[0002] With the development of shared two-wheelers, many of these vehicles now require frequent battery pack replacements. However, frequent battery pack replacements can easily damage the external connectors. Currently, the main repair method for damaged external connectors is to disassemble the entire battery pack and replace the connectors, which reduces the efficiency and convenience of battery pack maintenance. Utility Model Content

[0003] To address the aforementioned problems in the prior art, this utility model provides a quick-replaceable external connector for a battery pack.

[0004] To achieve the above objectives, the main technical solutions adopted by this utility model include:

[0005] A quick-replaceable external connector for a battery pack includes a connector detachably connected to the battery pack; the connector has a male terminal on one side opposite the battery pack; the battery pack has a female terminal that mates with the male terminal; the female terminal has a protrusion facing the connector; a sealing strip is provided around the protrusion; a limiting plate is formed on the outer periphery of the male terminal; a connecting groove that mates with the protrusion is formed in the limiting plate; the limiting plate is tightly connected to the sealing strip; an external terminal is provided on the side of the connector away from the battery pack; the male terminal is connected to the external terminal through a connecting part; the extending direction of the connecting part is parallel to the extending direction of the connector.

[0006] In one embodiment of this utility model, multiple sealing strips are provided along the protruding direction of the female terminal.

[0007] In one embodiment of the present invention, the connecting groove includes a connecting groove bottom plate; the inner side of the end of the limiting plate away from the connecting groove bottom plate is provided with a chamfer.

[0008] In one embodiment of this utility model, the limiting plate is rectangular in shape and has an oblique angle that is different from the other three corners.

[0009] In one embodiment of this utility model, the female terminal and the male terminal constitute a pin connector.

[0010] In one embodiment of this utility model, the connector is provided with a plurality of connection holes in its circumferential direction; the connection holes are provided with screws for fixed connection with the battery pack.

[0011] In one embodiment of this utility model, the connector is provided with two oppositely arranged grooves.

[0024] Example:

[0025] A quick-replaceable external connector for a battery pack includes a connector 200 detachably connected to a battery pack 100; the battery pack 100 has a common battery pack structure in the art; the connector 200 has a male terminal 210 on one side opposite to the battery pack 100; in one embodiment, the connector 200 includes a faceplate 201 and a side plate 202 formed circumferentially around the faceplate 201; the faceplate 201 is disposed opposite to the battery pack 100; the male terminal 210 is disposed on the side of the faceplate 201 opposite to the battery pack 100. The side plate 202 extends towards the battery pack 100 on one side; the battery pack 100 is provided with a female terminal 110 that mates with the male terminal 210; the side plate 202 surrounds the female terminal 110 in the circumference to form circumferential protection, and combined with the face protection of the cover 201, when the connector 200 is connected to the battery pack 100, the connector 200 can form a closed protective structure outside the female terminal 110, which ensures the stability of the connection and avoids the influence of the external environment on the connection between the connector 200 and the battery pack 100.

[0026] In one embodiment, the female terminal 110 has a protrusion facing the connector 200; a sealing strip 120 is provided around the protrusion; a limiting plate 220 is formed on the outer periphery of the male terminal 210; a connecting groove 230 that mates with the protrusion is formed in the limiting plate 220; the limiting plate 220 and the sealing strip 120 are tightly connected; by setting the female terminal 110 as a protruding structure, additional limiting fit can be provided on the original pin-type structure; the tight fit between the limiting plate 220 and the sealing strip 120 can further increase the damping when the female terminal 110 and the male terminal 210 are connected, avoiding poor contact during vibration or under special circumstances; the sealing strip 120 can apply relatively stable pressure to the limiting plate 220, thereby ensuring that the position of the pin of the male terminal 210 and the female terminal 110 is relatively fixed when they are inserted; the sealing strip 120 can also provide a certain degree of waterproofing.

[0027] In one embodiment, multiple sealing strips 120 are provided along the protrusion direction of the female terminal 110, and the protrusion direction of the female terminal 110 is... Figure 1 By setting multiple sealing strips 120 from left to right, the damping during connection can be further increased, thus further enhancing connection stability.

[0028] In one embodiment, the connecting groove 230 includes a connecting groove bottom plate 231; the inner side of the end of the limiting plate 220 away from the connecting groove bottom plate 231 is provided with a chamfer 221. By setting the chamfer 221, the limiting plate 220 can achieve a guiding effect when it cooperates with the female terminal 110, which facilitates the quick connection between the female terminal 110 and the male terminal 210.

[0029] like Figure 2As shown, in one embodiment, the limiting plate 220 is rectangular in shape and has a bevel 222 that is different from the other three corners. By setting the special bevel 222 structure, the foolproof effect can be achieved to prevent the connector 200 from being installed in the wrong direction. In another embodiment, the limiting plate 220 is rectangular in shape and has three corners with rounded corners 223 and a bevel 222.

[0030] like Figure 3 As shown, in one embodiment, the connector 200 has an external terminal 250 on the side opposite to the battery pack 100; the male terminal 210 is connected to the external terminal 250 via a connecting portion 240; the extending direction of the connecting portion 240 is parallel to the extending direction of the connector 200. The extending direction of the connecting portion 240 is as follows: Figure 3 In the vertical direction, the extension direction of connector 200 is also... Figure 3 In the vertical direction, this structural design reduces the friction between the male terminal 210 and the external terminal 250. Figure 3 The volume occupied in the horizontal direction (thickness direction of connector 200) is reduced, thereby reducing the volume of connector 200; in one embodiment, the projections of the male terminal 210 and the external terminal 250 in the extension direction of connector 200 have an overlapping portion, that is, in Figure 3 Based on this, the external terminal 250 is moved to the left, thereby further reducing the thickness of the connector 200. Figure 3 (Dimensions in the horizontal direction), in this design, the thickness of connector 200 can be... Figure 3 The connector 200 shown is half the thickness.

[0031] In one embodiment of this utility model, the female terminal 110 and the male terminal 210 constitute a pin connector.

[0032] In one embodiment of this utility model, the connector 200 is provided with a plurality of connection holes 260 in its circumferential direction; the connection holes 260 are provided with screws 261 for fixed connection with the battery pack 100. The screws 261 can further enhance the connection stability between the connector 200 and the battery pack 100; however, the structure of the screws 261 is not necessary; in some embodiments, the battery pack 100 is usually disposed in a corresponding receiving groove, which can realize the limiting of the connector 200 and the battery pack 100 when connected, making the screws 261 unnecessary.

[0033] In one embodiment of this utility model, the connector 200 is provided with two oppositely arranged grooves 270. The grooves 270 facilitate the disassembly of the connector 200. It can be understood that the width direction of the connector 200 is typically... Figure 2The connection direction between the grooves 270 is larger than the opening size of the palm. When disassembling by hand, it is inconvenient to apply pressure with the hand. The grooves 270 can reduce the size in the width direction, thus making it easier to disassemble by hand.

[0034] In one embodiment of this utility model, the external terminal 250 is a knife-type connection terminal.

[0035] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent modifications made based on the content of this utility model specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of this utility model.
