Detailed Implementation

[0030] The core of this application is to provide a connection structure for the battery and the extender to improve the reliability of the connection between the extender and the battery.

[0031] Another key aspect of this application is to provide a power supply device having the aforementioned connection structure for the battery and extender.

[0032] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0033] Power supply equipment generally includes a battery and an extender connected to the battery. Traditionally, the connection between the battery and the extender is achieved by the insertion and extraction force of the terminals. That is, the battery has female terminals and the extender has male terminals. The connection between the battery and the extender is achieved by inserting the male terminal of the extender into the female terminal of the battery.

[0034] However, due to the limited insertion and extraction force of the terminals, the extender and battery are prone to loosening after repeated insertion and extraction, causing the male terminal of the extender to separate from the female terminal of the battery, resulting in a loose connection or even a disconnection between the extender and the battery.

[0035] Therefore, such as Figures 1 to 3 As shown in the figure, this application discloses a connection structure for a battery 100 and an extender 200, including a first connection component and a second connection component. Based on ensuring the connection between the battery 100 and the extender 200 using the insertion and extraction force of the terminals, a claw 202 provided on the extender 200 extends into a slot 102 provided on the battery 100 to lock the extender 200 and the battery 100 together. This prevents the extender 200 and the battery 100 from becoming loose after repeated insertion and extraction, thus improving the reliability of the connection between the extender 200 and the battery 100.

[0036] The following will combine Figures 1 to 3 The connection structure for the battery 100 and the extender 200 disclosed in the embodiments of this application will be explained and described in detail.

[0037] Among them, such as Figure 1 and Figure 2As shown, the first connection component includes a first terminal 101 disposed on the battery 100 and a second terminal 201 disposed on the extender 200. The second terminal 201 is inserted into the first terminal 101 to realize the electrical connection between the extender 200 and the battery 100. At the same time, the insertion and extraction force of the terminal ensures the connection between the battery 100 and the extender 200. Specifically, the battery 100 includes a connection end 103, and a first notch is provided on the connection end face of the battery 100. The first notch has an L-shaped structure, the connection end 103 is located in the first notch, and the first terminal 101 is a female terminal disposed on the connection end 103. Meanwhile, the extender 200 includes a socket 203 for inserting into the connection end 103, and a second notch matching the first notch on the connection end surface of the battery 100 is provided on the connection end surface of the extender 200. The second notch has an L-shaped structure, the socket 203 is located in the second notch, and the second terminal 201 is a male terminal provided in the socket 203, so that when the battery 100 is connected to the extender 200, the outer surface of the battery 100 is flush with the outer surface of the extender 200, thereby ensuring the compatibility and stability of the battery 100 and the extender 200.

[0038] To prevent the extender 200 and battery 100 from becoming loose after repeated plugging and unplugging, such as Figure 1 and Figure 2 As shown, the second connection component includes a slot 102 disposed on the battery 100 and a claw 202 disposed on the extender 200 and cooperating with the slot 102. The claw 202 extends into the slot 102 to lock the battery 100 and the extender 200, thereby effectively preventing the extender 200 and the battery 100 from becoming loose after multiple insertions and removals, and improving the reliability of the connection between the extender 200 and the battery 100.

[0039] Furthermore, such as Figure 1 and Figure 2 As shown, a slot 102 is provided on at least one side of the connection end 103 of the battery 100, and a claw 202 is movably provided on at least one side of the socket 203 of the extender 200. By opening the slot 102 on one side of the connection end 103 of the battery 100 and setting the claw 202 on the socket 203 of the extender 200, the flatness of the outer surfaces of the battery 100 and the extender 200 can be avoided, thereby ensuring the reliability of the connection between the battery 100 and the extender 200 without increasing the external size of the power supply device.

