Description

Technical Field

[0001] This application relates to the field of batteries, and more particularly to a quick-release battery structure for electric bicycles. Background Technology

[0002] As an important tool for green transportation, the convenience and safety of electric bicycle batteries have always been key concerns for users. Currently, common electric bicycle battery installation methods on the market mainly include screw fixing, clip fixing, and plug-in fixing. These methods meet the battery fixing requirements to a certain extent, but in actual operation, the battery pack needs to be aligned with the installation part. Misalignment will prevent installation, requiring realignment, sometimes even multiple times, thus affecting installation efficiency. Utility Model Content

[0003] To improve installation efficiency, this application provides a quick-release electric bicycle battery structure.

[0004] This application provides a quick-release electric bicycle battery structure, which adopts the following technical solution:

[0005] A quick-release electric bicycle battery structure includes a battery pack and a mounting plate. The mounting plate is used to install on the frame of the electric bicycle. The mounting plate is provided with a first magnetic block, and the bottom of the battery pack is provided with a second magnetic block. The second magnetic block can be attracted to the first magnetic block. The mounting plate is provided with a limiting component for limiting the position of the battery pack.

[0006] By adopting the above technical solution, a first magnetic block is provided on the mounting plate and a second magnetic block is provided on the battery pack. When installing the battery pack, the first magnetic block can attract the second magnetic block, thereby quickly positioning the battery pack. Then, the battery pack is fixedly installed by the limiting component, which can improve the convenience and efficiency of installation.

[0007] Optionally, the limiting component includes two limiting frames, which are L-shaped and arranged opposite to each other. The first magnetic block is located between the two limiting frames. The lower end of the limiting frame is hinged to the mounting plate, and the free ends of the two limiting frames can be engaged with each other.

[0008] By adopting the above technical solution, after the battery pack is positioned, it needs to be fixedly installed. At this time, the two limiting brackets are rotated, and the free ends of the two limiting brackets are fixed to each other, thereby fixing the battery pack in place.

[0009] Optionally, the two limiting frames are staggered along the length of the battery pack, and a limiting plate is provided on the battery pack. The limiting plate is located between the two limiting frames, and the two limiting frames abut against the two sides of the limiting plate to limit the movement of the battery pack along the length.

[0010] By adopting the above technical solution, a limiting plate is provided on the battery pack. When the two limiting frames are interlocked, the two limiting frames abut against the two sides of the limiting plate, thereby limiting the displacement of the battery pack along its length direction and improving the stability of the battery pack installation.

[0011] Optionally, the two limiting frames are a first limiting frame and a second limiting frame, with a locking rod slidably connected on the first limiting frame, and the limiting plate having a first locking hole for the locking rod to be locked.

[0012] By adopting the above technical solution, a locking rod is provided on the first limiting frame, and the locking rod is locked in the first locking hole on the limiting plate, thereby fixing the first limiting frame and the limiting plate.

[0013] Optionally, the first limiting frame is provided with an elastic element that forces the locking rod to slide.

[0014] By adopting the above technical solution, the elastic element forces the locking rod to lock into the first locking hole, thereby improving the stability of the limit.

[0015] Optionally, the lower surface of the second limiting frame is provided with a first locking groove in the vertical direction for locking the locking rod. The width of the first locking groove is greater than the diameter of the locking rod. The second limiting frame is slidably connected to a limiting block for limiting the locking rod located in the first locking groove. The second limiting frame is provided with a driving component for driving the limiting block to slide.

[0016] By adopting the above technical solution, after the first limiting frame and the battery pack are installed, the second limiting frame is rotated. At this time, the locking rod will be locked in the first locking groove. Then, the limiting block is driven by the driving component to slide, so that the limiting block limits the locking rod, thereby fixing the free ends of the first limiting frame and the second limiting frame, thus realizing the fixed installation of the battery pack.

[0017] Optionally, a limiting groove is provided on the side of the limiting block near the hinge end of the second limiting frame, and the limiting groove is V-shaped.

[0018] By adopting the above technical solution, the V-shaped groove of the limiting slot improves the limiting stability of the limiting block on the locking rod.

[0019] Optionally, the drive assembly includes a lead screw and a knob. The lead screw is threaded through the second limiting frame, one end of the lead screw is rotatably connected to the limiting block, and the knob is coaxially disposed on the lead screw.

