Description

Technical Field

[0001] This utility model relates to the field of battery connection technology, and in particular to a non-contact battery pack power identification and electrical output control system. Background Technology

[0002] With the widespread use of portable devices such as power tools, garden tools, and home appliances, detachable battery packs have become increasingly common. To meet the power requirements of different devices, battery packs with various output power specifications are available on the market, such as high-output power battery packs and standard-output power (low-output power) battery packs.

[0003] While high-output power battery packs can provide greater current and power to meet the demands of high-performance devices, they are also more expensive. If users mistakenly use low-power battery packs in high-power-demand devices, they will force the packs to operate under overload conditions, leading to overheating, a drastically shortened lifespan, and even safety risks. Conversely, using high-power battery packs in low-power devices will prevent them from fully utilizing their performance advantages, resulting in wasted resources.

[0004] Currently, common methods to prevent misuse often employ physical structures to prevent incorrect insertion (such as different shaped connectors). However, these methods can only prevent battery packs with different voltage platforms from being interlocked, and cannot distinguish between battery packs with different discharge capacities under the same voltage platform.

[0005] Therefore, in view of the shortcomings of the existing technology, it is necessary to design a non-contact battery pack power identification and electrical output control system to solve the above problems.

[0006] It should be noted that the above introduction to the technical background is only for the purpose of providing a clear and complete explanation of the technical solution of this utility model and facilitating the understanding of those skilled in the art. It should not be assumed that the above content is known to those skilled in the art simply because it has been described in the background section of this utility model. Utility Model Content

[0007] To overcome the shortcomings of the prior art, the present invention aims to disclose a non-contact battery pack power identification and electrical output control system, which is used to automatically determine the power type of the inserted battery pack and control the electrical appliances to operate within a safe power limit.

[0008] This utility model discloses a non-contact battery pack power identification and electrical output control system, comprising:

[0009] The battery pack assembly includes a high-output power battery pack and a low-output power battery pack. The high-output power battery pack has a magnetic attraction structure at its plug-in end, while the low-output power battery pack does not have a magnetic attraction structure at its plug-in end.

[0010] An electrical component includes a battery compartment of the electrical appliance and a connector located within the battery compartment. The connector is used for electrical and mechanical connection with the connector end of the battery pack assembly. A micro switch is provided on the connector at a position corresponding to the magnetic structure. The triggering state of the micro switch is controlled by the magnetic force of the magnetic structure.

[0011] The micro switch is electrically connected to the output control circuit inside the appliance, and the output control circuit is configured as follows:

[0012] When the microswitch is triggered, the controlled electrical appliance operates at the first power limit.

[0013] When the micro switch is not triggered, the controlled electrical appliance operates at the second power limit.

[0014] The first power limit is higher than the second power limit.

[0015] Preferred technical solution: The magnetic attraction structure is a permanent magnet, which is embedded inside the plug-in housing of the high-output power battery pack.

[0016] Preferred technical solution: The micro switch is either a reed switch or a reed contact mechanical micro switch.

[0017] Preferred technical solution: The output control circuit includes a power limiting module, and the signal output terminal of the micro switch is connected to the signal receiving terminal of the power limiting module; when the micro switch is not triggered, the power limiting module works to limit the output power of the appliance to the second power limit.

[0018] Preferred technical solution: The electrical component is also provided with an indicator light, which is electrically connected to a micro switch and is configured to indicate the type of battery pack currently in use based on the trigger state of the micro switch.

[0019] Preferred technical solution: The connector is equipped with an anti-misinsertion structure to ensure that the battery pack is inserted in only one direction. This ensures that the magnetic structure can accurately align with the microswitch.

[0020] Due to the application of the above technical solution, the beneficial effects of this utility model compared with the prior art are as follows:

[0021] This invention employs a non-contact magnetic induction identification principle. By incorporating a permanent magnet into a high-power battery pack and utilizing a microswitch within the electrical appliance, it achieves automatic and reliable identification of the battery pack's power rating. This avoids mechanical contact wear and oxidation issues, resulting in a long lifespan and high reliability for the battery pack power identification system. The system fundamentally prevents low-power battery packs from being overloaded, completely eliminating safety hazards such as overheating and damage, ensuring superior safety. The overall structure is simple, requiring only the addition of a permanent magnet and a microswitch, making it extremely cost-effective. The system achieves instant identification upon insertion, requiring no user intervention, and provides intuitive feedback through indicator lights, making operation convenient.

