Description

Technical Field

[0001] This utility model belongs to the field of lighting technology, specifically relating to a quick-release battery module structure and a flashlight containing the quick-release battery module structure. Background Technology

[0002] To facilitate use and achieve longer battery life, Chinese utility model patent CN202023029190X discloses a charging device for flashlights. This device, by incorporating a rechargeable battery compartment, a flashlight storage compartment, and charging / discharging components within the box, enables timely charging of the flashlight, thus meeting the requirement for long battery life. However, this device cannot effectively protect the flashlight, inevitably leading to squeezing and accidental contact during use or carrying. To address this, Chinese utility model patent CN2020221379752 discloses a rechargeable portable lighting device storage box. By creating an inner cavity within the box and incorporating a magnetic charging device within that cavity, it achieves effective protection and stable, reliable charging of the flashlight. This eliminates the need for a separate charger, combining the storage box and magnetic charger into one unit, facilitating outdoor use and effectively preventing accidental contact and squeezing of the flashlight during transport.

[0003] However, both of these flashlight charging devices share the same drawbacks: they use a traditional battery compartment structure for battery installation, requiring the battery compartment cover to be unscrewed for replacement, which is not quick and does not allow for rapid battery removal and installation. Furthermore, the charging circuit is separate from the battery, making it impossible to charge the battery independently when disconnected. In reality, both of these flashlight charging devices require removal and a dedicated charging interface or charger, significantly reducing their versatility and ease of use. Utility Model Content

[0004] The purpose of this invention is to provide a quick-release structure for quickly assembling and disassembling battery modules. At the same time, it adopts a separately rechargeable battery module as a power source, thereby realizing quick power supply replacement and an independent power source that can be charged separately.

[0005] To achieve the above objectives, this utility model provides a quick-release structure for a battery module, which is characterized by including a battery module and a battery module assembly compartment. A limiting slot is provided on the front side of the battery module, and a locking component is provided on the battery module assembly compartment to cooperate with the limiting slot to lock or unlock the battery module.

[0006] Furthermore, the battery module assembly compartment is a horizontally open space, including a rear compartment wall and a front compartment wall arranged opposite each other, and a longitudinal bottom plate connecting the bottom ends of the rear compartment wall and the front compartment wall.

[0007] The locking assembly includes a wrench with one end hinged to the top end face of the front compartment wall. The hinged end of the wrench is provided with a wrench holder, which is used to slide into or out of the limiting slot when the wrench swings left and right parallel to the top end face of the front compartment wall, thereby locking or unlocking the battery module.

[0008] Furthermore, a groove is provided on the top end face of the front compartment wall, and a vertical pivot is provided on the hinge end of the wrench component, which is inserted into the insertion hole at the tail end of the groove.

[0009] A transverse groove is formed on the front compartment wall, and the transverse groove communicates with the insertion hole;

[0010] A pin passes through the transverse groove and is mounted on the rotating shaft to limit the vertical movement of the wrench, so that the wrench swings only within the groove.

[0011] Furthermore, the circumferential sidewall of the groove is provided with at least a locking groove, a left unlocking groove and a right unlocking groove located to the left and right of the locking groove;

[0012] The wrench has an axial channel extending from its free end to the hinge end. A helical return spring is installed in the axial channel, and a steel ball is inserted at the entrance of the axial channel. When the wrench swings left and right, the steel ball presses against the circumferential sidewall of the groove and, under the elastic force of the helical return spring, moves in and out of the locking groove, the left unlocking groove, or the right unlocking groove, thereby restricting the wrench to the locked or unlocked position, and thus achieving the locking or unlocking of the battery module.

[0013] Furthermore, the battery module and the rear compartment wall are in the same shape, and the rear compartment wall is composed of a central vertical surface and symmetrical side surfaces arranged on both sides of the vertical surface.

[0014] Furthermore, a TYPE-C charging port is provided at the rear end of the battery module.

[0015] Furthermore, a flashlight with the aforementioned quick-release battery module structure is provided, including a main body, with the battery module assembly compartment integrated with the main body and located at the rear end of the main body.

[0016] Furthermore, the bottom surface of the main body is equipped with guide rails for mounting.

[0017] Furthermore, a rear positioning surface matching the side straight surface is provided on each side of the rear end face of the battery module;

[0018] The front end of the battery module is provided with a front positioning surface on each side, which matches the limiting surface on both sides of the rear end of the front compartment wall.

