[0040] Furthermore, terms such as "identical" do not imply that components must be absolutely identical; minor differences are permissible. The term "perpendicular" simply means that the positional relationship between components is more perpendicular than "parallel," not that the structure must be perfectly perpendicular; a slight tilt is acceptable.

[0041] Please see Figure 1-11 This utility model provides a technical solution: an electric motorcycle collision and rollover protection device, including a mounting box, a first rod 1, a second rod 2, a connector, and a drive unit. The first rod 1, the second rod 2, and the connector are all made of conductive material. Specifically, the first rod 1, the second rod 2, and the connector can all be made of copper. The inner ends of the first rod 1, the second rod 2, and the connector are all located inside the mounting box, while the outer ends of the first rod 1 and the second rod 2 are located outside the mounting box. The inner ends of the first rod 1 and the second rod 2 abut against the connector, that is, one end of the first rod 1 inside the mounting box and one end of the second rod 2 inside the mounting box abut against the connector. The drive unit is used to drive the connector to disengage from the first rod 1 and the second rod 2 when the electric motorcycle rolls over.

[0042] When using the electric motorcycle collision and rollover protection device described in this utility model, the mounting box is glued and fixed to the electric motorcycle with strong adhesive. The first rod 1 is connected to the positive terminal of the electric motorcycle battery through a wire, and the second rod 2 is connected to the positive terminal of the electrical equipment on the electric motorcycle through a wire, so that the electric motorcycle collision and rollover protection device described in this utility model is connected in series in the power supply circuit of the electrical equipment on the electric motorcycle.

[0043] During normal operation of the electric motorcycle, the inner ends of the first rod 1 and the second rod 2 are both in contact with the connector, and the positive terminal of the battery can be kept connected to the positive terminal of the electrical equipment on the electric motorcycle.

[0044] After the electric motorcycle is hit and overturns, the drive unit drive connector disengages from the first rod 1 and the second rod 2. At this time, the positive terminal of the battery and the positive terminal of the electrical equipment on the electric motorcycle are disconnected, which can reduce the possibility of the battery continuing to supply power and reduce the risk of short circuit.

[0045] In this embodiment, the first rod 1 and the second rod 2 are respectively disposed on the front and rear side walls of the mounting box, and both the first rod 1 and the second rod 2 are arranged in the front-rear direction;

[0046] It also includes a rotating component that is rotatably connected to the mounting box, wherein the rotation center line of the rotating component is arranged in the front-back direction;

[0047] The connector includes a first contact 3, a second contact 4, and a connecting wire 5. The first contact 3, the second contact 4, and the connecting wire 5 are all made of conductive material. Specifically, the first contact 3, the second contact 4, and the connecting wire 5 can all be made of copper. The first contact 3 and the second contact 4 are spaced apart and are offset from the rotation center line of the rotating component. The first contact 3 abuts against the rear end of the first rod 1, and the second contact 4 abuts against the front end of the second rod 2. The two ends of the connecting wire 5 are fixedly connected to the first contact 3 and the second contact 4, respectively. The driving part is used to drive the rotating component to rotate when the electric motorcycle flips over, so that the first contact 3 and the second contact 4 are respectively disengaged from the first rod 1 and the second rod 2.

[0048] Since the first rod 1 and the second rod 2 are respectively located on the front and rear side walls of the mounting box, and both the first rod 1 and the second rod 2 are arranged in the front-rear direction, the rear end of the first rod 1 is located inside the mounting box, and the front end of the second rod 2 is located inside the mounting box.

[0049] During normal operation of the electric motorcycle, the first contact block 3 abuts against the rear end of the first rod 1, and the second contact block 4 abuts against the front end of the second rod 2. At this time, the inner end of the first rod 1 and the inner end of the second rod 2 can both abut against the connecting piece.

[0050] When an electric motorcycle is impacted and overturns, the drive unit drives the rotating component to rotate. Since both the first contact block 3 and the second contact block 4 are offset from the rotation center line of the rotating component, during the rotation process, the rotating component can cause the first contact block 3 and the second contact block 4 to move in a circle around the rotation center line. After the rotating component rotates a certain angle, the first contact block 3 and the second contact block 4 can disengage from the first rod 1 and the second rod 2, respectively. With this structure, the drive unit can drive the connecting component to disengage from the first rod 1 and the second rod 2 when the electric motorcycle overturns.

[0051] In this embodiment, a protruding plate 6 is formed on the bottom plate of the mounting box, and a shaft 7 is fixed on the protruding plate 6. The shaft 7 is arranged in the front-back direction.

[0052] The rotating component includes a first vertical plate 8, a second vertical plate 9, and a horizontal plate 10. The first vertical plate 8 and the second vertical plate 9 respectively abut against the front and rear sides of the convex plate 6. Both the first vertical plate 8 and the second vertical plate 9 have shaft holes, and both shaft holes are rotatably fitted onto the shaft 7.