[0020] By adopting the above technical solution, the transmission screw is rotated by turning the knob, thereby driving the limit block to slide.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] 1. A first magnetic block is provided on the mounting plate, and a second magnetic block is provided on the battery pack. When installing the battery pack, the first magnetic block can attract the second magnetic block to quickly position the battery pack. Then, the battery pack is fixedly installed by the limiting component, which can improve the convenience and efficiency of installation.

[0023] 2. After the first limiting frame and the battery pack are installed, rotate the second limiting frame. At this time, the locking rod will be locked in the first locking groove. Then, the limiting block is driven by the driving component to slide, so that the limiting block limits the locking rod, thereby fixing the free ends of the first and second limiting frames, thus realizing the fixed installation of the battery pack.

[0030] This application discloses a quick-release electric bicycle battery structure. (Refer to...) Figure 1 and Figure 2The device includes a battery pack 2 and a mounting plate 1. The mounting plate 1 is used to fix the device to the frame of the electric bicycle. A first magnetic block 11 is fixedly connected to the upper surface of the mounting plate 1. The length direction of the first magnetic block 11 is parallel to the length direction of the mounting plate 1. A second magnetic block 12 is fixedly connected to the bottom of the battery pack 2. The length direction of the second magnetic block 12 is parallel to the length direction of the battery pack 2. The second magnetic block 12 can be attracted to the first magnetic block 11. A limiting component is provided on the mounting plate 1 to limit the position of the battery pack 2.

[0031] Reference Figure 1 and Figure 3 The limiting assembly includes two L-shaped limiting frames distributed along the width of the mounting plate 1. A first magnetic block 11 is located between the two limiting frames. The two limiting frames face each other and are staggered along the length of the mounting plate 1. The lower ends of the limiting frames are hinged to the mounting plate 1. After the battery pack 2 is installed on the mounting plate 1, the two limiting frames are rotated to limit its movement.

[0032] The two limiting frames are a first limiting frame 3 and a second limiting frame 4. A limiting plate 21 is fixedly connected to the upper surface of the battery pack 2. The length direction of the limiting plate 21 is parallel to the width direction of the battery pack 2. When the battery pack 2 is installed on the mounting plate 1, the limiting plate 21 is located between the first limiting frame 3 and the second limiting frame 4. The first limiting frame 3 and the second limiting frame 4 abut against the two sides of the limiting plate 21 to limit the movement of the battery pack 2 along its length. A first sliding hole 31 is provided through the first limiting frame 3. The length direction of the first sliding hole 31 is parallel to the length direction of the mounting plate 1. The first limiting frame 3 is provided with a locking rod 32 that is slidably connected to the first sliding hole 31. The limiting plate 21 is provided with a first locking hole for the locking rod 32 to be locked.

[0033] The first limiting frame 3 is provided with an elastic element that forces the locking rod 32 to slide. The elastic element is a spring 33. The spring 33 is located on the side of the first limiting frame 3 away from the second limiting frame 4. One end of the spring 33 is fixedly connected to the first limiting frame 3, and the other end of the spring 33 is fixedly connected to the locking rod 32.

[0034] Reference Figure 1 and Figure 4 The lower surface of the cantilever side of the second limiting frame 4 is vertically provided with a first locking groove 41 for locking the locking rod 32. The width of the first locking groove 41 is greater than the diameter of the locking rod 32, so that during the rotation of the second limiting frame 4, the locking rod 32 can be locked in the first locking groove 41 and abut against the side wall of the first locking groove 41. The second limiting frame 4 is slidably connected to a limiting block 42 for limiting the locking rod 32 located in the first locking groove 41. The second limiting frame 4 is provided with a driving assembly 5 for driving the limiting block 42 to slide.

[0035] Reference Figure 1 and Figure 4 The drive assembly 5 includes a lead screw 51 and a knob 52. The axis of the lead screw 51 is parallel to the width direction of the mounting plate 1. The lead screw 51 is threaded through the second limiting bracket 4 and extends into the first locking groove 41. The limiting block 42 is located in the first locking groove 41. One end of the lead screw 51 is rotatably connected to the limiting block 42. The side of the limiting block 42 away from the mounting plate 1 abuts against the side wall of the first locking groove 41. The knob 52 is coaxially fixedly connected to the other end of the lead screw 51 away from the lead screw.

[0036] Reference Figure 1 and Figure 4 The limiting block 42 has a limiting groove on the side near the hinge end of the second limiting frame 4. The limiting groove is V-shaped and the locking rod 32 can be locked in the limiting groove.
