the pressing screw 305 is pressed against the surface of the fixed disk 3, it can fix the current angle of the protective cover 301.
[0053] The locking structure includes an L-shaped hanging rod 4 rotatably mounted on one side of the protective cover 301 and an L-shaped locking rod 401 arranged on one side of the cover plate 302. The L-shaped hanging rod 4 is detachably mounted on the L-shaped locking rod 401. When in use, the L-shaped hanging rod 4 is first flipped to avoid the L-shaped locking rod 401. When the cover plate 302 is flipped to cover the connection between the connector and the metal terminal 2, the cover plate 302 can be locked by flipping the L-shaped hanging rod 4 to hook onto the L-shaped locking rod 401.
[0054] The locking structure also includes a fixed shaft 402 arranged on one side of the protective cover 301 as the fulcrum for the rotation of the L-shaped hanging rod 4. The fixed shaft 402 is rotatably installed inside the L-shaped hanging rod 4. A torsion spring 403 is sleeved on the fixed shaft 402. One end of the torsion spring 403 is arranged on the inner wall of the L-shaped hanging rod 4, and the other end of the torsion spring 403 is arranged on the surface of the fixed shaft 402. When the L-shaped hanging rod 4 is flipped, the torsion spring 403 will be compressed. When the L-shaped hanging rod 4 is released, the compressed torsion spring 403 will be released and drive the L-shaped hanging rod 4 to flip back to its original position.
[0055] Example 2:
[0056] Based on Example 1, in order to further improve the stability of the connecting wire during installation, a compression structure for squeezing and fixing the connecting wire is arranged on the protective structure.
[0057] The extrusion structure includes two threaded seats 5 arranged on one side of the cover plate 302, a flexible plastic strip 501 arranged below the two threaded seats 5, two movable screws 502 respectively threaded inside the two threaded seats 5, and two extrusion plates 503 arranged at one end of the two movable screws 502 for extruding the flexible plastic strip 501. When the cover plate 302 flips to close the protective cover 301, it can drive the flexible plastic strip 501 to press against the connecting line. After the cover plate 302 is locked, the movable screws 502 on both sides can be rotated to drive the extrusion plates 503 to further extrude the flexible plastic strip 501 and press it tightly against the connecting line.
[0058] The extrusion structure also includes a protrusion 504 arranged on one side of the flexible plastic strip 501 to increase friction when pressed against the connecting line. When the flexible plastic strip 501 is extruded, it can drive the protrusion 504 to further press against the connecting line, increase the friction with the connecting line, and improve the fastening effect.
[0059] Working principle: Refer to the wiring instructions. Figure 3 To fix the cable, first adjust the angle between the protective cover 301 and the cover plate 302 according to the direction the connecting cable needs to be laid. During adjustment, rotate the pressure screw 305. The pressure screw 305 moves through its threaded engagement with the protective cover 301, releasing it from the pressure on the surface of the fixing plate 3, thus releasing the angle restriction on the protective cover 301. Then, flip the protective cover 301 to adjust its angle. After adjusting the angle, insert the connector of the connecting cable into the protective cover 301 and align it with the connection hole on the metal terminal 2. Then, use a bolt to pass through the connector and screw it into the metal terminal 2 to fix the connecting cable. The connecting cable rests on the wire hole 306. Next, flip the L-shaped hanging rod 4 to avoid the L-shaped locking rod 401. When the L-shaped hanging rod 4 flips, it rotates on the fixed shaft 402 and compresses the torsion spring 403. Then, the cover plate 302 is flipped to cover the connection between the connector and the metal terminal 2. After the cover plate 302 contacts the protective cover 301, the L-shaped hanging rod 4 can be released. At this time, the compressed torsion spring 403 will be released and drive the L-shaped hanging rod 4 to flip and reset, so that the L-shaped hanging rod 4 hooks onto the L-shaped locking rod 401, locking the cover plate 302 to prevent it from flipping and loosening. At the same time as the cover plate 302 flips to close the protective cover 301, it can also drive the protrusion 504 on the flexible plastic strip 501 to press against the connecting line. After the cover plate 302 is locked, the movable screws 502 on both sides can be rotated. When the movable screws 502 rotate, they can move through the threaded engagement with the threaded seat 5, so that the movable screws 502 drive the extrusion plate 503 to further extrude the flexible plastic strip 501, so that the protrusion 504 on the flexible plastic strip 501 can stick tightly to the connecting line, and reinforce and fix the connecting line.

Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
