The first terminal and the second terminal are plugged into each other to realize the electrical connection between the elastic pin and the conductive plate.

[0011] Furthermore, a sealing element is provided at the connection between the first terminal and the second terminal.

[0012] Furthermore, a window communicating with the interior is provided on the side wall of the housing;

[0013] The battery compartment includes a rotating end and a free end. The rotating end is rotatably disposed inside the housing, and the free end swings around the rotating end, either swinging out through a window to unfold outside the housing or swinging in through a window to be stored inside the housing.

[0014] The battery compartment and the housing can be locked in place or unlocked and popped out by pressing a self-locking switch.

[0015] Furthermore, the battery compartment is rotatably mounted on the housing via a cover. One end of the cover is pivotally connected to the inside of the housing, and the other end swings around the pivot. The battery compartment is fixed to the cover. When the battery compartment is stored inside the housing, the cover is tightly fastened to the window of the housing, and the outer surface of the cover is flush with the outer surface of the housing.

[0016] Furthermore, the button pin is a deformable structure located on the cover. The button pin includes a fixed end and a pin end. The fixed end is fixedly connected to the cover, and the pin on the pin end extends through the pin hole in the side wall of the battery compartment to the surface of the battery.

[0017] Furthermore, the rear end of the elastic element is fixed to the inner wall of the battery compartment, and the front end of the elastic element abuts against the rear end of the battery.

[0018] Furthermore, the elastic element is a return spring, and two return springs are symmetrically arranged between the battery and the battery compartment.

[0019] After adopting the above solution, the beneficial effects of this utility model are as follows:

[0020] This utility model's pop-out self-locking battery box device achieves highly stable battery installation through a self-locking buckle structure. Furthermore, it establishes a one-button pop-out mechanism through the design of a button pin and elastic elements. Users can pop the battery out of the battery compartment by pressing this button, eliminating the need for manual removal. This not only makes operation convenient but also effectively avoids potential damage to the battery during removal, greatly improving the convenience and safety of battery replacement and maintenance.

[0021] The battery and the conductive plate on the battery compartment are connected by a flexible pin structure, which can effectively avoid poor contact caused by size differences.

[0022] In addition, the pop-out self-locking battery box device of this utility model has good moisture-proof performance.

[0042] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0043] This utility model provides a pop-out self-locking battery box device, such as... Figures 1 to 10 As shown, it includes a housing 1, a battery compartment 2, and a battery 6. The battery compartment 2 is detachably installed inside the housing 1.

[0044] The battery compartment 2 houses the battery and has a front opening 21 for the battery 6 to enter and exit. Regarding the connection between the battery compartment 2 and the housing 1, this invention is not limited to a specific form. The battery compartment 2 can slide in and out of the housing 1, or it can be pivotally connected to the housing 1, unfolding to the outside of the housing 1 or retracting into the housing 1 by rotation. The key is to ensure that the front opening 21 of the battery compartment 2 is exposed to the outside of the housing 1 when needed, facilitating the installation and removal of the battery 6. See below for details.

[0045] The key feature of this invention lies in the installation method of the battery 6 and the battery compartment 2. For example... Figure 1 , Figure 2 and Figure 5 As shown, the battery 6 is fixed to the battery compartment 2 by a self-locking latch structure 7. Specifically, the self-locking latch structure 7 includes a first latch 71 and a second latch 72. The first latch 71 is located at the front end inside the battery compartment 2, and the second latch 72 is located at the front end of the battery 6. When the battery 6 is inserted into the battery compartment 2, pressing the battery inward and downward causes the first latch 71 and the second latch 72 to engage, thereby fixing the battery 6 inside the battery compartment 2.

[0046] To enable quick and convenient unlocking of battery 6, this invention includes a button pin 8 structure at the bottom of the battery compartment 2. For example... Figure 1 and Figure 2As shown, the push pin on the button push pin 8 extends through the push pin hole 25 on the side wall of the battery compartment 2 toward the surface of the battery 6. When the self-locking latch structure 7 is in the self-locking state, the user can press the button push pin 8 to push the battery 6 upward, causing the second latch 72 on the battery 6 to disengage from the second latch 72 on the battery compartment 2, thereby unlocking the battery 6, which can then be removed from the battery compartment 2.

[0047] To enable the unlocked battery 6 to automatically eject from the battery compartment 2, an elastic element 9 is designed within the battery compartment 2. In one embodiment, as shown... Figure 2 As shown, the rear end of the elastic element 9 is fixed to the inner wall of the battery compartment 2, while the front end of the elastic element 9 remains free and is not fixed to any object. Only when the battery 6 is inserted into the battery compartment 2 does the rear end of the battery 6 abut against the front end of the elastic element 9, gradually compressing the elastic element 9 until the self-locking latch structure 7 is in the locked state, at which point the elastic element 9 is compressed into place. The compression process of the elastic element 9 is also a force-accumulating process, that is, providing the battery 6 with the elastic force to detach from the battery compartment 2 through the front opening 21. In this embodiment, we selected a return spring as the elastic element 9. Two return springs are symmetrically arranged inside the battery compartment 2, located on both sides of the battery 6, to ensure that the battery 6 can be smoothly and evenly subjected to the elastic force after unlocking, thereby achieving the effect of automatic ejection.

