Description

Technical Field

[0001] This utility model relates to the field of battery compartment technology, specifically to a battery anti-detachment mechanism. Background Technology

[0002] With the development of new energy technologies, electric vehicles are increasingly entering people's daily lives. Riders are also increasingly increasing their mileage by swapping batteries. As a result, batteries are becoming more and more important for electric vehicles, and ensuring battery safety during the battery swapping process is becoming increasingly important.

[0003] Currently, most battery swapping technologies are used on scooter models because the space under the seat is large and easy to operate. However, for motorcycles, when removing the battery box from the mounting frame, the operator must first use one hand to pry open the latch and then use the other hand to push the battery box from the back to the front to remove it. However, operators often fail to control the force of pushing the battery box forward properly or make a momentary lapse in attention, causing the entire battery box to slip and fall to the ground, resulting in damage to the battery box and its internal components, rendering it unusable. Utility Model Content

[0004] To overcome the above-mentioned shortcomings, the purpose of this utility model is to provide a battery anti-detachment mechanism to solve the problems mentioned in the background art.

[0031] refer to Figures 1 to 3 , Figure 1 This invention provides a three-dimensional representation of a battery anti-detachment mechanism 1 according to an embodiment of the present invention. Figure 1 ; Figure 2 This invention provides a three-dimensional representation of a battery anti-detachment mechanism 1 according to an embodiment of the present invention. Figure 2 Among them, the battery anti-detachment mechanism 1 is fixed to the battery 6; Figure 3 A partial structural schematic diagram of a battery anti-detachment mechanism 1 provided in an embodiment of the present invention is shown.

[0032] like Figures 1 to 3 As shown, Figure 1 The battery anti-detachment mechanism 1 is in its normal operating direction, meaning the base plate is positioned above the fixed battery 6. For ease of description, the following description will refer to the location of the base plate 2 as the bottom. Figure 2 As shown in the figure. The technical solution provided in this application is a battery anti-detachment mechanism 1, in which the battery 6 is positioned along a first direction ( Figure 1 Extending along the first direction (as shown in the X direction), the device has a first end cap 60 and a second end cap 61 at each end. The anti-detachment mechanism includes a base plate 2 and a connecting end cap 3. The base plate 2 has a first retaining seat 20 and a second retaining seat 21 at each end along the first direction, forming a placement space 22 for supporting and fixing the battery 6. The connecting end cap 3 is located on the side of the first end cap 60 away from the second end cap 61 and is engaged and fixed with the first retaining seat 20. The connecting end cap 3 includes an installation channel 30 and a pressing handle 4. The installation channel 30 extends along the first direction and is located at the top of the connecting end cap 3. The pressing handle 4 is located within the installation channel 30, and its bottom end is rotatably connected to the connecting end cap 3. The pressing handle 4 has an anti-detachment protrusion 42 on the side facing the first card seat 20, and the first card seat 20 has an anti-detachment groove 23 corresponding to the pressing handle 4 on the side facing the connecting end cover 3. When the connecting end cover 3 is separated from the first card seat 20, the anti-detachment protrusion 42 abuts against the anti-detachment groove 23 to limit the battery 6.

[0033] The battery anti-detachment mechanism 1 provided in this application fixes one side of the first end cap 60 of the battery 6 through the cooperation of the first latch 20 and the connecting end cap 3, and the other side of the second end cap 61 through the cooperation of the second latch 21, thereby fixing the battery 6 inside the battery anti-detachment mechanism 1. When the battery 6 is removed, by providing the anti-detachment protrusion 42 and the anti-detachment groove 23, the battery 6 is prevented from falling directly after unlocking, so that the battery 6 is kept in a state of not being completely detached, which facilitates subsequent operations on the battery 6.

[0034] In some embodiments, reference Figures 1 to 3 Press the handle 4 along the second direction ( Figure 1 Extending along the Z-direction (as shown), the two ends are a drive part 40 and a connecting part 41, respectively. The connecting part 41 is rotatably connected to the connecting end cover 3 and is provided with a rotating assembly. The bottom of the mounting channel 30 extends along the third direction (as shown). Figure 1 The rotating assembly (shown in the Y direction) has corresponding fixing grooves 31 at both ends. The rotating assembly includes an anti-detachment shaft 44, which extends along the third direction. Both ends are placed in the fixing grooves 31 and are fixedly connected to the connecting part 41. A stop block 46 is provided on the side of the fixing groove 31 facing the first end cover 60. The stop block 46 is widened in the direction away from the first end cover 60 to limit the anti-detachment shaft 44. The first direction, the second direction, and the third direction are perpendicular to each other.

