Description

Technical Field

[0001] This utility model relates to the field of new energy technology, and in particular to a switching mechanism for charging dual-power new energy vehicles. Background Art

[0002] Dual-power switching mechanism for new energy vehicle charging is a technology used in electric vehicles. It allows the vehicle to switch between two different power sources, switching the load circuit from the primary power source to another backup power source to ensure the continuous, safe, and reliable operation of important loads, meet different charging needs, and improve charging flexibility. The reliability of the switching mechanism is related to the accuracy of circuit on / off and the judgment and detection of the original state of the circuit.

[0003] When existing new energy electric vehicles are low on power, they usually go to charging stations to charge. However, it takes a lot of time to fully charge the battery, especially during holidays, when there are queues waiting to charge at highway service areas.

[0004] A search revealed that Chinese Patent Publication No. CN214057265U discloses an automatic backup energy switching device for new energy vehicles. The device includes a deflection switching mechanism that uses the deflection drive of a deflection motor to rotate the electrode head and switch between the first power battery electrode and the second power battery electrode, thereby achieving power electrode switching. By using a motor-driven structure, the rotational cutting and connection can effectively prevent the power electrodes from bridging, avoiding complete disconnection that could lead to power connection failure and preventing damage to the power supply.

[0005] In actual use, the aforementioned switching mechanism requires the electrode tip to continuously contact and rub against the power electrode rod when switching power supply via the deflection switching mechanism. After long-term use, the electrode tip will wear out, making it impossible to maintain a tight fit with the power electrode rod, thus causing the power supply switching to fail. This has certain defects. To address these issues, a dual-power switching mechanism for charging new energy vehicles is proposed. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides a switching mechanism for charging dual-power new energy vehicles. It aims to solve the technical problem that new energy electric vehicles need to go to charging stations to charge when their power is insufficient, which takes a lot of time, especially during holidays when many people have to queue to charge the new energy vehicles. It also improves the problem that the electrode tip of the existing technology will wear down and cause switching failure when switching power supply through the deflection switching mechanism.

[0007] To achieve the above objectives, this utility model adopts the following technical solution: a switching mechanism for charging dual-power new energy vehicles, comprising a power bank body and a switching box installed inside the power bank body. A cover plate is detachably connected to the top of the switching box. An electrode power supply terminal block is fixedly connected to the left side surface of the switching box.

A power supply electrode rod is fixedly connected to the left side surface of the power supply terminal block. A fixing plate is fixedly connected to the outer side surface of the power supply electrode rod. A bonding block is fixedly connected to the right side of the upper surface of the output electrode rod. A circular plate is provided above the bonding block. A rotating unit is provided above the circular plate, which drives the circular plate to rotate. A rotating rod is rotatably connected to the bottom surface of the circular plate.

[0008] As a further description of the above technical solution:

[0009] The power supply terminals and the power supply electrode rod, both located near the center of the switching box, extend through the switching box. The right end of the rotating rod is arranged in a triangular structure.

[0010] As a further description of the above technical solution:

[0012] As a further description of the above technical solution:

[0013] The power supply terminals are two in number, and the two power supply terminals are fixedly connected to the right side surface of the switching box in a linear array. The right end of the fixing plate is fixedly connected to the right inner wall surface of the switching box.

[0014] As a further description of the above technical solution:

[0015] The upper surface of the switching box is provided with a guide groove, the bottom surface of the cover plate is fixedly connected with a guide rod, and the outer side of the cover plate is fixedly connected with a side plate, which is fixedly connected to the switching box by bolts.

[0023] 1. In this utility model, through the cooperation of the fixed plate, the bonding block, the circular plate, the rotating unit, the rotating rod and the limiting unit, after the power supply switching is completed, the spring is compressed to generate elastic potential energy and act on the rotating rod. When the rotating rod wears or deforms during long-term use, it can still maintain contact with the power electrode rod under the action of the elastic potential energy of the spring, avoiding wear of the electrode tip, which would prevent it from being unable to fit tightly with the power electrode rod, thus causing the power supply switching to fail.

