Description

Technical Field

[0001] This utility model relates to the field of battery rack technology, and more specifically, to a battery rack and a lighting device. Background Technology

[0002] With the increasing variety of electronic devices, power supply methods are also becoming more diverse. To achieve portable and replaceable power, dry cell batteries (such as AA batteries) or rechargeable lithium batteries (such as 26650 batteries) are widely used as energy sources. In practical applications, different batteries have different size specifications, voltage characteristics, and usage scenarios, and users often need to match the batteries to the specifications that come with the device when replacing them.

[0003] Existing battery racks are typically designed for a single type of battery, such as racks for AA dry cell batteries or 26650 lithium batteries, making them incompatible with multiple battery types. This design not only limits user flexibility in choosing between different battery options but also causes inconvenience when the device requires backup power or multiple power source redundancy. If a certain type of battery cannot be replaced in time, the device will be unable to continue supplying power, affecting its practicality and reliability.

[0004] Furthermore, most existing battery racks use fixed mechanical switches to control circuit on / off, lacking intelligent switching capabilities, which is detrimental to multi-power management and automatic circuit control. Therefore, there is an urgent need for a battery rack structure that is compatible with different battery types and has flexible power supply switching capabilities to improve the adaptability of the equipment and the user experience. Summary of the Invention

[0005] To address the problem that existing battery rack structures can typically only accommodate a single type of battery, lacking compatibility and power supply flexibility, this invention provides a battery rack that can simultaneously accommodate different types of batteries and control the circuit switching via magnetic control, aiming to improve the applicability and ease of use of the battery system.

[0011] The first type of battery and the second type of battery can be used to supply power either one or both at the same time. If either battery is missing, the other battery can still independently complete the power supply task.

[0012] The beneficial effects of this technical solution are as follows: This battery rack structure can simultaneously adapt to different types of batteries, such as dry cell batteries and lithium batteries, and realizes intelligent switching of power supply path through magnetic control switch, thereby significantly improving the compatibility, emergency power supply capability and user operation convenience of the battery system, and effectively solving the problem that the existing battery rack can only adapt to a single battery and has poor flexibility.

[0014] According to one embodiment of the present invention, the battery holder further includes a second circuit board and a copper cap. The copper cap is disposed on the second conductive plate and electrically connected to the second circuit board. One end of the copper cap passes through and extends out of the end cap for conductive connection with an external device.

[0015] According to one embodiment of this utility model, the upper cover is provided with a first positioning post, and the end cover is provided with a positioning hole that mates with the first positioning post.

[0016] According to one embodiment of this utility model, the lower cover is provided with a second positioning post, and the end cover is provided with a positioning hole that mates with the second positioning post. The mate between the second positioning post and the positioning hole further improves the positioning effect between the components, ensuring the consistency and reliability of the position of the conductive plate and the battery.

[0017] According to one embodiment of this utility model, the second type of battery is a lithium battery, one end of which is provided with a charging plate, and the charging plate is provided with a charging port, which is exposed outside the battery rack. This design facilitates charging of the lithium battery while it is installed in the battery rack, enabling the lithium battery to be repeatedly charged and discharged.

[0036] like Figure 1-6 As shown, this embodiment discloses a battery rack, including an upper cover 1, a lower cover 2, a first type battery 3, a second type battery 4, and a magnetic switch. The upper cover 1 and the lower cover 2 are arranged opposite to each other and connected by a snap-fit ​​method to form an internally enclosed battery mounting cavity. This cavity is used to accommodate batteries and features a compact structure and good protection performance. Both the first type battery 3 and the second type battery 4 can be detachably installed in this cavity. The first type battery 3 and the second type battery 4 are batteries of different specifications and types, for example, the first type battery 3 is a lithium battery and the second type battery 4 is a dry cell battery, thereby realizing the adaptability of the battery rack to different power sources.

