Description

Technical Field

[0001] This utility model relates to the field of battery pack technology, specifically a battery pack assembly / disassembly structure and a battery pack. Background Technology

[0002] In various battery-powered robots, tools, and other devices, replaceable battery packs are often used. This necessitates the design of a disassembly and assembly structure between the battery pack and the device. Common disassembly and assembly structures typically include buckles and latches between the battery pack and the device. When it is necessary to remove the battery pack, the buckles and latches must first be unlocked, and then the battery must be picked up and removed. This requires two steps. In addition, it is inconvenient to handle batteries that are large or heavy.

[0003] Therefore, this application proposes a battery pack disassembly and assembly structure and a battery pack that can remove the battery in a coordinated manner. Compared with the prior art, the operation can be completed in one step. In addition, it is also more convenient to handle when the battery is large or heavy. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the defects of the prior art and propose a battery pack disassembly and assembly structure and battery pack that can remove the battery in a coordinated manner. Compared with the prior art, the operation can be completed in one step. In addition, it is also more convenient to handle when the battery is large or heavy.

[0005] Compared with the prior art, this utility model proposes a battery pack disassembly and assembly structure, including:

[0006] The carrying strap is attached to the battery pack and is used to lift the battery pack.

[0007] The first connector is located on the battery pack and connected to the carrying strap. When the carrying strap lifts the battery pack, it simultaneously drives the first connector.

[0008] The second connector is located at the battery pack mounting port and is detachably connected to the first connector. When the battery pack is lifted by the carrying strap, the first connector is activated to unlock the connection between the first connector and the second connector, and the battery pack is removed from the battery pack mounting port under the lifting strap.

[0009] Compared with the prior art, the present invention has the following advantages after adopting the above structure:

[0010] This disclosure improves upon existing technology by using a lifting strap to link the first connector, thereby unlocking the first connector from the second connector. After unlocking, the lifting action of the strap pulls out the battery pack. Therefore, this disclosure can remove the battery in one step compared to existing technologies. In addition, it is more convenient to handle large or heavy batteries.

[0011] In some embodiments, a carrying strap spans over the battery pack, and a first connector is located at the end of the carrying strap.

[0012] In some embodiments, there are two first connectors, corresponding to the two ends of the carrying strap respectively.

[0013] In some embodiments, a reset structure is also included, which is connected to the first connector and causes the first connector to return to the locked position when the carrying strap is released.

[0014] In some embodiments, the first connector is a telescopic latch and the second connector is a snap-fit ​​part. When the battery pack is placed into the mounting port, the telescopic latch is pulled back by the carrying strap to allow the battery pack to be placed into the mounting port. At the same time, when the battery pack is placed into the mounting port and the carrying strap is released, the telescopic latch and the snap-fit ​​part are engaged by the reset structure, and the carrying strap is reset.

Therefore, the above terms should not be construed as limitations on this utility model.

[0030] like Figures 1 to 12 As shown, this disclosure proposes a battery pack disassembly and assembly structure, including:

[0031] Carrying strap 1 is connected to battery pack 2 and is used to lift battery pack 2.

[0032] The first connector 3 is located on the battery pack 2 and connected to the carrying strap 1. When the carrying strap 1 lifts the battery pack 2, it simultaneously drives the first connector 3.

[0033] The second connector 4 is located at the mounting port 5 of the battery pack 2 and is detachably connected to the first connector 3. When the carrying strap 1 lifts the battery pack 2, the first connector 3 is activated to unlock the connection between the first connector 3 and the second connector 4, and the battery pack 2 is removed from the mounting port 5 of the battery pack 2 under the lifting of the carrying strap 1.

[0034] In this example, as Figure 7 , 8 As shown, this disclosure is applied to a device, such as a robot. The device includes an upward-opening mounting port 5. A second connector 4 is provided on the inner wall of the mounting port 5. The second connector 4 uses a snap-fit ​​as a locking part, while the first connector 3 uses a telescopic snap-fit. When the battery pack 2 is placed into the mounting port 5 from top to bottom, the telescopic snap-fit ​​is pulled back by the carrying strap 1 to allow the battery pack 2 to be placed into the mounting port 5. At the same time, when the battery pack 2 is placed into the mounting port 5 and the carrying strap 1 is released, the telescopic snap-fit ​​engages with the locking part under the action of the reset structure, and the carrying strap 1 resets. In this way, the battery pack 2 can be quickly installed in place.

