Description

Technical Field

[0001] This utility model relates to the field of circuit packaging, specifically to a circuit packaging structure for a replaceable battery. Background Technology

[0002] With the widespread use of wearable devices, many garments and footwear are equipped with light-emitting components, especially for children and users with specific needs (such as night running).

[0003] Figure 1 The prior art illustrates an LED shoe light installed on a shoe. The LED shoe light includes a casing 101, a battery 102, an IC chip 103, several connecting wires 104, an interface LED light 105, and a vibration sensor 106. The battery 102, IC chip 103, and vibration sensor 106 are all housed within the epoxy resin casing 101, thus isolating them from the outside environment, providing waterproofing and dustproofing to extend their lifespan. The IC chip 103 is connected to both the battery 102 and the vibration sensor 106. One end of each of the connecting wires 104 is connected to the IC chip 103, and the other end of each connecting wire is connected to the interface LED light 105. The LED shoe light can be controlled by the vibration sensor 106 to turn the interface light on and off, or it can be manually controlled to turn the interface light on and off.

[0004] because Figure 1 The LED shoe light encapsulates the battery 102, IC chip 103, and vibration sensing device 106 together within an epoxy resin sleeve 101. Therefore, the LED shoe light is a disposable component, and the battery 102 cannot be replaced. During shoe use, there may be situations where the shoe is still usable but the LED shoe light has stopped illuminating. Furthermore, with the increasing environmental protection requirements for battery products worldwide, most countries require that battery waste be separately removed from the product (shoe) for environmentally friendly disposal. Figure 1 The battery 102 is obviously difficult to separate from the rigid casing 101, which does not meet the relevant product requirements and must be improved. Utility Model Content

The connection point of the thin conductor and the thick conductor is located in the fixing cavity of the electrical connector.

[0010] In a preferred embodiment, the thick conductor is a conductive sheet.

[0011] In a preferred embodiment, the circuit board is encapsulated within the circuit board encapsulation cavity via a potting encapsulation structure; and / or,

[0012] The electrical connector in the electrical connector fixing cavity is fixed in the electrical connector fixing cavity by a potting encapsulation structure.

[0013] In a preferred embodiment, the circuit board is encapsulated in the circuit board encapsulation cavity by a structure for injecting light-curing adhesive; the electrical connector in the electrical connector fixing cavity is fixed in the electrical connector fixing cavity by a structure for injecting silicone or hot melt adhesive.

[0014] In a preferred embodiment, the circuit board encapsulation cavity, the electrical connector fixing cavity, and the battery compartment are arranged side by side, with the electrical connector fixing cavity located in the middle of the circuit board encapsulation cavity and the battery compartment, and the electrical connector fixing cavity adjacent to the circuit board encapsulation cavity.

[0015] In a preferred embodiment, the electrical connector fixing cavity is located on one side or in the center of the middle position between the circuit board encapsulation cavity and the battery compartment.

[0020] The beneficial effects of this utility model are as follows: In this embodiment, a separate electrical connector fixing cavity is provided, and the electrical connector in the electrical connector fixing cavity is fixed in the electrical connector fixing cavity.

[0033] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and the accompanying drawings. However, those skilled in the art will understand that this utility model is not limited to the accompanying drawings and the following embodiments.

[0034] This utility model provides a circuit packaging structure for a replaceable battery. The circuit packaging structure includes a circuit board, an electrical connector, a circuit board packaging cavity, an electrical connector fixing cavity, and a battery compartment. The circuit board is packaged within the circuit board packaging cavity. The electrical connector includes a first polarity connector and a second polarity connector. A first end of the first polarity connector is electrically connected to a first polarity end of the circuit board in the circuit board packaging cavity, and a second end of the first polarity connector extends out of the circuit board packaging cavity, passes through the electrical connector fixing cavity, and is electrically connected to or forms the first polarity end of the battery compartment. A first end of the second polarity connector is electrically connected to a second polarity end of the circuit board in the circuit board packaging cavity, and a second end of the second polarity connector extends out of the circuit board packaging cavity, passes through the electrical connector fixing cavity, and is electrically connected to or forms the second polarity end of the battery compartment. The battery compartment is used for removably installing a battery, and the first and second polarity ends of the battery compartment are used for electrical contact with the positive and negative terminals of the battery. The electrical connector in the electrical connector fixing cavity is fixed within the electrical connector fixing cavity.

[0035] like Figures 2a-2d As shown in the first embodiment of this utility model, a circuit packaging structure for a replaceable battery is provided. The circuit packaging structure for the replaceable battery includes a circuit board 1, an electrical connector 2, a circuit board packaging cavity 3, an electrical connector fixing cavity 4, and a battery compartment 5.

