Description

Technical Field

[0001] The utility model relates to the technical field of storage batteries, in particular to a storage battery which is easy to assemble and disassemble. Background Art

[0002] A battery is a device that converts chemical energy directly into electrical energy. It's a rechargeable battery designed to be recharged, typically through a reversible chemical reaction. It's considered a secondary battery. The working principle of a battery is that during charging, it uses external electrical energy to regenerate internal active substances, storing the electrical energy as chemical energy. When discharged, the chemical energy is converted back into electrical energy for output. Therefore, batteries generally have charging and discharging terminals.

[0003] Batteries are currently widely used in electric vehicles, electronic products, aircraft, and other fields. Unmanned aerial vehicles (UAVs) are particularly popular. Due to their advantages such as aerial flight, high speed, and powerful payload capacity, UAVs have begun to make a name for themselves in various industries, revolutionizing them. They are now widely used in a variety of fields, including infrastructure planning, line inspection, emergency response, topographic surveying, and rail transit train inspection. After a UAV is operating, the charge level in its internal battery decreases. Therefore, the battery needs to be returned to the battery compartment for charging. After charging, the battery is then installed on the UAV to discharge the charge and provide power. Existing batteries have both charging and discharge terminals on the same side of the battery housing. This results in a problem: after fully charging the battery in the compartment, the battery needs to be removed from the compartment and repositioned before the discharge terminal can be inserted into the UAV to provide power. This results in inconvenience, cumbersome assembly and disassembly, slow connection speeds, and the risk of misconnection.

[0004] Therefore, there is an urgent need in the art for a battery that is simple to operate and can be quickly installed and disassembled. Utility Model Content

DETAILED DESCRIPTION

[0026] The present invention will be further described below with reference to the accompanying drawings:

[0027] like Figures 1 to 6As shown, the battery provided in the present invention, which is easy to assemble and disassemble, includes a battery cell 1 and a battery housing 2. The battery housing 2 is rectangular in shape, with a discharge contact 3 provided on one side of the battery housing 2 and a charging contact 4 provided on the other side of the battery housing 2 opposite the discharge contact 3. The discharge contact 3 and the charging contact 4 are positioned opposite each other, and the charging contact 4 and the discharge contact 3 are located along the length of the battery housing 2. The battery cell 1 is fixed within the battery housing 2. At the end of the battery housing 2 where the discharge contact 3 is located, one end of the battery cell 1 is connected to a discharge PCB 5. The discharge PCB 5 is provided with a discharge signal contact 6. The discharge signal contact 6 is connected to a sensor at the discharge end for detecting parameters such as the battery's discharge temperature and pressure. The discharge PCB 5 is connected to the discharge contact 3. At the end of the battery housing 2 where the charging contacts 4 are located, the other end of the battery cell 1 is connected to the charging PCB board 7. The charging PCB board 7 is provided with a charging signal contact 8 and a balancing charge contact (not shown). The charging signal contact 8 is connected to the sensor at the charging end to detect the charging temperature, pressure and other parameters of the battery. The balancing charge contact is used to monitor and adjust the voltage of each battery cell inside the battery in real time to prevent the occurrence of voltage imbalance. The charging signal contact 8 is supported and clamped by the contact blocking plate 9, making the battery structure more stable. The charging PCB board 7 is connected to the charging contact 4. A battery housing buckle cover 10 is provided at the end where the discharge contacts 3 of the battery housing 2 are located. The battery housing buckle cover 10 is provided with a snap-fit ​​portion 11 on both sides, so that the battery housing buckle cover 10 is snap-fitted to the battery housing 2 and closes the battery housing 2 to protect the components inside the battery housing 2. The battery case cover 10 has first square grooves 12 on either side of its upper end. The discharge contacts 3 are accommodated within these first grooves 12. A second circular groove 13 is provided in the middle of the upper end of the battery case cover 10. The signal contacts 3 are accommodated within these second grooves 13. A housing groove 14 is provided on the sidewall of the end of the battery case 2 where the charging contacts 4 are located. This makes the battery case 2 more compact. A transverse telescopic mechanism is provided in the width direction of the battery housing 2, and convex edges 15 are provided on both sides of the top of the battery housing 2 along the length direction of the battery housing 2. Through the convex edges 15 and the contraction of the transverse telescopic mechanism, the battery moves along the length direction and is mounted at the installation position through the battery mounting mechanism (not shown). At this time, the discharge contact 3 is electrically connected to the outside, and the battery discharges, that is, provides electrical energy to external electrical devices. Similarly, through the convex edge 15 and the contraction of the transverse telescopic mechanism, the battery moves along the length direction to the battery compartment, the charging contact 4 is connected to the battery compartment, and the battery is charged and stores electrical energy.