[0035] In some embodiments, such as Figure 4 As shown, in order to facilitate electrical connection, the battery pack 2 is provided with a downward-facing connection terminal 9. When the battery pack 2 is placed into the mounting port 5, the connection terminal 9 is inserted downward into the mating terminal in the mounting port 5, and then the electrical connection can be completed, thereby improving the convenience of connection.

[0036] In some embodiments, such as Figure 2 , 6 As shown, the reset structure uses spring 6.

[0037] In some embodiments, such as Figure 2 , 3 As shown, the carrying strap 1 spans across the top of the battery pack 2, and the first connector 3 is located at the end of the carrying strap 1. This allows for better application of force to lift / lower the battery pack 2, making operation more convenient. In addition, it makes it easier to align the battery with the mounting port 5 when inserting the battery.

[0038] In some embodiments, such as Figure 2 , 5 As shown, there are two first connectors 3, corresponding to the two ends of the carrying strap 1 respectively. In this way, the two first connectors 3 move simultaneously under the action of the carrying strap 1, thereby realizing the unlocking / locking solution at both points, which can better install and fix the battery pack 2 in the mounting port 5.

[0039] In some embodiments, such as Figure 2 , 6 As shown, it also includes a reset structure, which is connected to the first connector 3. When the carrying strap 1 is released, the reset structure causes the first connector 3 to return to the locked position, which is the extended position.

[0040] In some embodiments, the carrying strap 1 is made of flexible plastic, which improves manufacturing efficiency and helps reduce costs.

[0041] Of course, in addition to plastic tapes, tapes can also be made of silicone tapes, cloth tapes, or other materials. Any tape suitable for this disclosure can be used in this disclosure.

[0042] For added comfort, the carrying strap 1 is further fitted with a protective sleeve 8.

[0043] like Figures 1 to 12 As shown, this disclosure proposes a battery pack 2, including: a carrying strap 1, which is connected to the battery pack 2 for lifting the battery pack 2; and a first connector 3, which is disposed on the battery pack 2 and connected to the carrying strap 1, and when the carrying strap 1 lifts the battery pack 2, it simultaneously drives the first connector 3.

[0044] In this example, the carrying strap 1 of the battery pack 2 spans across the top of the battery pack 2, and the first connector 3 is located at the end of the carrying strap 1. There are two first connectors 3, corresponding to the two ends of the carrying strap 1 respectively.

[0045] The battery pack 2 also includes a reset structure connected to the first connector 3. When the carrying strap 1 is released, the reset structure causes the first connector 3 to return to the locked position.

[0046] In some embodiments, such as Figure 2 , 5 As shown, the first connector 3 adopts a telescopic latch. When the carrying strap 1 is pulled, the telescopic latch retracts under the action of the carrying strap 1. When the carrying strap 1 is released, the telescopic latch extends under the action of the reset structure, and the carrying strap 1 resets.

[0047] In some embodiments, such as Figure 2 , 5 As shown, the first connector 3 is provided with a connecting hole 10, through which the end of the carrying strap 1 passes to form a fold-back portion 15. In this way, the connection is simple and the assembly is convenient.

[0048] In some embodiments, such as Figure 2 , 3 As shown in Figures 5 and 6, the battery pack 2 includes a cover plate 16 and a housing 17. The cover plate 16 and the housing 17 are connected in the vertical direction. For example, multiple buckles 12 are provided on the housing 17 to connect the cover plate 16 for snap-fit ​​connection.

