Description

Technical Field

[0001] The utility model relates to the technical field of miniature circuit breakers, and more specifically, to an intelligent miniature circuit breaker. Background Art

[0002] The intelligent miniature circuit breaker for electric bicycles is an electrical protection device that integrates miniature circuit breakers and intelligent control functions. It is commonly used in the circuits of electric bicycles to protect the circuits from overload, short circuit and other electrical faults.

[0003] Compared with traditional circuit breakers, it is compact and suitable for installation in electric bicycles with limited space. During the assembly process, the side wiring slot is opened by rotating the locking bolt to achieve connection, and then the locking bolt is used to lock the wiring. However, the electric bicycle will produce bumps during driving, causing the circuit breaker itself to vibrate. If the locking bolt becomes loose, the connecting wire harness will become loose. At the same time, bent connecting wires can easily cause poor contact or even fall off, causing harm to the rider. Therefore, professionals in this field provide an intelligent miniature circuit breaker to solve the above-mentioned problems. Utility Model Content

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0020] See also Figures 1 to 3 In the utility model, an intelligent miniature circuit breaker comprises a circuit breaker body 1 and wiring grooves 2 provided on both sides, two mounting grooves 3 are provided on the top of the circuit breaker body 1, and locking bolts 4 are connected to the internal threads of the mounting grooves 3, and two movable frames 5 are detachably connected to the top of the circuit breaker body 1, and a shielding plate 6 is slidably connected to the inner wall of the movable frame 5, and magnets 7 are fixedly installed on both sides of the shielding plate 6, and two metal sheets 8 are connected to the inner wall of the movable frame 5, and the two metal sheets 8 are respectively located on the left and right sides of the shielding plate 6, and the left and right sides of the circuit breaker body 1 are detachably connected to the mounting frame 9, and the wiring groove 2 is located inside the mounting frame 9, and two arc-shaped card blocks 10 are slidably connected to the inner wall of the mounting frame 9, and the two arc-shaped card blocks 10 are respectively located at the top and the bottom of the wiring groove 2, and a locking screw rod 11 is rotatably connected to the inner wall of the mounting frame 9, and the two arc-shaped card blocks 10 are both threadedly connected to the locking screw rod 11.

[0021] An arc-shaped groove is formed on the arc-shaped clamping block 10, and evenly distributed protrusions are connected to the inner wall of the arc-shaped groove.

[0022] The intelligent miniature circuit breaker is applied to the battery assembly of the electric bicycle. When the wiring harness needs to be connected, the user slides the shielding plates 6 on both sides to the side of the movable frame 5 away from the locking bolt 4, so that the metal sheet 8 contacts the magnet 7 and the installation groove 3 is exposed. Then the user turns the locking bolt 4 inside the installation groove 3 to connect through the wiring groove 2. The user inserts the end of the connecting wire into the wiring groove 2 and then rotates the locking bolt 4 to lock the connecting wire harness with the bolt. Then the user slides the shielding plate 6 so that the shielding plate 6 moves to the other side to cover the locking bolt 4. Then the user turns the locking screw 11 so that the two arc-shaped blocks 10 threadedly connected to the locking screw 11 move toward the connecting wire harness. As the arc-shaped block 10 continues to rotate, the arc groove of the arc-shaped block 10 fits with the connecting wire, and cooperates with the protective protrusion to limit the end of the connecting wire harness.

[0023] In the utility model, by arranging a slidable shielding plate 6 on the top of the locking bolt 4, the bolt can be effectively prevented from loosening due to long-term bumps, thereby ensuring the stable connection of the wiring harness, reducing the poor contact or falling off problems caused by vibration, and also playing a certain dust and moisture-proof role, extending the service life of the circuit breaker. At the same time, the connecting wire end is clamped by the arc-shaped clamping block 10, which can reduce the poor contact caused by bending, thereby reducing the maintenance frequency and difficulty. The stable connection can avoid circuit failures caused by wiring harness falling off or poor contact, reduce potential safety hazards, and ensure the safety of the rider.

[0024] See also Figure 1 and 2, wherein: a finger groove 12 is provided on the top of the shielding plate 6, and evenly distributed anti-slip grooves are provided on the inner wall of the finger groove 12.

[0025] In the present invention, when the user needs to slide the shielding plate 6, the finger groove 12 can provide a fulcrum for the user, and the anti-slip pattern can prevent the friction of the fingers from increasing and prevent the hands from slipping.

[0026] See also Figure 1 and 2 , wherein: two guide grooves 13 are provided on the inner wall of the movable frame 5 , and the shielding plate 6 is slidably connected to the guide grooves 13 .

[0027] In the present invention, the setting of the guide groove 13 can limit the shielding plate 6, so that the shielding plate 6 always maintains stable movement in the horizontal direction.

[0028] See also Figure 1 and 3 , wherein: a guide shaft 14 is fixedly connected to the inner wall of the mounting frame 9 , and the two arc-shaped blocks 10 are both slidably connected to the guide shaft 14 .

[0029] In the present invention, the setting of the guide shaft 14 can limit the arc-shaped clamping block 10, so that the arc-shaped clamping block 10 is always located inside the installation frame 9 to maintain stable movement in the vertical direction.

[0030] See also Figure 1 and 3 , wherein: the locking screw rod 11 is connected with a knob 15, and the knob 15 is polygonal in shape when viewed from above.

[0031] In the utility model, when the user needs to rotate the locking screw 11, the knob 15 can provide a fulcrum for the user, and the knob 15 with multiple sets of sides can be easily rotated by a tool to make the arc-shaped block 10 fit better with the wiring harness.

[0032] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