[0048] The electrical connection between battery 6 and battery compartment 2 is as follows: Figure 2 and Figure 1 As shown, a first terminal 61 is formed at the rear end of the battery 6. A resilient pin 62 is provided inside the first terminal 61. This resilient pin 62 is made of a material with good guiding properties, ensuring the accuracy and stability of the electrical contact. Correspondingly, a second terminal 23 is provided inside the battery compartment 2, and a conductive plate 24 is provided inside the second terminal 23. When the battery 6 is correctly inserted into the battery compartment 2, the first terminal 61 and the second terminal 23 will achieve precise insertion and engagement. At this time, the resilient pin 62 will make tight contact with the conductive plate 24, thereby establishing a stable electrical connection.

[0049] To further enhance the moisture-proof performance of this electrical connection and ensure stable electrical conductivity under various environments, a sealing element 10, such as a rubber sealing ring, is added at the connection between the first terminal 61 and the second terminal 23. (Refer to...) Figure 1 and Figure 5 The presence of these seals 10 effectively prevents the intrusion of harmful substances such as external moisture and dust, protecting key structures such as the elastic pin 62 and the conductive plate 24 from the damage caused by a humid environment, thereby extending the service life of the battery box and improving the overall reliability and safety.

[0050] In this embodiment, the battery compartment 2 and the housing 1 are rotatably connected, and the specific connection method is as follows: Figure 1 As shown, a window 11 is provided on the side wall of the housing 1, leading to its interior. The battery compartment 2 enters and exits the housing 1 through this window 11. A cover 3 is provided at the window 11, with one end of the cover 3 pivotally connected to the interior of the housing 1 and the other end swinging around the pivot. The cover 3 can swing outward from the interior of the housing 1 through the window 11, unfolding outside the housing 1, or swing inward from the exterior of the housing 1 through the window 11, retracting inside the housing 1. Here, when the cover 3 is retracted inside the housing 1, the cover 3 is tightly fastened to the window 11 of the housing 1, and the cover 3 and the housing 1 form an airtight seal, effectively improving the sealing and moisture-proof performance of the battery box housing 1, ensuring that the internal components are not affected by external environmental factors. Moreover, the outer surface of the cover 3 is flush with the outer surface of the housing 1, which not only further improves the sealing and moisture-proof performance of the battery box housing 1, but also improves the overall aesthetics of the battery box.

[0051] In this embodiment, the specific structure of the rotatable connection between the face cover 3 and the housing 1 is as follows: the housing 1 has rotating seats 12 on both sides of the window 11 inside, and correspondingly, the face cover 3 has rotating shafts 31 on both sides. The rotating shafts 31 are pivotally connected to the rotating seats 12, thereby realizing the smooth and stable rotation function of the face cover 3 relative to the housing 1.

[0052] like Figure 1 As shown, the battery compartment 2 is fixed to the cover 3 and rotates synchronously with the cover 3. When the cover 3 is unfolded outside the housing 1, one end of the front opening 21 of the battery compartment 2 is also exposed, allowing the battery to be removed from the battery compartment 2. When the cover 3 is retracted inside the housing 1, the battery compartment 2 is hidden, effectively enhancing the sealing of the battery compartment, preventing dust and moisture from entering, and protecting the battery safety.

[0053] In this embodiment, as Figure 1 and Figure 4 As shown, the button pin 8 is a deformable structure located on the cover 3. The button pin 8 includes a fixed end and a pin end. The fixed end is fixedly connected to the cover 3. The pin on the pin end extends through the pin hole 25 on the side wall of the battery compartment 2 to the surface of the battery 6 to lift the battery.

[0054] As a further improvement to the structure, such as Figure 1 and Figure 5As shown, a fixing seat 4 is also provided inside the housing 1. The fixing seat 4 is shaped to match the battery compartment 2, and its cross-section is U-shaped. The U-shaped fixing seat 4 is fixed to the window 11 with its lower opening 41 facing the window 11. The fixing seat 4 and the housing 1 form a receiving cavity for the battery compartment 2. Here, the side of the fixing seat 4 near the rotating end of the battery compartment 2 and adjacent to the lower opening 41 of the U-shaped fixing seat 4 has a side opening 42. This side opening 42 communicates with the lower opening 41, forming a spacious clearance space. This design ensures that when the cover 3 and the battery compartment 2 swing, whether they are unfolded from the inside of the housing 1 or retracted from the outside, they can move freely and smoothly in this clearance space without being obstructed.

