Description

Technical Field

[0001] The utility model relates to the technical field of quick-release structures, in particular to a quick-release self-locking structure for modular batteries. Background Art

[0002] Existing modular batteries typically use elastic clips, movable baffles, bolts, pins, and other methods to limit or lock the assembly of electrical devices. These fixing methods have several drawbacks: elastic clips and movable baffles require high material strength, durability, and machining precision; bolt fixing requires additional tools and time during assembly and disassembly of the modular battery; and pin fixings experience significant wear and tear on parts, complex assembly and disassembly procedures, and the presence of small, independent parts within the entire assembly. These issues lead to problems such as short lifespan of the fixing structure, insufficient fixing precision, wobble due to improper locking, and time-consuming and labor-intensive assembly and disassembly when assembling modular batteries with electrical devices. Utility Model Content

[0003] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a quick-release self-locking structure for modular batteries, which is convenient for assembly and disassembly.

[0004] The technical solution of the present utility model is: a quick-release self-locking structure for a modular battery, comprising a base, a limit seat and a quick-release self-locking module, the limit seat being arranged in the base and forming an accommodating space, the quick-release self-locking module being arranged in the accommodating space, the quick-release self-locking module comprising a carrying handle and a buckle block and a hinge block arranged on both sides of the carrying handle, the carrying handle being connected to the limit seat through an elastic member, the middle portion of the buckle block being hinged to one end of the hinge block, the other end of the hinge block being hinged to the bottom of the carrying handle, the buckle block being rotatably connected to the limit seat, through grooves communicating with the accommodating space being provided on both sides of the limit seat, buckle grooves adapted to the buckle block being provided on both sides of the inner wall of the base, the buckle block passing through the through groove and being limited in the buckle groove to achieve locking.

[0005] As can be seen from the above solution, the hinge block is used to connect the handle and the snap block, and is used to convert the linear motion of the handle into rotational motion of the snap block through the hinge block, thereby locking the limit seat within the base. This utility model simplifies the steps for modular battery disassembly and assembly, shortens disassembly and assembly time, and can be completed without the need for additional tools or parts.

[0006] A first connecting block is provided in the middle of the bottom of the handle, a corresponding limiting groove is provided within the limiting seat, which is adapted to the elastic member. The limiting seat is provided with a second connecting block at the bottom of the limiting groove. The first connecting block and the second connecting block are arranged in a vertically corresponding manner. One end of the elastic member is connected to the first connecting block, and the other end is connected to the second connecting block. Thus, the limiting groove is used to limit the position of the elastic member, and the ends of the elastic member are connected to the handle and the limiting seat through the first and second connecting blocks.

[0007] The middle portion of the snap block is hinged to one end of the hinge block via a first short pin, the other end of the hinge block is hinged to the bottom of the handle via a second short pin, and the upper end of the snap block is rotatably connected to the limit seat via a long pin. Thus, the snap block is hinged to the handle via the hinge block, and the upper end of the snap block is rotatably connected to the limit seat via the long pin.

[0008] The locking block is wedge-shaped, with escape grooves on both sides of the handle bottom. The bottom wall of the position-limiting seat is provided with an arc-shaped escape portion corresponding to the locking block. The escape grooves allow the handle's sides to escape from the inside of the locking block when the locking block is locked, while the arc-shaped escape portion guides the locking block toward the bottom of the device when it rotates.

[0009] The elastic member is a tension spring, one end of which is hung on the first connecting block, and the other end of which is hung on the second connecting block.

[0010] The end of the handle is provided with a handle groove, which makes it easy to grasp the handle and pull it. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] like Figures 1 to 4As shown, the utility model is a quick-release self-locking structure for a modular battery, comprising a base 1, a limiting seat 2 and a quick-release self-locking module, the limiting seat 2 being arranged in the base 1 and forming an accommodating space, the quick-release self-locking module being arranged in the accommodating space, the quick-release self-locking module comprising a carrying handle 3 and a buckle block 4 and a hinge block 5 arranged on both sides of the carrying handle 3, the carrying handle 3 being connected to the limiting seat 2 through an elastic member 6, the middle part of the buckle block 4 being hinged to one end of the hinge block 5, and the other end of the hinge block 5 being hinged to the bottom of the carrying handle 3, the buckle block 4 being rotatably connected to the limiting seat 2, through grooves 21 communicating with the accommodating space being provided on both sides of the limiting seat 2, buckle grooves 11 adapted to the buckle block 4 being provided on both sides of the inner wall of the base 1, the buckle block 4 passing through the through groove 21 and being limited in the buckle groove 11 to achieve locking. In this embodiment, all components of the present invention, except for the base 1, are mounted within the retaining base 2. They appear to be a single unit and remain inseparable during use, though they experience relative internal movement. This unit is referred to as a modular battery unit. The base 1 is provided with a chute with one end open, which mates with the retaining base 2. The width of the chute's end opening is greater than the width of the handle 3, facilitating grasping and stretching the handle 3. The retaining groove 11 is a triangular recess.

