Description

Technical Field

[0001] This utility model belongs to the field of battery boxes, specifically relating to a portable rechargeable battery clip. Background Technology

[0002] Portable power devices such as angle grinders and electric drills have limited battery power, allowing them to operate only within their rated capacity. In certain usage environments, they cannot operate continuously for extended periods, thus disrupting work processes and reducing efficiency.

[0003] Generally, portable device manufacturers extend the battery life of their devices by increasing battery capacity or by pre-installing connectors inside the battery compartment for connecting to specific battery packs, facilitating battery pack replacement and thus increasing the device's runtime. However, some existing battery boxes or clips for installing battery packs use a row-style arrangement of batteries, which results in poor heat dissipation, inconvenience in battery removal and replacement, and a tendency for batteries to detach or become loosely connected under extreme vibration conditions. Utility Model Content

[0004] In view of the problems existing in the background technology, this utility model proposes a portable rechargeable battery clip, which allows portable power devices to quickly and conveniently add battery packs, extend battery life, and at the same time improve heat dissipation performance, ensure stable and reliable battery installation, and facilitate battery removal and replacement.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a portable rechargeable battery clip, including a battery shell, with an upper concave platform and a lower concave platform respectively provided at both ends of the battery shell, an upper electrode plate and a battery clip cover being installed sequentially on the upper concave platform, and a lower electrode plate and a battery clip cover being installed sequentially on the lower concave platform, wherein the upper electrode plate and the lower electrode plate are electrically connected to the positive and negative terminals of the battery respectively.

[0006] The battery casing has a centrally symmetrical figure-eight structure, with a first cavity and a second cavity for carrying the battery, and a cavity in the middle that communicates with the first cavity and the second cavity. The cavity is provided with heat dissipation holes and communicates with the outside.

[0007] The first and second cavities have a notch on one side for removing the battery. The notch is semi-circular in structure, and an arc-shaped battery cover is hinged to the other side. The battery cover and the battery casing are magnetically attached to each other.

[0008] The upper electrode plate and the lower electrode plate each have a contact end and a bent spring piece, and the contact end and the spring piece can be electrically connected to the positive terminal and the negative terminal of the battery in the first cavity and the second cavity, respectively.

[0009] The outer side of the battery clip cover has a groove, and a button film is provided in the groove. The upper electrode plate has a positive copper pillar that can pass through the battery cover and contact the button film.

[0010] The button film has a transparent window for displaying the battery level.

[0011] The lower electrode plate has several negative copper pillars on its outer side, and the negative copper pillars can extend outward through the lower cover of the battery clip.

[0012] The beneficial effects of this utility model are:

[0013] Compared to existing technologies, the battery casing of this invention features a centrally symmetrical figure-eight structure. The internal cavity, prone to heat accumulation, connects to the outside through heat dissipation holes, allowing heat to escape and improving heat dissipation performance. Furthermore, the battery can be securely closed with a battery cover after installation, ensuring a more stable and reliable installation and preventing the battery from detaching under extreme vibration conditions. Semi-circular notches are also provided on one side of the first and second cavities for battery installation, further facilitating battery removal and replacement. Attached Figure Description

Detailed Implementation

[0022] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the preferred embodiments of this utility model will be described in detail below with reference to the accompanying drawings, so as to facilitate understanding by those skilled in the art.

[0023] Example 1

[0024] See Figures 1 to 6 A portable rechargeable battery clip includes a battery housing 1. The battery housing 1 has an upper recess 101 and a lower recess 102 at both ends. An upper electrode plate 2 and a battery clip cover 3 are sequentially installed on the upper recess 101. The upper electrode plate 2 is electrically connected to the positive electrode of the battery.

