Description

Technical Field

[0001] This utility model relates to a quick-release structure for replacing batteries in handheld devices, belonging to the field of battery replacement technology. Background Technology

[0002] Handheld devices, such as handheld observation devices and handheld infrared devices, typically require independent battery power to function properly. These batteries are usually housed in a specially designed battery compartment, which the user then closes to ensure it forms a complete battery unit before installing it into the handheld device to power it.

[0003] Because handheld devices are used very frequently outdoors, and outdoor charging facilities are often inconvenient, they are usually equipped with additional replaceable batteries to ensure that they can be used outdoors for extended periods. When the handheld device's battery is low, the user can open the battery compartment cover, remove the low-powered battery, and quickly replace it with a new one, thus continuing to use the handheld device and ensuring its normal outdoor use.

[0004] However, existing battery compartment designs vary. Some battery compartments use a flip-up design, with one end of the cover connected to the compartment body via a hinge, and the other end snapped into place with a clip. To ensure a secure fit, the clips are typically quite tight, making it inconvenient to open the cover when replacing the battery. Furthermore, some battery compartments use screws for locking, requiring a screwdriver to open and close, making battery replacement cumbersome and negatively impacting the user experience. Therefore, there is an urgent need for a quick-release structure for replaceable batteries in handheld devices. Summary of the Invention

[0005] This invention addresses the shortcomings of existing technologies by providing a quick-release structure for replaceable batteries in handheld devices.

[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A quick-release structure for replacing batteries in handheld devices includes a battery compartment for accommodating batteries and a compartment cover assembly that cooperates with the battery compartment. The battery compartment is provided with a first locking hole and a second locking hole. The compartment cover assembly includes a battery compartment cover, a locking tongue, a rotating shaft, a first spring, and an operating wrench. The locking tongue includes a first locking tongue and a second locking tongue that are slidably disposed on the battery compartment cover. The first spring is disposed between the first locking tongue and the second locking tongue. Under the action of the first spring, the free end of the first locking tongue can extend out of the battery compartment cover and be inserted into the first locking hole, and the free end of the second locking tongue can extend out of the battery compartment cover and be inserted into the second locking hole. The rotating shaft is rotatably disposed on the battery compartment cover. One end of the rotating shaft can extend out of the battery compartment cover and be connected to the operating wrench. The other end of the rotating shaft is provided with a shaft head, and a rotating opening mechanism is provided between the shaft head and the locking tongue.

[0007] The beneficial effects of this utility model are: reliable locking and high security. Under the action of the first spring, the first and second locking tongues can be inserted and engaged with the first and second locking holes respectively, thereby locking the battery compartment and cover assembly closed. Without external force, the locking tongues can always maintain engagement with the locking holes, preventing accidental opening of the battery compartment cover. By driving the rotating shaft with an operating wrench, the locking tongues can be separated from the locking holes under the action of the rotating cover opening mechanism, allowing for quick opening of the cover assembly and replacement of the battery in the battery compartment without the need for other auxiliary tools, greatly improving the convenience of battery replacement. This utility model has a simple structure and convenient opening and closing operation, enabling easier and faster battery replacement, greatly improving the convenience of battery replacement in handheld devices and enhancing the user experience.

[0008] Based on the above technical solution, the present invention can be further improved as follows.

[0009] Furthermore, the rotating cover opening mechanism includes a first hook, a first actuating protrusion that can be engaged with the first hook, a second hook, and a second actuating protrusion that can be engaged with the second hook. The first hook is disposed on one side of the inner end of the first latch, the second hook is disposed on the other side of the inner end of the second latch, and the first actuating protrusion and the second actuating protrusion are respectively disposed on both sides of the shaft head.