[0028] Specifically, when discharging the battery, the transverse telescopic mechanism is retracted with the aid of an external force, the lock is released, and the battery is moved along the convex edge 15, so that the discharge contacts 3 of the battery are connected to the external electrical device to achieve the discharge of the battery. When charging the battery, the transverse telescopic mechanism is also retracted with the aid of an external force, the lock is released, and the battery is moved along the convex edge 15, so that the charging contacts 4 of the battery are connected to the battery compartment to achieve the charging of the battery. By arranging the charging contacts and the discharge contacts 3 on both sides of the battery housing 2, there is no need to change the position when switching between charging and discharging the battery. The battery can be moved along the convex edge 15 to the installation position, achieving the effects of convenient assembly and disassembly and simple operation, and improving the convenience and accuracy of battery installation and disassembly.

[0029] It should be noted that the top of the battery housing 2 is not limited to the convex edge 15 arranged laterally along the length direction, and a groove (not shown) can also be provided. When the groove is arranged laterally along the length direction of the top of the battery housing 2, the mounting portion of the battery mounting mechanism matches the groove, so that the battery mounting mechanism can hang the battery and make the battery slide on the battery mounting mechanism.

[0030] It should be noted that the ridge 15 or groove is not limited to being set at the top of the battery housing 2, but can also be set on the two sides of the length direction of the battery housing 2. The mounting portion on the battery mounting mechanism matches the position of the ridge 15 or groove, and can hang the battery and allow the battery to slide on the battery mounting mechanism.

[0031] In this embodiment, the lateral telescopic mechanism is an elastic ear plate 17 with a protruding edge 15 vertically divided from the two side walls of the battery housing 2. The top and two sides of the elastic ear plate 17 are divided from the battery housing 2, while the bottom is connected to the battery housing 2. An elastic steel sheet 18 is provided in the elastic ear plate 17. The elastic steel sheet 18 includes a connected fixed portion 19 and a moving portion 20. The fixed portion 19 is inserted into the lower portion of the elastic ear plate 17, and the moving portion 20 is connected to the upper portion of the elastic ear plate 17. Due to the outward protrusion of the moving portion 20 of the elastic steel sheet 18 in a natural state, the elastic ear plate 17 protrudes from the side wall of the battery housing 2 in a natural state, thereby locking the battery in the installation position. When the elastic steel sheet 18 is subjected to force, the elastic ear plate 17 will shrink along with the moving portion 20, and shrink to a position basically flush with the battery housing 2 to release the lock.

[0032] In another preferred embodiment, the transverse telescopic mechanism is an elastic protrusion 16, such as Figure 7As shown, elastic protrusions 16 are provided on both sides of the battery housing 2 having the convex edge 15. The elastic protrusions 16 are linked to a linkage protrusion 23. When the linkage protrusion 23 is retracted by an external force, the elastic protrusions 16 follow the retraction of the linkage protrusion 23. When the linkage protrusion 23 is extended, the elastic protrusions 16 follow the extension of the linkage protrusion 23. When the elastic protrusions 16 are extended, the battery is locked in the installed position. When the elastic protrusions 16 are retracted, the battery is unlocked.

[0033] It should be noted that, in this preferred embodiment, the transverse telescopic mechanism is not limited to the elastic protrusion 16, but may also be an elastic groove. When the elastic groove is extended, the battery is locked in the installation position, and when the elastic groove is retracted, the battery is unlocked.

[0034] In this embodiment, the outer wall of the elastic lug 17 is provided with a plurality of protrusions 21. The protrusions 21 increase the friction on the outer surface of the elastic lug 17 when the elastic lug 17 is contracted by an external force, thereby strengthening the clamping force and preventing the elastic lug 17 from slipping. It should be noted that the protrusions 21 are not limited to being located on the outer wall of the elastic lug 17; they can also be located on the side wall of the battery housing 2. The outer wall of the elastic lug 17 is not limited to having a plurality of protrusions 21; it can also be provided with a plurality of recesses.

[0035] In this embodiment, the horizontal plane height of the end where the charging contact 4 is located is inconsistent with the horizontal plane height of the end where the discharge contact 3 is located, making it easier to distinguish the charging end and the discharge end, avoiding the risk of wrong connection.

[0036] In this embodiment, the battery housing 2 is further provided with line accommodating portions 22 on both sides in the longitudinal direction. The line accommodating portions 22 are used to accommodate the battery circuits, making the battery housing 2 more beautiful and avoiding the risk of fire caused by exposed battery circuits.

[0037] It should be noted that the battery in the present invention that is easy to disassemble and assemble is not limited to drones, but can also be used in other electrical devices such as electric vehicles and electronic products.

[0038] This embodiment is only an illustration of the concept and implementation of the utility model, and does not limit it. Under the concept of the utility model, technical solutions that have not been substantially changed are still within the scope of protection.