[0055] This invention utilizes a press-locking switch 5 to achieve flexible switching between the battery compartment 2 being deployed outside the housing 1 and retracted and fixed inside the housing 1. The specific implementation method is as follows:

[0056] like Figure 1 and Figure 5 As shown, the top of the fixing base 4 protrudes from the inside out, forming a fixing chamber 43 for fixing the self-locking switch 5 by pressing. A card slot 431 is provided on the side wall of the fixing chamber 43, and correspondingly, as shown... Figure 8 As shown, the outer side of the bracket 51 of the self-locking switch 5 has a locking block 511 that mates with the card holder 431. When the locking block 511 of the bracket 51 is tightly engaged with the card holder 431 of the fixing chamber 43, the self-locking switch 5 is securely fixed in the fixing chamber 43.

[0057] like Figure 1 As shown, the free end of the battery compartment 2, facing the interior of the housing 1, is equipped with a hook 22. It should be noted that the battery compartment 2 is defined here as a structure with a rotating end and a free end. The rotating end is the end that rotates relative to the housing 1, while the free end is the end outside the rotating end that is not bound by the housing 1 and swings around the rotating end. Therefore, when the battery compartment 2 is unfolded outside the housing 1, the user only needs to apply an external force to the free end of the battery compartment 2 towards the interior of the housing 1, and the free end of the battery compartment 2 will swing inwards towards the housing 1. During this process, the hook 22 on the battery compartment 2 will gradually approach and trigger the self-locking switch 5. Once the hook 22 is captured and fixed by the self-locking switch 5, the battery compartment 2 achieves a retracted and locked state. When the battery compartment 2 is retracted inside the housing 1 and needs to be unfolded again, the user only needs to press the free end of the battery compartment 2 again to unlock the hook 22 and disengage it from the self-locking switch 5, at which point the battery compartment 2 can swing freely.

[0058] like Figure 3 and Figure 5As shown, when the cover 3 of the battery compartment 2 is stored and fixed inside the housing 1, the outer surface of the cover 3 remains flush with the outer surface of the housing 1. Therefore, when the latch 22 successfully disengages from the self-locking switch 5, the cover 3 is naturally exposed outside the housing 1, providing the user with intuitive visual feedback and ensuring that the user can easily identify and operate the opening of the battery compartment 2. This effectively avoids the embarrassing situation of being unable to open the battery compartment 2 due to structural problems. Furthermore, the self-locking switch 5 is not only used for locking, but its built-in spring mechanism also plays a crucial role. When the latch 22 is unlocked, the spring force provided by the self-locking switch 5 acts as an assist, pushing the free end of the battery compartment 2 slightly out of the housing 1, providing the user with the initial power to open the battery compartment 2.

[0059] The push-to-lock switch 5 is a commercially available switch, such as... Figure 8 As shown, the assembly includes a bracket 51, a slider 52, a swing rod 53, and an elastic element 54. The slider 52 is disposed within the bracket 51 and slides up and down along the bracket 51. The lower end of the slider 52 has a gripper 521, which closes or opens as the slider 52 slides up and down. The bracket 51 is provided with a guide rail 512, which is lightning-shaped with the left side higher than the right side. The upper end of the swing rod 53 slides along the guide rail 512 and engages with the slider 52, allowing it to swing left and right relative to the slider 52. The elastic element 54 abuts against the upper end of the slider 52 and the bracket 51.

[0060] When the user needs to lock battery compartment 2, refer to Figures 9 to 10 The process involves simply using the hook 22 to lift the slider 52 upwards, which compresses the elastic element 54 and drives the swing rod 53 to move upwards. The swing rod 53 moves upwards along the guide rail 512 and deflects to the left, engaging with the higher guide rail 512 on the left side, thereby fixing the slider 52. At this time, the claw 521 at the lower end of the slider 52 is squeezed inwards by the side wall of the bracket 51, thus clamping the hook 22, which locks the cover 3 and the battery compartment 2 onto the housing 1.

[0061] When a user needs to unlock battery compartment 2, refer to... Figures 10 to 9 The process involves simply using the hook 22 to push the slider 52 upwards again, causing the lever 53 to deflect to the right, disengaging from the higher left guide rail 512 and entering the lower right guide rail 512. At this point, the slider 52 moves downwards under the restoring force of the elastic element 54. As the slider 52 descends, the gripper 521 gradually unfolds until it completely disengages from the hook 22 of the battery compartment 2, unlocking the device and causing the cover 3 and battery compartment 2 to pop open.

[0062] The specific operation for removing and placing batteries in this pop-out self-locking battery box device is as follows:

[0063] Open the cover to remove the battery (reference) Figures 5-6 - Figure 7 ):

[0064] Press the cover 3 to automatically pop out and unfold the cover 3 and the battery compartment 2. Then press the button pin 8 to lift the battery 6. The battery 6 is ejected from the battery compartment 2 by the elastic element 9. At this time, the battery 6 can be manually removed and replaced.

[0065] Insert battery and close cover (for reference) Figures 7-6 - Figure 5 ):

[0066] Place the new battery 6 into the battery compartment 2, making sure to insert the end with the elastic pin 62 first so that it aligns with the conductive plate 24 of the battery compartment 2 to avoid ineffective installation; continue to push the battery 6 inward and downward until the first latch 71 and the second latch 72 engage; then push the cover 3 and the battery compartment 2 toward the housing 1 to lock the self-locking switch 5.