[0019] The advantages of this utility model are: it can realize quick assembly and disassembly of the power supply, especially the ability to charge independently, and can be equipped with at least two power supply modules, which greatly improves the flexibility and convenience of use.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature; in the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0031] To achieve quick installation and removal of the power supply, and to provide a replaceable, independently charging power source, thereby improving flexibility and ease of operation, this embodiment provides a quick-release structure for a battery module, including... Figure 1 The battery module 1 and battery module assembly compartment 2 are shown. A limiting slot 3 is formed on the front side of the battery module 1. The battery module assembly compartment 2 is equipped with a locking component that cooperates with the limiting slot 3 to lock or unlock the battery module 1. Figure 1 Clearly visible, the battery module assembly compartment 2 is a horizontally open space, including a rear compartment wall 4 and a front compartment wall 5 arranged opposite each other, and a longitudinal base plate 6 connecting the bottom ends of the rear compartment wall 4 and the front compartment wall 5; while the locking component includes a wrench 7 with one end hinged to the top end face of the front compartment wall 5. The hinged end of the wrench 7 is provided with a wrench locking plate 8, which is used to slide into or out of the limiting slot 3 when the wrench 7 is parallel to the top end face of the front compartment wall 5 and swings left and right, thereby realizing the locking or unlocking of the battery module 1.

[0032] The specific implementation structure is as follows:

[0033] A [missing information] is set on the top end face of the front compartment wall 5 Figure 2 The groove 9 shown is the hinge end of the wrench part 7. Figure 2 A vertical pivot 10 (perpendicular to the wrench component 7) is provided at the right end, and this vertical pivot 10 is inserted into the insertion hole 11 at the tail end of the groove 9; while a... Figure 1The transverse groove 12 shown communicates with the insertion hole 11; a pin 13 passes through the transverse groove 12 and is mounted on the rotating shaft 10 to limit the vertical movement of the wrench 7, so that the wrench 7 only swings within the groove 9; the bottom surface of the wrench holder 8 is fitted with the top surface of the groove 9 with a clearance fit, mainly because its height must match the limiting slot 3 on the battery module 1, so that the wrench holder 8 can be inserted into the limiting slot 3. Under this premise, the specific value of the clearance between the bottom surface of the wrench holder 8 and the top surface of the groove 9 can be set according to the design requirements.

[0034] At least one of the following is provided on the circumferential sidewall of the groove 9: Figure 1 The locking groove 14 shown, and the left unlocking groove 15 and right unlocking groove 16 located to the left and right of the locking groove 14, respectively, so that when the free end of the wrench 7 is located in Figure 1 or Figure 2 The right end of the wrench 7 is located within the locking groove 14, and the wrench holder 8 is inserted into the limiting groove 3, preventing the battery module 1 from being pulled out. When the free end of the wrench 7 is located within the left unlocking groove 15 or the right unlocking groove 16, the wrench holder 8 is located outside the limiting groove 3, releasing the restriction on the battery module 1, allowing the battery module 1 to be manually pulled out. This is much more convenient than the traditional threaded connection of the battery cover.

[0035] To accommodate the aforementioned switching between different positions, this embodiment... Figure 2 The wrench 7 shown has an axial channel 17 extending from its free end to the hinge end. A helical return spring 18 is installed in the axial channel 17. A steel ball 19 is inserted at the entrance of the axial channel 17. When the wrench 7 swings left and right, the steel ball 19 presses against the circumferential side wall of the groove 9 and, under the elastic force of the helical return spring 18, moves in and out of the locking groove 14, the left unlocking groove 15, or the right unlocking groove 16 (i.e., switching between different positions to lock or unlock the power module 1). This restricts the wrench 7 to the locked or unlocked position, thereby achieving the locking or unlocking of the battery module 1.

[0036] Depend on Figure 2 As can be seen, the battery module 1 and the rear compartment wall 4 have matching shapes. The rear compartment wall 4 is composed of a central vertical surface 20 and symmetrically arranged side surfaces 21 on both sides of the vertical surface 20, and the included angle between the vertical surface 20 and the side surfaces 21 is greater than 90° and less than 180°. Furthermore, in order to improve the stability of the mounting, the rear end face of the battery module 1 provided in this embodiment is provided with a rear positioning surface 26 on each side that matches the side surface 21; at the same time, a front positioning surface 27 is provided on each side of the front end face of the battery module 1 that matches the limiting surfaces 28 on both sides of the rear end of the front compartment wall 5. The lateral positioning of the battery module 1 is achieved through the matching side surfaces 21 and rear positioning surfaces 26, and the matching front positioning surfaces 27 and limiting surfaces 28.

[0037] Of course, the tail end of battery module 1 is equipped with Figure 3 The TYPE-C charging port 22 shown is compatible with current charging technology and improves charging convenience.

[0038] Finally, this embodiment provides a Figure 4 The flashlight shown, incorporating the quick-release battery module structure of the aforementioned embodiment, includes a main body 24.