[0049] Before the cover plate 16 is connected to the housing 17, it is necessary to study how to more conveniently and efficiently install the first connector 3 and the carrying strap 1 in batches. Therefore, this disclosure proposes a technical solution, specifically, as follows: Figure 5 , 6As shown in Figures 9, 10, 11, and 12, the package also includes a pressure cap 13 located below the cover plate 16. The cover plate 16 has a through hole 19. One end of the carrying strap 1 passes through the through hole 19 and the connecting hole 10 in sequence to form a folded-back portion 15. The carrying strap 1 is thus threaded through and connected to the first connecting member 3. Then, the cover plate 16 and the pressure cap 13 are connected in the vertical direction to form the first component. The second component includes a housing 17. The first component and the second component are connected to each other through the cover plate 16 and the housing 17 to form the outer shell of the battery pack 2. As described above, the cover plate (16) and the housing 17 are connected by multiple snap fasteners 12 to improve the convenience of connection.

[0050] Furthermore, the pressure cap 13 is provided with a clamping structure and a guide groove portion forming the guide groove 7. The guide groove 7 accommodates the first connecting member 3 and the fold-back portion 15. When the cover plate 16 and the pressure cap 13 are connected in the vertical direction, the first connecting member 3 is guided and limited in the guide groove 7, and extends and retracts through the telescopic port 18. The clamping structure then clamps and fixes the fold-back portion 15 to the lower side of the cover plate 16. This greatly facilitates manufacturing, helps ensure production quality, and also helps reduce costs.

[0051] In some embodiments, for easier and more precise assembly, such as Figure 2 , 10 As shown, a baffle 21 is provided on the lower side of the cover plate 16, and one end of the carrying strap 1 is set as an L-shaped end 22. After passing through the through hole 19 and the connecting hole 10 in sequence, the L-shaped end 22 extends further to the baffle 21 and hooks onto the baffle 21 for temporary fixation. Then, the pressure cap 13 is added to further fix the folded-back part 15, thereby fixing both ends of the carrying strap 1 more precisely. It is possible to consider injection molding the L-shaped end 22 at the same time as injection molding the carrying strap 1.

[0052] In some embodiments, to avoid interference between the retraction portion 15 and the spring 6 of the reset structure, and to better limit the retraction portion 15, such as... Figure 10 As shown, it also includes a guard plate 23, which is located on both sides of the fold-back portion 15. The fold-back portion 15 is accommodated between the two guard plates 23, and a spring 6 with a reset structure is provided on the outer side of the two guard plates 23.

[0053] In some embodiments, such as Figure 2 , 6 As shown, the clamping structure uses a clamping strip 11. When the cover plate 16 and the pressure cover 13 are connected in the vertical direction, the clamping strip 11 presses the folded-back part 15 upward and fixes it to the lower side of the cover plate 16.

[0054] Furthermore, such as Figure 2 As shown, in order to better fix the folded-back part 15, the cover plate 16 is provided with a top pressing groove 14 on the lower side, that is, a pressing groove.

[0055] Of course, other structures are also possible. For example, a clamping strip 11 can be provided on the underside of the cover plate 16, and a clamping mating surface can be provided on the pressure cap 13. Alternatively, a clamping strip 11 can be provided on the underside of the cover plate 16, and a clamping mating groove can be provided on the pressure cap 13. In short, any clamping structure applicable to this disclosure can be applied to this disclosure.

[0056] In this example, there are two first connectors 3. Preferably, there are two corresponding pressure caps 13. In this way, there is a gap between the two pressure caps 13, which does not affect the other structure of the battery pack 2 and helps to save the internal space of the battery pack 2.

[0057] Furthermore, since the two pressure caps 13 are spaced apart, the cover plate 16 can have a recess 20 on its upper side without increasing its thickness. This recess 20 is used to accommodate the carrying strap 1. In this way, on the one hand, the carrying strap 1 can be flush with or lower than the upper side of the cover plate 16, so that the carrying strap 1 is not obtrusive in the recess 20. On the other hand, it protects the carrying strap 1, so that the carrying strap 1 is not easily scratched by other items and accidentally moved.

[0058] When understanding this disclosure, the above structure may be referred to other embodiments / appendices if necessary. Figure 1 And that's understood, so I won't go into details here.

[0059] The above description is merely an illustrative embodiment of this utility model. Therefore, all equivalent changes or modifications made to the structure, features, and principles described in the scope of protection of this utility model are included within the scope of protection of this utility model.