[0040] In one specific embodiment, the claw 202 can be made of elastic rubber. When the connection end 103 of the battery 100 is inserted into the socket 203 of the extender 200, the connection end 103 of the battery 100 contacts the claw 202. As the connection end 103 of the battery 100 continues to be inserted, the claw 202 undergoes elastic deformation until the connection end 103 of the battery 100 is pressed against the bottom wall of the socket 203 of the extender 200. The claw 202 then moves to the position of the slot 102 of the connection end 103. At this point, the claw 202 returns to its original shape, allowing the claw 202 to extend into the slot 102, thereby locking the battery 100 and the extender 200. Similarly, when the connection end 103 of the battery 100 is separated from the socket 203 of the extender 200, simply pull the battery 100 or the extender 200 forcefully to overcome the elastic force of the claw 202 itself, and the connection end 103 of the battery 100 will be separated from the socket 203 of the extender 200.

[0041] To improve the ease of connection between the battery 100 and the extender 200, in one specific embodiment, such as Figure 4 As shown, the locking claw 202 includes a hook 2021 and a first reset elastic member 2022 disposed opposite to the hook 2021. When the connection end 103 of the battery 100 is inserted into the socket 203 of the extender 200, the connection end 103 of the battery 100 contacts the hook 2021 of the locking claw 202. As the connection end 103 of the battery 100 continues to be inserted, the first reset elastic member 2022 disposed opposite to the hook 2021 undergoes compression deformation until the connection end 103 of the battery 100 is pressed against the bottom wall of the socket 203 of the extender 200. The locking claw 202 just moves to the position of the slot 102 of the connection end 103. At this time, the first reset elastic member 2022 returns to its original deformation, so that the locking claw 202 extends into the slot 102, thereby locking the battery 100 and the extender 200. Specifically, an installation groove 204 is provided on at least one side of the socket 203 of the extender 200, and one end of the first reset elastic member 2022 is connected to the claw 202, and the other end of the first reset elastic member 2022 is connected to the bottom of the groove 204, so that when the connection end 103 of the battery 100 is inserted into the socket 203 of the extender 200, the hook 2021 can be locked under the action of the first reset elastic member 2022.

[0042] To facilitate the insertion of the battery 100 and the extender 200, a guide surface is provided on the hook 2021 to facilitate insertion into the slot 102. This guides the insertion of the connection end 103 of the battery 100 into the socket 203 of the extender 200. When the connection end 103 of the battery 100 contacts the claw 202, the hook 2021 of the claw 202 can be inserted into the slot 102 more quickly, thereby improving the convenience of the connection between the battery 100 and the extender 200.

[0043] To facilitate the separation of the battery 100 from the extender 200, in one specific embodiment, such as Figure 4 As shown, for ease of understanding, the two ends of the claw 202 are defined as the first end and the second end, respectively. The claw 202 is arranged parallel to the side wall of the socket 203 of the expander 200, and the second end of the claw 202 extends out of the side wall of the socket 203 of the expander 200, so that the second end of the claw 202 is in a cantilever state, and the second end of the claw 202 and the side wall of the socket 203 of the expander 200 form a fulcrum for the rotation of the claw 202. A first reset elastic element 2022 is disposed at the first end of the claw 202, and a push rod 2023 is disposed at the second end of the claw 202, so that the second end of the claw 202 can be pushed by the push rod 2023, allowing the claw 202 to rotate around the fulcrum. A second reset elastic element 2024 is sleeved on the push rod 2023, and the socket 203 of the expander 200 has a through cavity 205 on at least one side to facilitate the movement of the push rod 2023. In the initial state, the claw 202 is in contact with the side wall of the socket 203 of the extender 200, and the hook 2021 of the claw 202 is located in the slot 102, with the battery 100 and the extender 200 locked. When the battery 100 is separated from the extender 200, the push rod 2023 is pushed to move within the through cavity 205 until it abuts against the second end of the claw 202. At this time, the second reset elastic member 2024 is compressed and deformed, and the claw 202 rotates around the fulcrum. The first reset elastic member 2022 connected to the first end of the claw 202 is compressed and deformed, and the hook 2021 of the claw 202 disengages from the slot 102. At this time, the battery 100 and the extender 200 can be easily separated. When the battery 100 is separated from the extender 200, the push rod 2023 returns to its initial state under the elastic force of the second reset elastic member 2024, and at the same time, the hook 2021 of the pawl 202 returns to its initial position under the elastic force of the first reset elastic member 2022.