[0035] For example, the pressing handle 4 can be rotated by the pressing drive part 40, so that after the anti-detachment protrusion 42 abuts and is fixed with the anti-detachment groove 23, the pressing drive part 40 causes the anti-detachment protrusion 42 to disengage from the anti-detachment groove 23, so as to remove the battery 6. The stop block 46 is extended in the direction away from the first end cover 60, and the two ends of the anti-detachment rotating shaft 44 are fixed in the fixing groove 31 by the cooperation of multiple stop blocks 46.

[0036] In some embodiments, reference Figures 1 to 3 The rotating assembly also includes an anti-detachment torsion spring 45. The connection between the connecting part 41 and the anti-detachment rotating shaft 44 is provided with an installation space. The anti-detachment torsion spring 45 is located in the installation space. One end is rotatably connected to the anti-detachment rotating shaft 44, and the other end is elastically abutted against the connecting part 41. It is used to elastically reset the pressing handle 4 after the driving part 40 is pressed.

[0037] For example, the anti-detachment torsion spring 45 can enhance the stability of the anti-detachment protrusion 42 when it abuts against the anti-detachment groove 23 by the restoring elastic potential energy generated after its rotation. In addition, by rotating the anti-detachment torsion spring 45 in the assembly, the pressing handle 4 can be elastically reset after pressing the driving part 40, which not only provides convenient operation, but also enhances the response speed of the mechanism and the user experience.

[0038] refer to Figures 4 to 6 , Figure 4 A perspective view of the first card holder 20 in a battery anti-drop mechanism 1 provided in an embodiment of the present invention is shown; Figure 5 A perspective view of the connecting end cap 3 in a battery anti-detachment mechanism 1 provided in an embodiment of the present invention is shown; Figure 6 A cross-sectional view of a battery anti-drop mechanism 1 provided in an embodiment of the present invention is shown, wherein the mechanical locking pin 24 is in a locked state.

[0039] In some embodiments, reference Figures 4 to 6 A shielding rib 43 is provided on the side of the pressing handle 4 facing the first end cover 60, and the shielding rib 43 is located between the driving part 40 and the connecting part 41. The first end cover 60 includes a limiting groove 62 and a clearance recess 63, both of which are provided on the side of the first end cover 60 facing the connecting end cover 3. The limiting groove 62 is correspondingly provided with the shielding rib 43, and the clearance recess 63 is correspondingly provided with the driving part 40.

[0040] For example, by pressing the drive part 40 to the shielding rib 43 against the limiting groove 62, the drive part 40 abuts against the avoidance recess 63, so that the anti-detachment protrusion 42 separates from the anti-detachment groove 23, thereby completely removing the battery 6 from the battery anti-detachment mechanism 1.

[0041] In some embodiments, reference Figures 4 to 6The connecting end cap 3 also includes an end cap locking hole 32 and a mechanical lock guide groove 33. The end cap locking hole 32 is located on the side of the connecting end cap 3 away from the first end cap 60 and below the mounting channel 30. The mechanical lock guide groove is located at the bottom of the end cap locking hole 32 and extends obliquely towards the bottom of the connecting end cap 3 in a direction close to the first end cap 60.

[0042] Furthermore, the first card holder 20 also includes a mechanical locking pin 24 and a lock cylinder 25. The mechanical locking pin 24 extends along a first direction and passes through the first card holder 20, corresponding to the locking hole 32 of the end cover. The end of the mechanical locking pin 24 away from the connecting end cover 3 has a mating groove 28, and the end closer to the connecting end cover 3 has an inclined portion. The inclined portion is corresponding to the mechanical lock guide groove 33. The lock cylinder 25 is located on the same side as the mating groove 28 and is connected to the mating groove 28. It is used to drive the mechanical locking pin 24 to move relative to the first card holder 20 along the first direction by rotating the lock cylinder 25, so that the mechanical locking pin 24 switches between a locked state and an unlocked state.