[0010] The beneficial effect of adopting the above-mentioned further solution is that when the operating wrench is turned, the rotating shaft rotates accordingly. The first actuating protrusion on the shaft head actuates the first hook, and the second actuating protrusion actuates the second hook, causing the first and second locking tongues to retract inward against the elastic force of the first spring. The free end of the first locking tongue can disengage from the first locking hole, and the free end of the second locking tongue can disengage from the second locking hole, allowing the battery compartment cover assembly to open. This achieves the purpose of quickly removing and replacing the battery. After the replaced battery is placed into the battery compartment, the battery compartment cover assembly is closed. Turning the operating wrench to reset it causes the actuating protrusions to no longer act on the hooks. Under the action of the first spring, the locking tongues reset and engage with the locking hole to lock the battery compartment cover assembly and the battery compartment. Due to the presence of the first spring, the locking tongues can always remain protruding from the battery compartment cover and engage with the locking hole without external force. This rotating opening mechanism is ingeniously designed, easy to operate, and greatly improves the convenience of battery replacement.

[0011] Furthermore, the battery compartment is provided with a positioning groove for positioning the compartment cover assembly.

[0012] The advantage of adopting the above-mentioned further solution is that the positioning groove ensures that the cover assembly can be accurately aligned and installed on the battery compartment during installation, making the installation of the cover assembly convenient and quick.

[0013] Furthermore, a sealing ring is provided between the battery compartment and the compartment cover assembly.

[0014] The beneficial effects of adopting the above-mentioned further solution are that the sealing ring can further improve the sealing effect between the cover assembly and the battery compartment, ensure the dryness and cleanliness of the battery compartment, extend the battery's service life, and the sealing ring also plays a certain buffering role, reducing impact when the cover assembly is closed.

[0015] Furthermore, the battery compartment cover assembly also includes a decorative panel disposed on the inner side of the battery compartment cover, the decorative panel being able to protect the battery circuit board and position the battery circuit board on the battery compartment cover.

[0016] The beneficial effects of adopting the above-mentioned further solution are that, on the one hand, the decorative panel can meet the appearance requirements of the battery compartment cover assembly, and on the other hand, it can protect the battery circuit board from being scratched and rendered unusable by sharp objects, and can also be positioned on the battery compartment cover to meet the battery power supply requirements.

[0017] Furthermore, the battery compartment cover includes an outer cover and an inner cover. The outer cover and the inner cover are respectively provided with shaft holes for the shaft portion of the rotating shaft to pass through. A second spring is provided between the outer cover and the inner cover, and the locking tongue is slidably disposed on the inner cover.

[0018] The beneficial effect of adopting the above-mentioned further solution is that when the battery compartment cover is locked to the battery compartment, it ensures that the first locking tongue and the second locking tongue can smoothly enter the first and second locking holes, while providing operating space for the subsequent sealing action of the battery compartment cover.

[0019] Furthermore, a gasket is provided between the operating wrench and the outer cover of the compartment. The outer surface of the gasket is smooth, and one or more gasket grooves are provided on the inner surface. The outer cover of the compartment is provided with a groove for positioning the gasket.

[0020] The beneficial effects of adopting the above-mentioned further solution are that the smooth outer surface of the gasket can reduce the wear between the operating wrench and the outer cover of the compartment, thus protecting the outer cover of the compartment, and the groove of the gasket on the inner surface can reduce weight.

[0021] Furthermore, the rotating shaft is also provided with a retaining ring, and the rotating shaft is connected to the inner cover of the compartment through the shaft head and the retaining ring.

[0022] The beneficial effect of adopting the above-mentioned further solution is that the shaft head of the rotating shaft is located on one side of the inner cover, the shaft part of the rotating shaft passes through the shaft hole on the inner cover, and a retaining spring can be installed on the shaft part on the other side of the inner cover, so as to fix the rotating shaft to the inner cover.

[0023] Furthermore, the compartment cover assembly also includes a pressure plate, which is disposed on the inner compartment cover, and there is a movable space between the pressure plate and the inner compartment cover for the first locking tongue and the second locking tongue to slide.

[0024] The beneficial effect of adopting the above-mentioned further solution is that the pressure plate can not only enhance the structural strength of the cover assembly, but also provide sufficient space for the sliding of the locking tongue, ensuring the smooth operation of the quick-release structure.