[0036] The circuit board 1 can be a single-sided, double-sided, or multi-layer circuit board, integrating a controller, electronic components, and wires to achieve corresponding electrical functions. The circuit board 1 is powered by an external power supply and has a first polarity terminal and a second polarity terminal. To prevent water and dust damage and extend the lifespan of the circuit board, the circuit board 1 is encapsulated in the circuit board encapsulation cavity 3. The encapsulation method preferably employs potting encapsulation, such as using a light-curing adhesive, for example, epoxy resin.

[0037] In this preferred embodiment, the electrical connector fixing cavity 4 is disposed between the circuit board packaging cavity 3 and the battery compartment 5, that is, the circuit board packaging cavity 3, the electrical connector fixing cavity 4, and the battery compartment 5 are arranged side by side, with the electrical connector fixing cavity 4 located in the middle of the circuit board packaging cavity 3 and the battery compartment 5. Of course, other layouts can also be adopted among the circuit board packaging cavity 3, the electrical connector fixing cavity 4, and the battery compartment 5. For example, the circuit board packaging cavity 3 and the battery compartment 5 can be stacked, and the electrical connector fixing cavity 4 can be placed on the side of the circuit board packaging cavity 3 and the battery compartment 5.

[0038] The battery compartment 5 has a sealed space for removably installing a battery, such as a button cell battery (not shown). In this embodiment, the battery compartment 5 includes a detachably connected lower housing 51 and an upper cover 52, the upper cover 52 being rotatably and sealingly connected to the lower housing 51. The outer edge of the upper cover 52 has at least two protrusions 53 (…). Figure 2c (There are two in the middle). The inner sidewall of the lower housing 51 is provided with a rotating groove 54 corresponding to the protrusion 53. The protrusion 53 of the upper cover 52 can be inserted into the inner edge of the lower housing 51 and rotated unidirectionally into the rotating groove 54, thereby pressing and fixing the battery in the cavity of the battery compartment 5. When it is necessary to remove the battery, the upper cover 52 can be rotated in the opposite direction to remove it from the lower housing 51 and remove the battery. In order to facilitate the rotation of the upper cover 52, a rotating slot 55 is also provided on the upper surface of the upper cover 52. In order to form a sealed space, a sealing strip can be provided on the upper cover 52 or the lower housing 51. In this embodiment, the sealing strip is provided on the flange of the upper cover 52.

[0039] The battery compartment 5 has a first polarity terminal (positive terminal in this embodiment) and a second polarity terminal (negative terminal in this embodiment) for electrical contact with the positive and negative terminals of the battery. The first polarity terminal and the second polarity terminal of the battery compartment 5 are respectively located on the side wall and / or bottom wall of the battery compartment 5, depending on the battery model that the battery compartment 5 is compatible with.

[0040] The electrical connector 2 includes a first polarity electrical connector 21 and a second polarity electrical connector 22.

[0041] The first end of the first polarity connector 21 is electrically connected to the first polarity end (positive end in the figure) of the circuit board 1 in the circuit board encapsulation cavity 3. The second end of the first polarity connector 21 extends out of the circuit board encapsulation cavity 3, passes through the connector fixing cavity 4, and is electrically connected to or forms the first polarity end of the battery compartment 5. That is, the battery compartment 5 has a first polarity end, and the second end of the first polarity connector 21 is electrically connected to the first polarity end of the battery compartment 5, or the second end of the first polarity connector 21 directly forms the first polarity end of the battery compartment 5.

[0042] The first end of the second polarity electrical connector 22 is electrically connected to the second polarity end (negative end in the figure) of the circuit board 1 in the circuit board encapsulation cavity 3. The second end of the second polarity electrical connector 22 extends out of the circuit board encapsulation cavity 3, passes through the electrical connector fixing cavity 4, and is electrically connected to or forms the second polarity end of the battery compartment 5. That is, the battery compartment 5 has a second polarity end, and the second end of the second polarity electrical connector 22 is electrically connected to the second polarity end of the battery compartment 5, or the second end of the second polarity electrical connector 22 directly forms the second polarity end of the battery compartment 5.

[0043] To ensure the connection strength of the electrical connector 2 between the circuit board 1 and the battery compartment 5, a separate electrical connector fixing cavity 4 is provided in this embodiment of the invention to fix the electrical connector 2 in the electrical connector fixing cavity 4. Since the relative position between the electrical connector fixing cavity 4 and the circuit board encapsulation cavity 3 where the circuit board 1 is placed remains unchanged, the electrical connector 2 between the circuit board 1 and the battery compartment 5 will not deform or twist during use, ensuring a stable connection.

