Description

Technical Field

[0001] This utility model relates to the field of electric bicycle technology, and in particular to a battery box and an electric bicycle. Background Technology

[0002] The battery is the power source of an electric bicycle. Most electric bicycles use rechargeable batteries, which are rechargeable and reusable. These batteries can power not only electric bicycles but also other devices. Therefore, when unattended, electric bicycle batteries are often stolen by criminals for illicit gains. Consequently, most electric bicycles now have a lockable battery compartment on the outside of the battery, both to protect the battery from environmental damage and to prevent theft.

[0003] In existing technology, the battery of an electric vehicle is usually located inside the battery box of an electric bicycle and locked in place by a locking mechanism. When it is necessary to remove the battery, the locking mechanism is opened and the battery can be removed. To facilitate automatic opening of the locking mechanism, it can also be set as an electronic Bluetooth lock, connecting to devices such as mobile phones via a built-in Bluetooth module, enabling automatic unlocking of the electronic Bluetooth lock via a mobile phone, simplifying the unlocking process. However, the battery lock is also an electronic component that requires power to operate, and its power source is usually the battery itself. Therefore, when the battery is depleted, the battery lock will also stop working due to lack of power, causing the electric bicycle's battery box to lock. When the battery malfunctions and needs repair, but the battery cannot supply power to the battery lock, the battery will be locked inside the box, making it impossible to remove without force, which greatly hinders battery repair work.

[0029] This utility model proposes a battery box 100.

[0030] Please see Figure 1-6 In one embodiment of this utility model, the battery box 100 includes: a box body 1, a mounting base 2, a battery lock 3, and a box cover 4; the box body 1 has a battery compartment with an open side; the mounting base 2 is disposed inside the box body 1, and the mounting base 2 has a locked state that is locked with the box body 1 and an unlocked state that is released from the box body 1; the box body 1 is provided with a disassembly part for unlocking the mounting base 2 from the outside; the battery lock 3 is disposed inside the box body 1 and is fixedly connected to the mounting base 2; the box cover 4 is detachably disposed on the open side of the battery compartment, and the battery lock 3 is used to lock or release the box cover 4.

[0031] In this embodiment, the housing 1 has an upward-opening battery compartment. The battery and the ejector mechanism of the cover 4 are installed inside the battery compartment. The opening of the battery compartment has a cover groove that matches the shape of the cover 4. The cover 4 is fastened into the cover groove to close the opening of the battery compartment. During daily use, the mounting base 2 remains locked to the housing 1. The battery lock 3 can be remotely controlled to open and close via a mobile phone or remote control, and the ejector mechanism of the cover 4 inside can be operated to pop up the cover 4 to remove the cover 4 for charging the battery. When the battery is depleted or malfunctions, the power supply can no longer provide power to the battery lock 3, and the battery lock 3 can no longer be controlled to open or close via external devices. At this time, the mounting base 2 and the housing 1 can be separated by changing their states. Even if the battery lock 3 and the housing cover 4 remain locked, by disassembling the mounting base 2 and the housing 1, the housing cover 4 can lift the battery lock 3 and the mounting base 2 connected to the battery lock 3 together. This allows the housing cover 4 to be separated and disassembled from the housing 1 even when the battery lock 3 cannot be opened under power. At this time, the operator can repair the battery in the battery compartment by disassembling the mounting base 2.

[0032] The technical solution of this utility model involves setting a box body 1 and a box cover 4 in a battery box 100, and installing the battery lock 3 inside the box body 1 through the mounting base 2, so that the box cover 4 can close the battery compartment of the box body 1 and lock it to the box body 1; and by having the mounting base 2 and the box body 1 in a locked state and an unlocked state, the battery lock 3 together with the mounting base 2 can be separated from the box body 1; when the battery cannot supply power to the battery lock 3, since the battery lock 3 is still locked to the box cover 4, the box cover 4 cannot be opened directly, but maintenance personnel can remove the mounting base 2 from the outside of the box body 1 by changing the locking state of the mounting base 2 and the box body 1, so that the mounting base 2 and the battery lock 3 can be removed together with the box cover 4, avoiding the situation where the battery is locked inside the box and cannot be repaired.

[0033] See Figure 1 and 5 In this embodiment, the battery lock 3 has a groove on the side near the cover 4, and a latch is provided in the groove. The cover 4 includes a cover body 41 and a connecting part 42. The connecting part 42 is located on the side of the cover body 41 facing the battery. The connecting part 42 is used to insert into the groove and cooperate with the latch. The latch is used to lock or release the connecting part 42 under electric drive. The latch in the groove extends and retracts between the grooves by electric control. When the connecting part 42 of the cover 4 is inserted into the groove, the latch passes through the groove of the cover 4. When the latch is retracted in the groove by electric control, the cover 4 will pop up under the action of the pop-out device. After popping up, the latch is pulled out again. At this time, even if the cover 4 falls under the action of gravity and the connecting part 42 falls back into the groove, the latch can still limit the connecting part 42, so that the cover 4 always protrudes from the top of the box body 1, avoiding the situation where the cover 4 is re-fastened to the cover groove and is difficult to pry out.