[0034] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model discloses a non-contact battery pack power identification and electrical output control system, which mainly includes a battery pack assembly and an electrical component 3. The main components of this utility model will be described in detail below:

[0035] The battery pack assembly includes two types: a high-output-power battery pack 1 and a low-output-power battery pack 2. A magnetic attraction structure 11 is embedded inside the connector housing of the high-output-power battery pack 1; in this embodiment, the magnetic attraction structure 11 is a permanent magnet. However, no magnetic attraction structure 11 is provided at the connector of the low-output-power battery pack 2.

[0036] Electrical component 3 includes a battery compartment 31 for housing a battery pack, and a connector 32 is fixedly installed inside the battery compartment 31. The connector 32 is used to couple with the connector end of the battery pack to achieve power transmission and mechanical locking. A micro switch 33 is installed at a specific position on the connector 32. In this embodiment, the micro switch 33 is preferably a reed switch. The position of the reed switch needs to meet the requirement that when the high-output power battery pack 1 is correctly inserted, its internal magnetic attraction structure 11 can be precisely aligned with the reed switch, and the magnetic force will close its contacts, thus triggering it.

[0037] The signal output terminal of the micro switch 33 is electrically connected to the output control circuit inside the appliance. The output control circuit is configured as follows:

[0038] When the micro switch 33 is triggered, the controlled electrical appliance operates at the first power limit.

[0039] When the micro switch 33 is not triggered, the control appliance operates at the second power limit.

[0040] The first power limit is higher than the second power limit.

[0041] It should be noted that the aforementioned "electrical appliances" are not limited to... Figure 3 The types of electrical appliances shown are not limited to those compatible with high-output-power battery pack 1 and low-output-power battery pack 2; they can be used with any type of electrical appliance. This solves the problem of identifying appliances switching between different output-power battery packs.

[0042] In some embodiments, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the connector 32 is also provided with an anti-misinsertion structure 4. In this embodiment, the anti-misinsertion structure 4 is an asymmetrical groove and guide rail, which ensures that the battery pack can only be inserted in one direction, thus ensuring the accuracy of the alignment.

[0043] In some embodiments, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the output control circuit includes a power limiting module, and the signal output terminal of the micro switch 33 is connected to the signal receiving terminal of the power limiting module. When the micro switch 33 is not triggered, the power limiting module works and limits the output power of the appliance to the second power limit. When the micro switch 33 is triggered, the output power of the appliance is limited to the first power limit.

[0044] The method and principle of this utility model are as follows: When the high-output-power battery pack 1 is inserted, the magnetic structure 11 inside the battery pack approaches the micro switch 33. The magnetic force of the magnetic structure 11 causes the contacts inside the micro switch 33 to close, triggering the micro switch 33 and outputting an identification signal to the output control circuit inside the appliance. Upon receiving this signal, the output control circuit determines that a high-power battery pack is connected and immediately controls the power limiting module to not operate or sets a higher current threshold, allowing the appliance to operate at its maximum performance, i.e., the first power limit. Simultaneously, it can drive an indicator light to emit a green light, indicating to the user that a high-power battery pack is currently being used. It should be noted that the color of the indicator light can be freely set.

[0045] When the low-output-power battery pack 2 is inserted, since there is no magnetic material at the battery pack connector and no magnetic field near the microswitch 33, its contacts remain open. The microswitch 33 is not triggered, and the internal output control circuit of the appliance maintains the power limiting module in the activated state, limiting the appliance's output current or power to a preset safe value, i.e., operating at the second power limit, thereby protecting the battery pack from over-discharge. Simultaneously, it can drive the indicator light to emit a red light, reminding the user that the power is limited.

[0046] In summary, this utility model achieves automatic and non-destructive identification of battery pack power levels and intelligent control of electrical output through a simple mechanism of magnetically controlled microswitches, combining high performance, high safety, and high economy.

[0047] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are 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.