[0025] like Figure 3 and Figure 4 The upper electrode plate 2 shown has a contact end 203 on the side facing the bottom of the upper recess 101. The contact end 203 extends into the first cavity 103 and the second cavity 104 and is electrically connected to the positive electrode of the battery. The outer side of the battery clip cover 3 (i.e., the side facing away from the upper electrode plate 2) has a groove 301, and a button film 4 is installed inside the groove 301. On the side of the upper electrode plate 2 facing away from the bottom of the upper recess 101, a connector 201 and a positive copper pillar 202 are electrically connected in sequence. The connector 201 is a cuboid structure used to support the upper and lower covers to ensure the stability of their relative positions. The positive copper pillar 202 can pass through the battery cover and contact the button film 4. The button film 4 has a viewing window 401 for power display, and at the contact position with the positive copper pillar 202, facing away from the battery cover, the button film 4 has a protrusion 402 for connection to an external portable power device.

[0026] like Figure 1 and Figure 5 The recessed platform 102 shown is sequentially fitted with a lower electrode plate 5 and a battery clip cover 6. The lower electrode plate 5 is electrically connected to the negative terminal of the battery. The lower electrode plate 5 has a bent spring tab 501 on the side facing the bottom of the recessed platform 102. The spring tab 501 is made of elastic copper plate material and extends into the first cavity 103 and the second cavity 104, electrically connecting to the negative terminal of the battery. The elasticity of the spring tab 501 ensures the stability of the battery after it is installed in the first cavity 103 and the second cavity 104, guaranteeing an effective electrical connection between the spring tab 501 and the battery.

[0027] like Figure 1 and Figure 5 The lower electrode plate 5 shown has six negative copper pillars 502 on its outer side. The negative copper pillars 502 can extend outward through the lower cover 6 of the battery clip. Multiple negative copper pillars 502 can be easily connected to external portable electrical devices.

[0028] like Figure 1 and Figure 6 The battery casing 1 shown is a centrally symmetrical figure-eight structure. The two circular cavities of the figure-eight are the first cavity 103 and the second cavity 104 for carrying the battery. The middle part is also provided with a cavity 105 that communicates with the first cavity 103 and the second cavity 104. The cavity 105 is provided with heat dissipation holes 106 that communicate with the outside, so that the heat accumulated between the two batteries can be discharged in the heat dissipation holes 106 with the convection air.

[0029] like Figure 1 and Figure 6 The first cavity 103 and the second cavity 104 shown have a notch 108 on one side for removing the battery. The notch 108 has a semi-circular structure. In use, the battery can be pried out by contacting the side of the battery facing the bottom of the first cavity 103 or the second cavity 104 (the side closer to the cavity 105) through the notch 108, making it easier to remove the battery. An arc-shaped battery cover 7 is hinged to the other side of the first cavity 103 and the second cavity 104. The battery cover 7 is magnetically attached to the battery casing 1.

[0030] like Figure 1 and Figure 2 The battery casing 1 shown has a permanent magnet 107 on its edge, and the battery cover 7 has an iron piece 702 corresponding to the permanent magnet 107 on its edge. This allows the battery cover 7 to be tightly closed during battery closing, preventing the battery from falling out or shifting. Simultaneously, the battery cover 7 also has corresponding heat dissipation holes 106 to enhance airflow inside the first cavity 103 and the second cavity 104. Furthermore, a protrusion 701 is provided at the midpoint of the edge of the battery cover 7 to facilitate flipping the battery cover 7.

[0031] The battery casing 1 of this invention has a centrally symmetrical figure-eight shape. The internal cavity, which is prone to heat accumulation, is connected to the outside through heat dissipation holes 106, allowing heat to dissipate through these holes, resulting in better heat dissipation. Furthermore, the battery can be closed with the battery cover 7 after installation, making the battery installation more stable and secure, preventing it from falling off under extreme vibration conditions. A semi-circular notch 108 is also provided on one side of the first cavity 103 and the second cavity 104 used for battery installation, further facilitating battery removal and replacement.

[0032] Finally, it should be noted that although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes in form and detail can be made thereto without departing from the scope defined by the claims of the present invention.
