Description

Technical Field

[0001] The utility model relates to the technical field of electric motorcycle protection, in particular to an anti-collision protection device for an electric motorcycle. Background Art

[0002] An electric motorcycle is a type of electric vehicle that uses a battery to drive an electric motor to run. The electric drive and control system consists of a drive motor, a power source, and a speed control device for the motor, etc. Other devices of the electric motorcycle are basically the same as those of an internal combustion engine. It is classified into an electric moped and an electric ordinary motorcycle according to the maximum speed or the motor power.

[0003] For the existing electric motorcycles to have a more attractive appearance, the protective structure is designed less and more concealed, so the collision protection for the vehicle body and the driver is getting weaker. The existing protective structures are designed around the vehicle body for one week along the edge of the vehicle body frame. In actual collisions, they can only provide relatively limited protection. When the vehicle falls sideways, the driver will fall to the ground from the side of the vehicle and get friction injuries, and the above-mentioned protective structures cannot play a protective role in this regard. Therefore, a new circuit board fixing structure is urgently needed to solve this problem. Summary of the Utility Model

[0004] The main purpose of the utility model is to provide an anti-collision protection device for an electric motorcycle.

[0005] The purpose of the utility model can be achieved by adopting the following technical solutions:

[0006] An anti-collision protection device for an electric motorcycle includes a side protection frame, and cross beams are detachably installed at both ends of the side protection frame;

[0007] A limiting adjustment hole penetrates through the inner wall of the side protection frame, a plugging short rod is inserted into the limiting adjustment hole, the plugging short rod is fixedly connected to a telescopic joint, and a telescopic protection rod is nested outside the telescopic joint.

[0008] Preferably, a front-end energy absorption frame welded to the side protection frame is arranged on one side below one group of the cross beams, and a first rear-end energy absorption frame welded to the side protection frame is arranged on one side below the other group of the cross beams.

[0009] Preferably, a seat protection frame is arranged directly above the cross beam, the seat protection frame is fixedly welded to the outer wall of the side protection frame through a support connecting rod, and a second rear-end energy absorption frame is welded to one side of the top of the seat protection frame.

[0010] Preferably, a rotating pin is welded to the top of the telescopic protection rod, and the rotating pin is rotationally connected in a limited way with the inner wall of the bottom end of the seat protection frame.

[0011] Preferably, a torsion spring shaft is fixed in the inner wall of the plugging short rod, a rocker is movably installed on the torsion spring shaft, and a latch capable of entering and exiting the inner wall of the plugging short rod is installed at one end of the rocker.

Detailed Embodiment

[0019] To make the technical solutions of the present utility model clearer and more definite for those skilled in the art, the present utility model will be further described in detail below in conjunction with the embodiments and the drawings. However, the embodiments of the present utility model are not limited thereto.

[0020] As Figure 1 - Figure 2As shown in the figure, an anti-collision protection device for an electric motorcycle provided in this embodiment includes a side protection frame 1, and cross beams 11 are detachably installed at both ends of the side protection frame 1; a limit adjustment hole 6 penetrates through the inner wall of the side protection frame 1, and a plug-in short rod 8 is inserted into the limit adjustment hole 6. The plug-in short rod 8 is fixedly connected to a telescopic joint 13, and a telescopic protection rod 4 is nested around the telescopic joint 13. The side anti-slip frame and its connecting components are all made of aluminum material.

[0021] On one side below one group of cross beams 11, a front-end energy-absorbing frame 2 welded to the side protection frame 1 is provided. On one side below the other group of cross beams 11, a first rear-end energy-absorbing frame 3 welded to the side protection frame 1 is provided. The first rear-end energy-absorbing frame 3 is located below the taillight and serves to protect the taillight.

[0022] Above the cross beam 11, a seat protection frame 5 is provided. The seat protection frame 5 is fixedly welded to the outer wall of the side protection frame 1 through a support connecting rod 10. On one side of the top of the seat protection frame 5, a second rear-end energy-absorbing frame 12 is welded. The second rear-end energy-absorbing frame 12 is located behind the seat protection frame 5 and serves to protect the rear seat passengers.

[0023] A rotating pin 9 is welded to the top of the telescopic protection rod 4. The rotating pin 9 is in limit rotational connection with the inner wall at the bottom end of the seat protection frame 5. The rotating pin 9 is used to support the telescopic protection rod 4 to rotate and adjust flexibly. The telescopic protection rod 4 can adjust its length through the telescopic joint 13 to realize the adjustment of the protection range for the front and rear seat passengers of the electric motorcycle.

[0024] A torsion spring shaft 15 is fixed in the inner wall of the plug-in short rod 8. A rocker 16 is movably installed on the torsion spring shaft 15. A lock catch 17 that can enter and exit the inner wall of the plug-in short rod 8 is installed at one end of the rocker 16. The plug-in short rod 8 passes through the opening of the limit adjustment hole 6, and the lock catch 17 automatically pops out to lock the plug-in short rod 8 to prevent it from withdrawing.

[0025] The other end of the rocker 16 extends into the inner wall of the telescopic joint 13 and is in contact installation with a button 14 on the outer wall of the telescopic joint 13. Four groups of mounting bolts 7 are fixed on one side of the inner wall of the side protection frame 1.

[0026] The working principle of this device:

[0027] The first step: When this device is specifically installed, the two groups of side protection frames 1 are fixed on the outer plastic shell of the electric motorcycle through the mounting bolts 7. The plastic shell is drilled for installation. Then, the front and rear cross beams 11 are inserted into the inner wall of the side protection frame 1 in the way of inner cylinder plug-in. Then, the front-end energy-absorbing frame 2, the first rear-end energy-absorbing frame 3, and the seat protection frame 5 are welded to the outer wall of the side protection frame 1;

[0028] Step 2: During use, the front-end energy-absorbing frame 2 can absorb the collision at the front end of the vehicle head, the first rear-end energy-absorbing frame 3 can absorb the collision at a lower position of the vehicle tail, and the second rear-end energy-absorbing frame 12 can absorb the collision at a higher position of the vehicle tail;

[0029] Step 3: The telescopic protective rod 4 is connected to the seat protective frame 5 through the rotating pin 9. Optionally, the plug-in short rod 8 can be inserted into the limit adjustment holes 6 on both sides of the rear seat to only protect the users on the rear seat. Also, the length of the telescopic section 13 can be extended so that the plug-in short rod 8 can be inserted into the limit adjustment holes 6 on both sides of the driver's legs to achieve the state of protecting both the driver and the personnel on the rear seat. In this way, when the vehicle rolls over or is side-collided, it is beneficial to protect the legs of the personnel and reduce the degree of injury to the personnel and damage to the vehicle.

[0030] Step 4: When the plug-in short rod 8 is inserted into the limit adjustment hole 6, the lock catch 17 is squeezed and then pops out to lock on one side of the limit adjustment hole 6 to play a locking role. When pulling it out, press the button 14, and the rocker 16 lifts the lock catch 17 to pull out the plug-in short rod 8.

[0031] The above is only a further embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the scope disclosed by the present invention, according to the technical solution and its concept of the present invention, makes equivalent substitutions or changes, all belong to the protection scope of the present invention.