[0053] Since both shaft holes are rotatably fitted onto the shaft 7, both the first vertical plate 8 and the second vertical plate 9 can rotate on the shaft 7. The first vertical plate 8 and the second vertical plate 9 are rotatably connected to the mounting box via the shaft 7 and the protruding plate 6. The rotating component is thus rotatably connected to the mounting box.

[0054] In this embodiment, the first contact block 3 is fixed to the front side of the first vertical plate 8, and the second contact block 4 is fixed to the rear side of the second vertical plate 9. Both the first contact block 3 and the second contact block 4 are offset from the shaft 7. The axis of the shaft 7 is the rotation center line of the rotating component. Since both the first contact block 3 and the second contact block 4 are offset from the shaft 7, they can thus be offset from the rotation center line of the rotating component.

[0055] In this embodiment, the driving unit includes a vertical rod 11 and two counterweight rods 12. The vertical rod 11 and the two counterweight rods 12 are all located inside the mounting box. The vertical rod 11 is fixed on the rotating member. The axis of the vertical rod 11 intersects perpendicularly with the rotation center line of the rotating member. The two counterweight rods 12 are arranged in the front-back direction. The two counterweight rods 12 respectively abut against the left and right sides of the vertical rod 11. The counterweight rod 12 on the left side of the vertical rod 11 is connected to the mounting box in a way that it can slide to the upper left. The counterweight rod 12 on the right side of the vertical rod 11 is connected to the mounting box in a way that it can slide to the upper right.

[0056] When the mounting box is installed on the electric motorcycle, the electric motorcycle is in an upright position, the bottom plate of the mounting box is in a nearly horizontal position, and the vertical rod 11 is in a nearly upright position.

[0057] When the electric motorcycle is in normal driving mode, it is in a nearly upright position, and the base plate of the mounting box is nearly horizontal. At this time, the vertical rod 11 is also nearly upright, and the two counterweight rods 12 respectively abut against the left and right sides of the vertical rod 11. Under their own weight, the two counterweight rods 12 clamp the vertical rod 11, preventing it from swinging left or right, and thus preventing the rotating component from rotating. At this time, the first contact block 3 remains abutting against the rear end of the first rod body 1, and the second contact block 4 remains abutting against the front end of the second rod body 2. Furthermore, the sliding path of the counterweight rod 12 on the left side of the vertical rod 11 is inclined to the upper left, and the sliding path of the counterweight rod 12 on the right side of the vertical rod 11 is inclined to the upper right.

[0058] When an electric motorcycle overturns, there are two possibilities: it may overturn to the left or to the right.

[0059] After the electric motorcycle flips to the left, the sliding path of the counterweight rod 12 on the left side of the vertical rod 11 can be changed to a state of tilting to the lower left. At this time, the counterweight rod 12 on the left side of the vertical rod 11 will slide to the lower left, and the vertical rod 11 will swing to the lower left under its own gravity and drive the rotating component to rotate.

[0060] After the electric motorcycle flips to the right, the sliding path of the counterweight rod 12 on the right side of the vertical rod 11 can be changed to a state of tilting to the lower right. At this time, the counterweight rod 12 on the right side of the vertical rod 11 will slide to the lower right, and the vertical rod 11 will swing to the lower right under its own gravity and drive the rotating component to rotate.

[0061] With this structure, the drive unit can drive the rotating component to rotate when the electric motorcycle overturns.

[0062] In this embodiment, the rear side of the front sidewall of the mounting box is recessed to form two first sliding grooves 13. The two first sliding grooves 13 are arranged symmetrically and form an upwardly opening figure-eight structure. A first slider 14 is slidably engaged in both first sliding grooves 13.

[0063] The front side of the rear sidewall of the mounting box is recessed to form two second sliding grooves 15. The projections of the two second sliding grooves 15 on the rear side of the front sidewall of the mounting box correspond one-to-one with the two first sliding grooves 13. A second slider 16 is slidably engaged in both second sliding grooves 15.

[0064] The front ends of the two counterweight rods 12 are fixedly connected to the two first sliders 14 in a one-to-one correspondence, and the rear ends of the two counterweight rods 12 are fixedly connected to the two second sliders 16 in a one-to-one correspondence.

[0065] The first slider 14, located to the left of the centerline of the vertical rod 11, can slide upward and to the left within the first groove 13 located to the left of the centerline of the vertical rod 11. The second slider 16, located to the left of the centerline of the vertical rod 11, can slide upward and to the left within the second groove 15 located to the left of the centerline of the vertical rod 11. The first slider 14, located to the right of the centerline of the vertical rod 11, can slide upward and to the right within the first groove 13 located to the right of the centerline of the vertical rod 11. The second slider 16, located to the right of the centerline of the vertical rod 11, can slide upward and to the right within the second groove 15 located to the right of the centerline of the vertical rod 11. Since the front ends of the two counterweight rods 12 are fixedly connected to the two first sliders 14 one-to-one, and the rear ends of the two counterweight rods 12 are fixedly connected to the two second sliders 16 one-to-one, the counterweight rod 12 on the left side of the vertical rod 11 can thus be connected to the mounting box in a manner that allows it to slide upward and to the left, and the counterweight rod 12 on the right side of the vertical rod 11 can thus be connected to the mounting box in a manner that allows it to slide upward and to the right.