[0034] See Figure 1 and 5 In this embodiment, the connecting part 42 includes a fixing plate 421, a locking ring 422, and a connector 423. The locking ring 422 is fixedly connected to the side of the fixing plate 421 near the battery lock 3, and the connector 423 is fixedly connected to the side of the fixing plate 421 away from the locking ring 422. The connector 423 is fixedly connected to the cover 41. The locking ring 422 is connected to one side of the fixing plate 421 by welding or integral molding to enhance structural stability and prevent the cover 4 from breaking and thus failing to lock with the battery lock 3. In other embodiments, the locking ring 422 can also be a metal plate with holes or grooves, as long as the latch can be inserted into the holes or grooves to limit the connection part 42. The side of the cover 41 facing the battery lock 3 has a groove for the connector 423 to be inserted, so that the connecting part 42 can be detachably connected to the inside of the cover 4. The groove and the connector 423 are connected by threads, which facilitates the disassembly or replacement of the connecting part 42.

[0035] Reference Figure 6 In this embodiment, the mounting base 2 includes a base 21 and a support plate 22. The support plate 22 is located above the base 21. The lower end face of the base 21 has a mounting hole 211. The disassembly part is a disassembly hole located on the housing 1 and corresponding to the mounting hole 211. The disassembly hole and the mounting hole 211 are used for fasteners 23 to pass through. The fasteners 23 are used to detachably connect the mounting base 2 and the housing 1. The base 21 is used to connect to the bottom of the housing 1. The base 21 and the support plate 22 can be integrally formed or welded together. In this embodiment, the base 21 and the support plate 22 are integrally formed to enhance the stability of the structure. A chamfer is provided at the connection between the base 21 and the support plate 22 to further enhance the connection stability between the support plate 22 and the base 21. The bottom of the base 21 has a mounting hole 211 that matches the size of the fastener 23. The size of the disassembly hole is the same as or slightly larger than the size of the mounting hole 211 so that the fastener 23 can pass smoothly through the disassembly hole and be fastened to the mounting hole 211.

[0036] In this embodiment, the fastener 23 is connected to the mounting hole 211 by a thread. The fastener 23 can be a bolt or screw, and the mounting hole 211 is a threaded hole. Applying external force to the fastener 23 on the outside of the housing 1 will loosen the fastener 23. In other embodiments, when the mounting hole 211 is a through hole 221, the fastener 23 can be a stud. In this case, neither the mounting hole 211 nor the disassembly hole needs to be threaded; a through hole 221 with a size larger than a stud but smaller than a nut is sufficient. In other embodiments, the mounting base 2 can also be connected to the housing 1 by a latch or pin. The disassembly part at the bottom of the housing 1 can be provided with a groove facing the battery compartment. The force-applying end of the fastener 23 is placed in the groove, and an anti-theft cover that can be opened is provided at the opening of the groove. Normally, the cover 4 is automatically opened remotely. When the battery cannot power the battery lock 3, opening the anti-theft cover can separate the mounting base 2 from the housing 1, allowing the cover 4, battery lock 3, and mounting base 2 to be removed.

[0037] In this embodiment, the support plate 22 is provided with a through hole 221, and a fastener 23 is inserted into the through hole 221. The battery lock 3 is fixedly installed on the support plate 22 by the fastener 23. The back plate of the battery lock 3 fits and abuts against the support plate 22 to increase the connection strength between the battery lock 3 and the support part 213 and save internal space in the battery compartment. When the battery lock 3 malfunctions, the fastener 23 can be loosened to remove the battery lock 3 from the mounting base 2, or the battery lock 3 can be removed without removing the fastener 23.

[0038] In this embodiment, the base 21 has a balancing part 212 and a supporting part 213, which are respectively disposed on both sides of the support plate 22. The supporting part 213 is disposed on the side of the support plate 22 closer to the battery lock 3. The supporting part 213 is disposed below the battery lock 3 to support the weight of the battery lock 3 to further prevent the battery lock 3 from detaching. The balancing part 212 is disposed on the other side to prevent the support plate 22 and the battery lock 3 from tilting to the other side, thereby balancing the weight of the battery lock 3 and supporting both sides of the support plate 22.

[0039] In this embodiment, the support portion 213 and / or the balancing portion 212 are provided with mounting holes 211. In this embodiment, at least two support portions 213 are provided at intervals along the horizontal extension direction of the support plate 22, and the lower end face of each support portion 213 is provided with mounting holes 211. The number of support portions 213 can be increased or decreased according to the weight of the battery lock 3 to improve the stability of the mounting base 2. The balancing portion 212 is provided on the side of the support plate 22 away from the support portion 213, and the lower end face of the balancing portion 212 is provided with mounting holes 211. In order to reduce the processing steps, the mounting portion may not have mounting holes 211, which can still balance the weight of the battery lock 3. The addition of mounting holes 211 and fasteners 23 can further restrict the horizontal movement of the mounting base 2, so that the mounting base 2 is more stably placed in the battery compartment. In addition, the number and size of the balancing portion 212 can also be increased or decreased according to the actual use.

[0040] In this embodiment, one end of the lid 4 is inserted into the box body 1, and the other end of the lid 4 is detachably connected to the battery lock 3. One end of the lid 4 is inserted into a lid slot on the top of the box body 1, so that the lid 4 can be flush with the top of the box body 1, and when the battery lock 3 is locked, the lid 4 cannot be opened from the other side, thus achieving the purpose of locking. In other embodiments, the end of the lid 4 away from the battery lock 3 can also be rotatably connected to the box body 1 by means of hinges or the like.

[0041] This utility model also proposes an electric bicycle, which includes a bicycle and a battery box 100. The specific structure of the battery box 100 is as described in the above embodiments. Since this electric bicycle adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.