[0037] Furthermore, the lower cover 2 has an internal conductive structure for connecting the first type of battery 3 and the second type of battery 4 to the circuit respectively. This conductive structure includes a first conductive plate 7, a second conductive plate 9, a third conductive plate 10, and electrical connectors, which can effectively lead out the positive and negative terminals of the batteries and connect them to a load or external interface. To achieve intelligent power switching, the battery holder also has a magnetic switch (not shown in the figure). The magnetic switch is preferably located on the conductive plate; in this embodiment, it is located on the second conductive plate 9, while in other embodiments, it is located on the circuit board, the first conductive plate 7, or the third conductive plate 10. The magnetic switch responds to the approach or departure of an external magnet, controlling the circuit's on / off state. Specifically, when a magnet approaches, the magnetic switch is activated, connecting the power supply circuit of a certain battery; when the magnet moves away, the circuit is deactivated, thereby achieving control over at least one of the first type of battery 3 and the second type of battery 4.

[0038] Furthermore, the first type of battery 3 and the second type of battery 4 can be selected to supply power or supply power simultaneously, depending on the user's usage.

[0040] Furthermore, the battery rack has opposing ends. An end cap 5 is located at the beginning of the battery rack, and a first conductive plate 7 is located at the end of the battery rack. The first conductive plate 7 is situated between the upper cover 1 and the lower cover 2 and is respectively inserted into grooves on the inner surfaces of both covers. A charging plate 6 is located between the second type battery 4 and the first conductive plate 7. A third conductive plate 10 is located between the first type battery 3 and the second type battery 4.

[0041] Furthermore, combined Figure 4-5 As shown, the battery holder also includes a second circuit board and a copper cap 8. The copper cap 8 is disposed on the second conductive plate 9 and serves as an electrical contact to transfer electrical energy from the conductive plate to the second circuit board. The copper cap 8 is preferably a hollow cylinder, with one end passing through an end cap 5 and protruding beyond the end cap 5, facilitating connection with external devices to form a standard electrical terminal and improving compatibility with other modules.

[0042] Furthermore, a spring is provided between the copper cap 8 and the second conductive plate 9 to provide elastic contact force when the copper cap 8 is installed, so as to ensure a reliable electrical connection between the copper cap 8 and the second conductive plate 9, and to provide a certain buffering and shock resistance.

[0043] Furthermore, combined Figure 2 As shown, the upper cover 1 is provided with a first positioning post 11, and the end cover 5 is provided with a positioning hole 91 that mates with it. Through the insertion of the post and the hole, precise positioning and stable assembly between the upper cover 1 and the end cover 5 are achieved, preventing misalignment of components during transportation or use. The lower cover 2 is also provided with a second positioning post 21, and the end cover 5 is provided with a positioning hole 91 that mates with the second positioning post 21. The upper and lower covers 2 and the end cover 5 are positioned bidirectionally.

[0044] Specifically, the second type of battery 4 is a lithium battery. One end of the lithium battery is equipped with a charging plate 6, which is fixedly connected to the battery electrodes and used to realize the charging and discharging management of the lithium battery. The charging plate 6 is provided with a charging port 61, which is exposed on the outer surface of the battery rack, so that users can charge the battery through a standard interface without disassembling the battery, thereby enhancing the maintainability and convenience of the lithium battery.

[0045] Furthermore, the charging pad 6 is also provided with a discharge port 62 for outputting electrical energy from the lithium battery or other batteries to an external load. This discharge port 62 is used to connect external mobile devices such as mobile phones, acting as a power bank.

[0046] Combination Figure 7 As shown, in another embodiment, a battery holder with a different shape is provided. Figure 8 The diagram in the middle is a circuit diagram of the battery holder in this embodiment. In the diagram, 3AA is a dry cell battery and 26650 is a type of lithium battery.

[0047] In another embodiment, a lighting device is provided, which serves as the power supply unit for the device. This is achieved through a flexible combination of a first type of battery 3 and a second type of battery 4.