[0066] In this embodiment, the first rod 1 is slidably disposed on the front side wall of the mounting box, and the second rod 2 is slidably disposed on the rear side wall of the mounting box.

[0067] It also includes a first rubber sleeve 17 and a second rubber sleeve 18. Both the first rubber sleeve 17 and the second rubber sleeve 18 are cylindrical. The first rubber sleeve 17 is sleeved on the first rod body 1. The front end of the first rubber sleeve 17 abuts against the front side wall of the mounting box and the rear end is fixedly connected to the first rod body 1. The first rubber sleeve 17 is in a compressed state. The second rubber sleeve 18 is sleeved on the second rod body 2. The rear end of the second rubber sleeve 18 abuts against the rear side wall of the mounting box and the front end is fixedly connected to the second rod body 2. The second rubber sleeve 18 is in a compressed state.

[0068] The rubber sleeves are elastic. When the electric motorcycle is running normally, both the first rubber sleeve 17 and the second rubber sleeve 18 are in a compressed state. The first rubber sleeve 17 provides a backward elastic thrust to the first rod 1, so that the rear end of the first rod 1 can hold the first contact block 3 more tightly. The second rubber sleeve 18 provides a forward elastic thrust to the second rod 2, so that the front end of the second rod 2 can hold the second contact block 4 more tightly.

[0069] In this embodiment, a first fixing part and a second fixing part are also included. The first fixing part is disposed at the front end of the first rod 1 and is used to fix the wire to the first rod 1. The second fixing part is disposed at the rear end of the second rod 2 and is used to fix the wire to the second rod 2.

[0070] When connecting the wire to the first rod 1, the wire is specifically fixed to the first rod 1 through the first fixing part; when connecting the wire to the second rod 2, the wire is specifically fixed to the second rod 2 through the second fixing part.

[0071] In this embodiment, the first fixing part includes a first baffle 19, a first screw 20, and a first nut 21. The first baffle 19 and the first screw 20 are both made of conductive material. Specifically, the first baffle 19 and the first screw 20 can be made of copper. The first baffle 19 is fixed to the front end of the first rod 1, the first screw 20 is fixed to the middle of the front side of the first baffle 19, and the first nut 21 is screwed onto the first screw 20.

[0072] The second fixing part includes a second baffle 22, a second screw 23 and a second nut 24. The second baffle 22 and the second screw 23 are both made of conductive material. Specifically, the second baffle 22 and the second screw 23 can be made of copper. The second baffle 22 is fixed to the rear end of the second rod body 2, the second screw 23 is fixed to the middle of the rear side of the second baffle 22, and the second nut 24 is screwed onto the second screw 23.

[0073] When connecting the wire to the first rod 1, the wire core is wound around the first screw 20 and brought into contact with the first baffle 19. Then, the first nut 21 is rotated on the first screw 20, causing the first nut 21 to move backward on the first screw 20. After the first nut 21 moves backward a certain distance, the first nut 21 and the first baffle 19 can clamp the wire core in the middle. At this time, the wire can be fixedly connected to the first rod 1. The first fixing part can thus fix the wire to the first rod 1.

[0074] When connecting the wire to the second rod 2, the wire core is wound around the second screw 23 and brought into contact with the second baffle 22. Then, the second nut 24 is rotated on the second screw 23, causing the second nut 24 to move forward on the second screw 23. After the second nut 24 moves forward a certain distance, the second nut 24 and the second baffle 22 can clamp the wire core in the middle. At this time, the wire can be fixedly connected to the second rod 2, and the second fixing part can thus fix the wire to the second rod 2.

[0075] In this embodiment, the mounting box includes a box body 25 and a box cover 26. The upper end of the box body 25 is open, and the box cover 26 is detachably and fixedly connected to the box body 25, and the box cover 26 closes the upper end of the box body 25.

[0076] When the electric motorcycle collision and rollover protection device described in this utility model is used normally, the cover 26 is fixed on the box body 25 and closes the opening at the upper end of the box body 25. The inner end of the first rod 1, the inner end of the second rod 2, the rotating part, the connecting part and the driving part are all located in the mounting box and are protected by the mounting box.

[0077] After the electric motorcycle overturns and is then righted to an upright position, the cover 26 can be removed from the housing 25. Then, the two counterweights 12 can be moved inside the housing 25, and the vertical rod 11 and the rotating component can be rotated inside the housing 25 to restore the first contact block 3 to the state of abutting the rear end of the first rod 1, and to restore the second contact block 4 to the state of abutting the front end of the second rod 2.

[0078] In this embodiment, the upper end of the side wall of the box body 25 is recessed downward to form multiple screw holes. A through hole is formed on the box cover 26 corresponding to each screw hole, and a bolt 27 is provided in each through hole. The bolt 27 is screwed into the corresponding screw hole, and the bolt head of the bolt 27 abuts against the upper side of the box cover 26 downward. With this structure, the box cover 26 is specifically detachably fixed to the box body 25 by bolts 27.

[0079] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it.
