DETAILED DESCRIPTION

[0020] The present invention will be described in further detail below with reference to the accompanying drawings.

[0021] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0022] An embodiment of the present invention: Figure 1 and Figure 2 As shown, a battery charger includes a shell 15, a battery compartment 2 and a rotatable compartment cover 3; an interface 7 is provided on one side of the shell 15, a circuit board 14 is provided in the shell 15, and the circuit board 14 is connected to the interface 7 through a wire; the battery compartment 2 is arranged above the shell 15, a second conductive spring 4 is provided on one side of the battery compartment 2, and the second conductive spring 4 is connected to the interface 7; the compartment cover 3 is arranged on the battery compartment 2, a first conductive spring 1 is provided on the side of the compartment cover 3 opposite to the second conductive spring 4, and the first conductive spring 1 is connected to the circuit board 14; one end of the compartment cover 3 is a hinged end, which is hinged to the shell 15 by a rotating shaft 16, and the battery compartment 2 can be rotated to open or close with the rotating shaft 16 as the axis, and the other end of the compartment cover 3 has a locking member, which can lock the closed compartment cover 3. When in use, as shown in FIG. Figure 3 As shown, the cover 3 is rotated to open, and the battery is placed in the battery compartment 2. The cover 3 is then closed. The first conductive spring 1 in the cover 3 presses against one side of the battery, and the other side of the battery presses against the second conductive spring 4, so that both sides of the battery contact the conductive springs. Finally, the cover 3 is locked by the locking member. The locking member locks the cover in the closed state to prevent the cover 3 from being accidentally opened. During charging, the battery can be locked in the charger to prevent it from loosening and avoiding touching the battery during charging, thereby improving safety. The cover 3 can be quickly opened and closed by a push button, allowing users to quickly replace batteries, which is convenient to operate.

[0023] In other specific embodiments of the present invention, the rest are the same as the above embodiments, except that, Figure 2 and Figure 3As shown, the locking member comprises a push button 5 and a spring 6. The push button 5 is slidably mounted in the upper opening of the housing 2. The compartment cover 3 is provided with a locking slot 18. One end of the spring 6 is connected to the lower portion of the push button 5, and the other end is connected to the interior of the housing 15. The push button 5 is retained in the locking slot 18 by the elastic force of the spring 6, locking the compartment cover 3. Pushing the push button 5 backward overcomes the elastic force and leaves the locking slot 18, releasing the compartment cover 3. The compartment cover 3 can now be rotated open to insert the battery. Closing the compartment cover 3 and then releasing the push button 5 causes the push button 5 to return to its original position under the elastic force, automatically returning to the locking slot 18 and locking the compartment cover 3.

[0024] In other specific embodiments of the present invention, the rest are the same as the above embodiments, except that, Figure 2 As shown, the push button 5 has anti-slip grooves on its surface, which makes it easier to apply pressure when held with one hand, thus making it more ergonomically designed.

[0025] In other specific embodiments of the present invention, the rest are the same as the above embodiments, except that, Figure 2 As shown, a rotating ring 8 is provided on one side of the bottom of the housing 15, and the outer circumference of the rotating ring 8 is covered with teeth 9. The housing 15 is provided with a knob 12. The lower part of the knob 12 is connected to a transverse limit shaft 10 via a longitudinal connecting rod 11. The limit shaft 10 has a pointed end. Turning the knob 12 drives the limit shaft 10 to move laterally, causing the limit shaft 10 to engage or disengage with the teeth 9. When the rotating ring 8 is rotated, it can be used for entertainment. When the rotating ring 8 is locked, it can be used to hang a charger. The mode of the rotating ring 8 is switched by turning the knob 2.

[0026] In other specific embodiments of the present invention, the rest are the same as the above embodiments, except that, Figure 1 As shown, the outer surface of the housing 15 is provided with a raised lock catch 19. Turning the knob 12 causes the limit shaft 10 to engage with the tooth groove 9. The knob 12 is then blocked below the lock catch 19, locking the swivel 8 and preventing rotation. Turning the knob 12 until it is blocked above the lock catch 19 disengages the limit shaft 10 from the tooth groove 9, unlocking the swivel 8.

[0027] In other specific embodiments of the present invention, the rest are the same as the above embodiments, except that, Figure 2 As shown, a guide groove 13 is provided in the housing 15, and one end of the limit shaft 10 is in the guide groove 13. The guide groove 13 is used to limit the movement stroke of the limit shaft 10 to prevent the limit shaft 10 from deviating.

[0028] In other specific embodiments of the present invention, the rest are the same as the above embodiments, except that, Figure 4As shown, an indicator light 20 is provided on the housing 15 and is electrically connected to the internal circuit board 14. The indicator light 20 can be used to display the charging progress of the battery to remind personnel to replace the rechargeable battery in time.

[0029] In other specific embodiments of the present invention, the rest are the same as the above embodiments, except that, Figure 1 As shown, the compartment cover 3 is made of transparent material, so the condition of the batteries in the battery compartment 2 can be observed intuitively.

[0030] In other specific embodiments of the present invention, the rest are the same as the above embodiments, except that, Figure 1 As shown, there is an opening 17 on one side of the first conductive elastic sheet 1 on the compartment cover 3. Heat is generated during battery charging, and the opening 17 is conducive to ventilation and heat dissipation in the battery compartment.

[0031] In other specific embodiments of the present invention, the rest are the same as the above embodiments, except that, Figure 4 As shown, the interface 7 is a Type-C interface, which is convenient for plugging in an external power cord.

[0032] The above embodiments are intended only to illustrate the technical concepts and features of the present invention. Their purpose is to enable those familiar with the art to understand the present invention and implement it accordingly. They are not intended to limit the scope of protection of the present invention. Any equivalent changes or modifications based on the spirit of the main technical solution of the present invention are intended to be covered by the scope of protection of the present invention.