[0044] To facilitate the actuation of the push rod 2023, in one specific embodiment, such as Figure 4As shown, the through cavity 205 extends to one side of the expander 200, and the push rod 2023 is provided with a push plate 2025 for easy operation. One end of the second reset elastic member 2024 can be connected to the push plate 2025, and the other end of the second reset elastic member 2024 can be connected to the side wall of the socket 203. A groove for placing the push plate 2025 is provided on one side of the expander 200, and the groove communicates with the through cavity to ensure the aesthetics of the expander 200 after it is connected to the battery 100. When separating the battery 100 from the expander 200, simply pressing the push plate 2025 will push the push rod 2023 to move within the through cavity 205 and abut against the second end of the claw 202, thereby achieving quick unlocking between the battery 100 and the expander 200. It should be noted that an unlocking mark is also provided on the push plate 2025 so that the user can quickly find the unlocking position and achieve quick separation between the battery 100 and the expander 200.

[0045] Of course, a single reset spring element can be used to achieve quick locking and unlocking between the battery 100 and the extender 200.

[0046] In one specific embodiment, at least one side of the connector 203 of the extender 200 is provided with a telescopic cavity. A claw 202 is disposed perpendicular to the side wall of the connector 203 of the extender 200, and the second end of the claw 202 extends into the telescopic cavity. Simultaneously, the second end of the claw 202 is provided with a third reset elastic element, allowing the claw 202 to retract into the telescopic cavity by overcoming the elastic force of the third reset elastic element, thereby facilitating the separation and insertion of the battery 100 and the extender 200. When the battery 100 is inserted into the extender 200, the hook 2021 at the first end of the claw 202, under the elastic force of the third reset elastic element, inserts into the slot 102 to achieve locking between the battery 100 and the extender 200.

[0047] To facilitate the retraction of the claw 202 into the telescopic cavity, thereby separating the battery 100 from the extender 200, a pull rod extending out of the telescopic cavity is provided at the second end of the claw 202. This pull rod pulls the claw 202 to overcome the elastic force of the third reset elastic element and retract it into the telescopic cavity. Specifically, the telescopic cavity extends to one side of the extender 200, and the pull rod is equipped with a pull ring for easy operation. A groove for holding the pull ring is provided on one side of the extender 200. When the battery 100 and the extender 200 are in the plugged-in state, the hook 2021 at the first end of the claw 202 extends out of the telescopic cavity and into the slot 102 of the battery 100. At this time, the pull ring is located in the groove on one side of the extender 200. When it is necessary to separate the battery 100 from the extender 200, simply pull the pull ring. At this time, the pull ring will drive the claw 202 to retract into the telescopic cavity through the pull rod, overcoming the elastic force of the third reset elastic element, and thus separating the battery 100 from the extender 200.

[0048] In the above embodiments, the first reset elastic element, the second reset elastic element, and the third reset elastic element can be compression springs, thereby enabling the battery 100 to be quickly separated and connected to the extender 200 through the compression springs, and ensuring the reliability of the connection between the battery 100 and the extender 200.

[0049] To further improve the reliability of the connection between the battery 100 and the extender 200, in the above embodiment, two slots 102 can be used, and the two slots 102 are symmetrically arranged on both sides of the connection end 103. Meanwhile, as... Figure 4 As shown, two claws 202 can be used, and the two claws 202 are symmetrically arranged on both sides of the socket 203 so that the two claws 202 can extend into the corresponding slots 102, thereby making the connection between the battery 100 and the extender 200 more stable and improving the reliability of the connection between the battery 100 and the extender 200.

The battery 100 and the extender 200 are connected by a connection structure.