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] Reference Figure 1 The new energy vehicle has a location in the rear compartment for storing the power bank 16, and this location is equipped with a line that connects to the power battery of the new energy vehicle. The owner can connect the power bank 16 to the line in the service area to achieve an electrical connection between the power battery of the new energy vehicle and the power bank 16.

[0035] This utility model provides an embodiment of a switching mechanism for charging dual-power new energy vehicles, comprising a power bank 16 body and a switching box 1 installed inside the power bank 16 body. A cover plate 2 is detachably connected to the top of the switching box 1. An electrode power supply terminal row 3 is fixedly connected to the left side surface of the switching box 1, and an output electrode rod 4 is fixedly connected to the right side surface of the electrode power supply terminal row 3. Two power supply terminals 5 are fixedly connected to the right side surface of the switching box 1 in a linear array. A power electrode rod 6 is fixedly connected to the left side surface of the power supply terminals 5. The ends of the power supply terminals 5 and the power electrode rod 6 near the center of the switching box 1 both penetrate through the switching box 1. The switching of the electrodes is achieved by the overlapping and switching of the two power supply terminals 5 with a rotating rod 10, thus realizing the switching of the power electrodes. The rotation cutting and connection can effectively prevent electric shock. The connection between the source electrodes avoids incomplete disconnection leading to power continuity and prevents damage to the power supply. The new energy vehicle is designed with a charging terminal. When the new energy vehicle's own power supply is insufficient, the power bank 16 is plugged into the vehicle's charging terminal to provide power through the battery or the power bank 16. The new energy vehicle is designed with dual power supplies: the first power battery 18 and the second power battery 19 independently power the vehicle. The first power battery 18 and the second power battery 19 are connected to the two power supply terminals 5 respectively. The new energy vehicle is designed with a charging terminal. When the first power battery 18 is low on power, the second power battery 19 acts as the vehicle's power source, and the power bank 16 charges the first power battery 18. When the first power battery 18 is fully charged and the second power battery 19 is low on power, the first power battery 18 acts as the vehicle's power source, and the power bank 16 charges the second power battery 19.

[0036] There are three ways to connect the new energy vehicle and the power bank 16. The first way is that the new energy vehicle is designed with a power cord 17, and the new energy vehicle connects to the power bank 16 through the power cord 17, which is designed for easy connection. The second way is that the power bank 16 is designed with a power cord 17, and the power bank 16 connects to the charging terminal of the car through the power cord 17, which is designed for easy connection. The third way is that both the new energy vehicle and the power bank 16 are designed with power cords 17, and the power cords 17 of the new energy vehicle and the power bank 16 are connected to each other, which is designed to improve safety.

[0037] Reference Figure 2A fixing plate 7 is fixedly connected to the outer surface of the power electrode rod 6. The right end of the fixing plate 7 is fixedly connected to the inner right wall surface of the switching box 1. The fixing plate 7 can enhance the strength of the power electrode rod 6 and prevent the power electrode rod 6 from bending during continuous power switching, which would affect the service life of the power electrode rod 6 and the power switching connection effect. The switching structure can be used for the connection between the first power battery 18, the second power battery 19 and the car, and can also be used for the connection between the first power battery 18, the second power battery 19 and the power bank 16.

[0038] Reference Figures 3-4 A bonding block 8 is fixedly connected to the right side of the upper surface of the output electrode rod 4. The right side of the bonding block 8 is set in a concave arc-shaped structure. A circular plate 9 is set above the bonding block 8. A rotating unit is set above the circular plate 9. The rotating unit includes a motor 91. The motor 91 is fixedly connected to the upper surface of the cover plate 2. The bottom output end of the motor 91 passes through the cover plate 2. A rotating shaft 92 is fixedly connected to the bottom output end of the motor 91. The bottom end of the rotating shaft 92 is fixedly connected to the center of the upper surface of the circular plate 9. When the motor 91 starts, it can drive the circular plate 9 to rotate through the rotating shaft 92. A rotating rod 10 is rotatably connected to the bottom surface of the circular plate 9. When the circular plate 9 rotates, it can drive the rotating rod 10 to move synchronously.