[0017] The handle 3 is provided with a handle groove 30 at its end, and a first connecting block 31 is provided at the middle of its bottom. A corresponding limiting groove 22 is provided within the limiting seat 2, which is adapted to mate with the elastic member 6. A second connecting block 23 is provided at the bottom of the limiting groove 22 within the limiting seat 2. The first connecting block 31 and the second connecting block 23 are arranged vertically and correspondingly. The elastic member 6 is connected to the first connecting block 31 at one end and to the second connecting block 23 at the other end. The elastic member 6 is a tension spring, with one end hooked on the first connecting block 31 and the other end hooked on the second connecting block 23. In this embodiment, the limiting groove 22 is vertically provided in the middle of the bottom wall of the limiting seat 2. The elastic member 6 is a tension spring with hooks at both ends. One end of the elastic member 6 is hooked on the first hanging groove of the first connecting block 31, and the other end is hooked on the second hanging groove of the second connecting block 23. Both the first connecting block 31 and the second connecting block 23 are semicircular.

[0018] The middle portion of the snap block 4 is hinged to one end of the hinge block 5 via a first short pin 71. The other end of the hinge block 5 is hinged to the bottom of the handle 3 via a second short pin 72. The upper end of the snap block 4 is rotatably connected to the limit seat 2 via a long pin 8. The snap block 4 is wedge-shaped, with escape grooves 32 provided on both sides of the bottom of the handle 3. The bottom wall of the limit seat 2 is provided with arcuate escape portions 24 corresponding to the snap block 4. In this embodiment, the arcuate escape portions 24 are symmetrically arranged on both sides of the limit groove 22. The limit seat 2 is provided with mounting holes that adapt to the long pin 8 on both the front and rear sides.

[0019] The working process of the present invention is as follows: in the locked state: the handle 3 is at the lowest point, the elastic member 6 is in a naturally suspended state, the outer ends of the buckle blocks 4 on both sides extend out of the through slots 21 and are limited in the buckle slots 11. When there is a tendency to move outward, the upper ends of the buckle blocks 4 contact the ends of the buckle slots 11 on the inner wall of the base 1, and self-locking is achieved by blocking each other;

[0020] Unlocking the state: Pull the handle 3 outward, the buckle block 4 rotates around the long pin 8 in the limit seat 2, and the bottom ends of the buckle blocks 4 on both sides of the handle 3 slide from the outside to the inside on the arc-shaped avoidance portion 24. The buckle block 4 gradually rotates to the bottom of the handle 3 through the hinge block 5 and contacts the bottom wall of the handle 3. The outer corner of the buckle block 4 gradually retracts from the buckle groove 11 into the limit seat 2, and the locking state of the buckle block 4 is released. At the same time, when the handle 3 is pulled, the elastic member 6 at its bottom is stretched, and the elastic member 6 drives the limit seat 2 to move up and out of the base 1 until the limit seat 2 is completely separated from the base 1.

[0021] The utility model simplifies the actions and steps of modular battery disassembly and assembly, shortens the disassembly and assembly time, and can complete the disassembly and assembly without additional tools or parts. The force exerted on key parts during fixation is shear force, and the same material can generate several times the fixing force, thereby extending the life of parts and increasing the durability of the system. The fixing structure occupies a small space and has a high degree of modularity, and can be applied to a variety of usage scenarios. The fixing structure of the modular battery is integrated with the battery itself, making the battery shape more regular and easier to industrialize.

[0022] Finally, it should be emphasized that the above description is not intended to limit the present invention. For those skilled in the art, the present invention may have various changes and modifications. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