[0044] The electrical connector 2 can be a wire. In a preferred embodiment, the electrical connector 2 includes a thin conductor 23 and a thick conductor 24 connected together. One end of the thin conductor 23 is connected to the circuit board 1, and one end of the thick conductor 24 forms a first polarity terminal or a second polarity terminal of the battery compartment 5. The connection point of the thin conductor 23 and the thick conductor 24 is located in the electrical connector fixing cavity 4. Thus, while fixing the electrical connector 2 in the electrical connector fixing cavity 4, the connection point of the thin conductor 23 and the thick conductor 24 is also fixed in the electrical connector fixing cavity 4, improving the connection strength of the connection point. Furthermore, the use of a thick conductor increases the strength of the electrical connector 2 extending into the battery compartment 5, ensuring the stability of the electrical equipment. In this embodiment, the thick conductor is preferably a conductive sheet.

[0045] Furthermore, since the electrical connector retaining cavity 4 is only suitable for fixing the electrical connector 2 that passes through it, the electrical connector retaining cavity 4 does not need to occupy an excessively large area. Especially when using potting encapsulation for fixation, the smaller electrical connector retaining cavity 4 can reduce the amount of potting glue (such as silicone or hot melt glue) used. In this embodiment, the electrical connector retaining cavity 4 is located on one side at the middle position between the circuit board encapsulation cavity 3 and the battery compartment 5.

[0046] In a preferred embodiment of this invention, the electrical connector fixing cavity 4 is adjacent to the circuit board encapsulation cavity 3. Using potting (silicone or hot melt adhesive) encapsulation, the circuit board 1 is encapsulated within the circuit board encapsulation cavity 3, and the connection point of the thin conductor 23 and the thick conductor 24 is encapsulated within the electrical connector fixing cavity 4. This ensures a secure connection between the circuit board 1 and the electrical connector 2, while also providing dust and water protection and extending service life. The thick conductor 24 extends from the electrical connector fixing cavity 4 into the battery compartment 5, forming a first polarity terminal and a second polarity terminal, further ensuring electrical connection strength. Furthermore, the battery compartment employs a sealed design, ensuring that the overall performance of the circuit components remains essentially consistent with existing technologies.

[0047] like Figures 3a-3d As shown in the second embodiment of this utility model, another circuit packaging structure for a replaceable battery is shown. The circuit packaging structure for the replaceable battery includes a circuit board 1, electrical connectors 21 and 22, a circuit board packaging cavity 3, an electrical connector fixing cavity 4, and a battery compartment 5.

[0048] Compared with the first embodiment, the sealing structure of the battery compartment 5 in this embodiment is different. The following description only describes the structure of the battery compartment 5 in the second embodiment; other structures that are the same as those in the first embodiment will not be described again.

[0049] The battery compartment 5 includes a detachably connected lower housing 51 and an upper cover 52, with the upper cover 52 securely fastened to the lower housing 51. Specifically, the upper cover 52 has a first protrusion 56 and a second protrusion 57 oppositely arranged on its edge. The second protrusion 57 has a through hole. The inner wall of the lower housing 51 has a slot 58 corresponding to the first protrusion 56. The battery compartment 5 has an opening 59 corresponding to the through hole on the second protrusion 57. During installation, the battery is placed into the battery compartment 5, then the first protrusion 56 is inserted into the slot 58. A bolt is passed through the through hole of the upper cover 52 and screwed into the opening 59 to secure the upper cover 52 securely to the lower housing 51. To form a sealed space, a sealing strip can be provided on the upper cover 52 or the lower housing 51. In this embodiment, a sealing strip is provided on the flange of the upper cover 52.

[0050] like Figures 4a-4cAs shown, in the third embodiment of this utility model, another circuit packaging structure for a replaceable battery is shown. The circuit packaging structure for a replaceable battery includes a circuit board 1, electrical connectors 21 and 22, a circuit board packaging cavity 3, an electrical connector fixing cavity 4, and a battery compartment 5.

[0051] The battery compartment 5 includes a detachably connected main cavity (only the bottom cover of the main cavity is shown in the figure, the top cover of the main cavity is not shown) and a side cover 6. The main cavity of the battery compartment 5 has a battery inlet / outlet on its side, and the side cover 6 can seal and fix itself to the battery inlet / outlet. As shown in the figure, the side cover is fixed to the main cavity of the battery compartment 5 by bolts. To form a sealed space, a sealing strip can be provided on the edge of the side cover 6 or on the battery inlet / outlet; in this embodiment, a sealing strip is provided on the edge of the side cover 6.

[0052] In addition, as shown in the figure, in this embodiment, the electrical connector fixing cavity 4 is located at the center of the middle position between the circuit board encapsulation cavity 3 and the battery compartment 5.

[0053] Other structures that are the same as those in the first embodiment will not be described in detail.

[0054] The embodiments of this utility model have been described above. However, this utility model is not limited to the above embodiments. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