[0039] The left side surface of the rotating rod 10 is in contact with the right side surface of the bonding block 8. When the circular plate 9 drives the rotating rod 10 to rotate, the contact state between the rotating rod 10 and the bonding block 8 will not change, ensuring the electrical connection effect between the rotating rod 10 and the output electrode rod 4. The right end of the rotating rod 10 is set in a triangular structure, and both the front and rear ends of the right side surface of the rotating rod 10 are set in an inclined structure, which can increase the contact area between the rotating rod 10 and the power electrode rod 6 after the rotating rod 10 rotates, making the connection between the rotating rod 10 and the power electrode rod 6 more stable and maintaining the stability when the electrode is connected.

[0040] A limiting unit is provided on the outer side of the rotating rod 10. The limiting unit includes two limiting plates 101, which are fixedly connected to the front and rear sides of the bottom surface of the circular plate 9, respectively. A spring 102 is fixedly connected to the surface of the limiting plate 101 near the rotating rod 10. The end of the spring 102 away from the limiting plate 101 is in contact with the outer wall of the rotating rod 10. When the circular plate 9 rotates, the spring 102 and the limiting plate 101 can provide support force to the rotating rod 10, so that the rotating rod 10 rotates with the circular plate 9. When the rotating rod 10 is in contact with the power electrode rod 6, the power supply... The electrode rod 6 limits the movement of the rotating rod 10, causing it to stop. However, as the circular plate 9 continues to rotate, it compresses the spring 102, which rotates in the opposite direction. This compression generates elastic potential energy, which acts on the rotating rod 10. Even when the rotating rod 10 wears or deforms during long-term use, it can still maintain contact with the power electrode rod 6 under the action of the elastic potential energy of the spring 102. This prevents wear on the electrode tip, which could lead to a failure to maintain a tight contact with the power electrode rod 6 and thus power switching failure.

[0041] Reference Figure 3 and Figure 6 The upper surface of the switching box 1 is provided with a guide groove 12, and the bottom surface of the cover plate 2 is fixedly connected with a guide rod 13. The guide rod 13 is inserted into the guide groove 12. When the guide rod 13 is inserted into the guide groove 12, it can initially limit the cover plate 2, so that the cover plate 2 is stably placed above the switching box 1. The outer side of the cover plate 2 is fixedly connected with a side plate 14. The side plate 14 is fixedly connected to the switching box 1 by bolts 15, which can fix the cover plate 2. The outer wall surface of the switching box 1 is provided with screw holes corresponding to the bolts 15. When the guide rod 13 is fully inserted into the guide groove 12, the bolts 15 will automatically align with the screw holes, and the cover plate 2 will not shift when the bolts 15 are tightened. When it is necessary to inspect and maintain the internal components of the switching box 1, the bolts 15 can be unscrewed to release the limitation on the cover plate 2, making it easy to disassemble the cover plate 2. The operation is simple and convenient for maintenance.

[0042] Working principle: When switching the connection between the first and second power batteries 19 and the car or between the first and second power batteries 19 and the power bank 16 is required, the starter motor 91 drives the circular plate 9 to rotate, which in turn drives the rotating rod 10 to rotate. Under the limitation of the springs 102 on both sides, the rotating rod 10 quickly completes the contact with the power electrode rod 6 corresponding to the other power source, completing the switching. The rotation cuts off and connects effectively to prevent the overlap between the power electrodes, avoiding the power connection caused by complete cut-off. After the rotating rod 10 is in contact with the power electrode rod 6, as the circular plate 9 continues to rotate, it will compress the spring 102 in the opposite direction of the rotation of the circular plate 9, causing the spring 102 to compress and generate elastic potential energy. At this time, the elastic potential energy of the spring 102 acts on the rotating rod 10. When the rotating rod 10 wears or deforms during long-term use, it can still maintain contact with the power electrode rod 6 under the action of the elastic potential energy of the spring 102.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