[0043] For example, in the locked state, one end of the mechanical locking pin 24 is placed inside the end cap locking hole 32; in the unlocked state, the mechanical locking pin 24 is separated from the end cap locking hole 32, which is used to separate the battery 6 from the first card holder 20 by pressing the drive part 40 in the unlocked state. The mechanical locking structure composed of the mechanical locking pin 24 and the lock cylinder 25 is a commonly used technical means in the prior art to protect the battery 6 of the vehicle body. The battery anti-drop mechanism 1 provided in this solution is for anti-drop treatment in the unlocked state. In the unlocked state, the mechanical locking pin 24 extends out from the end cap locking hole 32, and the first end cap 60 side of the battery 6 rotates downward due to its own gravity. Since the rotation path is arc-shaped, a mechanical lock guide groove 33 is provided to guide the mechanical locking pin 24 to avoid it. At the same time, the inclined part of the mechanical locking pin 24 is correspondingly set with the mechanical lock guide groove 33, which facilitates the separation and installation of the battery 6 and the battery anti-drop mechanism 1, and improves assembly efficiency.

[0044] In some embodiments, reference Figures 3 to 6 The battery anti-detachment mechanism 1 also includes an auxiliary guiding structure, which includes guide ribs 50 and assembly guide grooves 51. The guide ribs 50 extend along a second direction and are respectively located on both sides of the end cap locking hole 32 along a third direction. The assembly guide grooves 51 extend along the second direction and are respectively located on both sides of the anti-detachment groove 23 along a third direction. The assembly guide grooves 51 and guide ribs 50 are arranged in a one-to-one correspondence, allowing the guide ribs 50 to move along the assembly guide grooves 51.

[0045] Furthermore, the auxiliary guide structure also includes a rotating shaft 52, a swing member 53, a fixing block 54, and a return spring 55. Each assembly guide groove 51 has a mounting through hole extending in a first direction on its bottom sidewall. The rotating shaft 52 extends in a third direction and is located within the mounting through hole. The swing member 53 is rotatably connected to the rotating shaft 52 and includes a first push rod and a second push rod. The first push rod is located on the side of the first retainer 20 away from the connecting end cover 3. The fixing block 54 is located below the first push rod and is elastically connected to the first push rod via the return spring 55. The second push rod is located within the assembly guide groove 51 and elastically abuts against the guide rib 50.

[0046] For example, in the locked state, the guide rib 50 is not fully moved within the assembly guide groove 51. The first push rod on one side of the swing member 53 abuts against the guide rib 50 and is simultaneously pressed down to its lowest point by the guide rib 50. The second push rod on the other side of the swing member 53 rises as the first push rod descends, causing the return spring 55 to stretch elastically. When moving the battery 6 in the unlocked state, the guide rib 50 moves along the assembly guide groove 51, and the second push rod moves down under the elastic contraction of the return spring 55, thereby driving the first push rod up to position and guide the battery 6. When reinstalling the battery 6 into the battery anti-dislodgement mechanism 1, the guide rib 50 moves along the assembly guide groove 51 and abuts against and presses down the first push rod, making it easier for the operator to align and position the battery 6 during installation and removal, thus improving operational convenience.

[0047] In some embodiments, reference Figures 4 to 6 The bottom of the installation channel 30 and the connecting part 41 are inclined parallel to each other in a direction away from the first end cap 60 and the end cap locking hole 32. The anti-detachment protrusion 42 is located on the side of the connecting part 41 away from the first end cap and is inclined in a direction away from the end cap locking hole 32.

[0048] For example, the bottom of the mounting channel 30 is inclined parallel to the connecting portion 41, so that when the pressing handle 4 is not rotated, the connecting portion 41 can be fixed by abutting against the connecting end cover 3. The inclined arrangement of the anti-detachment protrusion 42 can improve the stability when it abuts against the anti-detachment groove 23.

[0049] In some embodiments, reference Figures 3 to 6 The connecting end cap 3 and the first end cap are provided with multiple corresponding mounting holes 34 for fixing by bolts. The second card holder 21 is provided with a connector 26 for plugging and fixing with the battery 6. The bottom of the first card holder 20 and the bottom of the second card holder 21 are provided with slots 27 corresponding to the base plate 2 for plugging and fixing with the base plate 2.

[0050] For example, the connecting end cap 3 and the first end cap are fixed together by bolts. This bolt connection simplifies the assembly process of the connecting end cap 3 and the first end cap, improving assembly efficiency. The use of connector 26 allows it to cooperate with the first card holder 20 to fix both ends of the battery 6, and also improves the safety of connecting or disconnecting the battery 6, reducing safety hazards caused by poor contact or unstable connection. The first card holder 20 and the second card holder 21 are fixed to the base plate 2 by a mating insertion method, which enhances the overall structure's seismic resistance and improves the safety of the battery 6 during use.

[0051] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it. They cannot be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the protection scope of this utility model.
