Description

Technical Field

[0001] The present invention relates to a portable vehicle, in particular to an electric scooter with a rear-view function. Background Art

[0002] An electric scooter is a vehicle based on a traditional human-powered scooter, equipped with an electric power kit. With the development of society, electric scooters have become a common means of short-distance travel, and a variety of electric scooters have emerged. For example, utility model patent publication number CN211139531U discloses an electric scooter comprising a foldable body, a steering rod, front wheels, rear wheels, a battery, a mounting platform, and a heat sink. The steering rod is located at one end of the body and is fixedly connected to the body, controlling the direction of movement. To facilitate driver control of the steering rod, a rotatably connected handle is provided on the steering rod, controlling its movement. The front wheel is located at one end of the body, on the same side as the steering rod, and is rotatably connected to the body, driving the body. The rear wheel is located at the end of the body opposite the front wheel and is rotatably connected to the body, driving the body.

[0003] When using these electric scooters, the driver's field of vision is typically focused on the front, left, and right sides, leaving a blind spot to the rear. Before changing lanes or overtaking, the driver needs to turn their head to see the road ahead, posing a significant safety hazard and requiring further improvement. Summary of the Invention

[0004] In response to the shortcomings of the existing technology, the present invention provides an electric scooter with a rear-view function. The visual receiving devices at both ends of the handlebars collect video images from behind the scooter, and upload the video images to a display module for split-screen display. The driver can directly understand the road conditions behind the scooter through the display module on the front handlebar, thereby improving driving safety.

[0005] In order to solve the above technical problems, the present invention is solved by the following technical solutions:

[0006] An electric scooter with a rearview function includes a base plate, a steering rod disposed at one end of the base plate, and a handlebar disposed transversely at the upper end of the steering rod. The midpoint of the handlebar is fixed to the upper end of the steering rod. Both ends of the handlebar are provided with a visual receiving device, which includes a housing and a high-definition camera disposed on the rear side of the housing. The high-definition cameras in the two visual receiving devices are commonly coupled to a control module, which is coupled to a display module disposed on the handlebar. The handlebar is also provided with a switch button coupled to the control module. The control module has two modes:

[0007] In the first mode, the control module controls the high-definition camera to stop and controls the display module to display the driving parameters of the electric scooter;

[0008] In the second mode, the control module activates the high-definition cameras in the two visual receiving devices to respectively capture video images behind the two ends of the handle and transmits the two sets of captured video images to the display module for split-screen display;

[0009] When the switch button responds to an external trigger, the control module can control the switching between the first mode and the second mode.

[0010] Using this solution, when the electric scooter is operating normally, the control module is in the first mode, meaning the high-definition camera is inactive and the display module on the handlebars can display the scooter's driving parameters. When the driver needs to check the road conditions behind them, they simply trigger the switch button on the handlebars to switch the control module to the second mode. The control module activates the high-definition cameras in the two visual receiving devices to capture video images behind the handlebars, respectively. These two sets of video images are then transmitted to the display module for split-screen display. This allows the driver to directly view the road conditions behind the electric scooter through the display module in front, without having to look back, thus improving driving safety. Once the rear road conditions are checked, triggering the switch button again switches the control module back to the first mode, allowing the display module to display the electric scooter's driving parameters.

[0011] Preferably, the shell is cylindrical and axially slidably connected in a sleeve, the outer wall of the sleeve is fixed to the end of the handle, and the front and rear ends of the sleeve are respectively provided with a front cover and a rear cover. The high-definition camera is arranged at the rear end of the cylindrical shell, and the rear cover is penetrated by a avoidance hole for the high-definition camera to extend out. A driving component is provided between the shell and the front cover to drive the shell to extend and retract so that the high-definition camera can protrude out of the avoidance hole or retract into the sleeve.

[0012] By adopting the above solution, the driving component can drive the shell and the high-definition camera on the shell to extend and retract, which can not only realize the video image capture of the road conditions behind the electric scooter, but also protect and prevent dust from the high-definition camera when the electric scooter is stopped or there is no need to check the road conditions behind the scooter.

[0013] Preferably, the drive assembly includes a first electromagnet and a second electromagnet respectively provided on opposite surfaces of the housing and the front cover, and an elastic member connected between the housing and the front cover to cause the housing to tend to move closer to the front cover, the first electromagnet and the second electromagnet are both coupled to and controlled by a control module;

[0014] When the control module switches to the first mode, the control module controls the first electromagnet and the second electromagnet to stop operating, so that the elastic member drives the housing close to the front cover, thereby driving the high-definition camera to retract into the sleeve;

[0015] When the control module switches to the second mode, the control module controls the operation of the first electromagnet and the second electromagnet to make the first electromagnet and the second electromagnet repel each other, thereby driving the shell to overcome the elastic force of the elastic member and move away from the front cover, thereby driving the high-definition camera to protrude out of the avoidance hole.

[0016] With this solution, when the electric scooter is stopped or the driver does not need to check the road conditions behind the scooter, the control module is placed in the first mode, which de-energizes the first and second electromagnets. This causes the elastic member to retract the housing and the HD camera on the housing into the sleeve, thereby protecting the HD camera and preventing dust. When the driver needs to check the road conditions behind the electric scooter, the control module is placed in the second mode, which controls the first and second electromagnets to repel each other, overcoming the elastic force of the elastic member and causing the housing and the HD camera on the housing to extend. This allows the HD camera to move to the outside of the rear cover to capture road conditions behind the scooter.

[0017] Preferably, the elastic member is a tension spring, and two ends of the tension spring are respectively fixed to opposite surfaces of the shell and the front cover.

[0018] By adopting the above solution, the tension spring has a simple structure, is easy to install, has low maintenance cost, and can provide a stable elastic tension to the housing to improve the driving performance and efficiency of the elastic member.

[0019] Preferably, the first electromagnet and the second electromagnet are both annular electromagnets and are concentrically arranged on opposite surfaces of the shell and the front cover, respectively. The two ends of the tension spring are respectively located in the center holes of the first electromagnet and the second electromagnet.

[0020] By adopting the above solution, the thrust and pull generated by the drive assembly can be concentrated on the center line of the shell and the front cover, further improving the driving efficiency and stability of the drive assembly.

[0021] Preferably, the outer circumference of the shell is provided with a plurality of guide strips, which are arranged along the axial direction of the shell, and the inner circumference of the sleeve is provided with a plurality of guide grooves for the guide strips to slide and engage in a one-to-one correspondence.

[0022] With the above solution, the sliding engagement between the guide bar and the guide groove can prevent the shell from rotating circumferentially in the sleeve, further improving the telescopic stability and smoothness of the shell and the high-definition camera.

[0023] Preferably, the rear end face of the housing is provided with a plurality of anti-collision bars surrounding the high-definition camera, the bars being perpendicular to the rear end face of the housing and higher than the portion of the high-definition camera protruding from the rear end face of the housing, and the rear cover is provided with a plurality of through-holes for the anti-collision bars to slide through in a one-to-one correspondence;

[0024] When the high-definition camera protrudes from the avoidance hole along with the shell, the anti-collision bar protrudes from the outer end surface of the rear cover; conversely, when the high-definition camera is retracted into the sleeve along with the shell, the anti-collision bar is synchronously retracted into the through hole.

[0025] With this solution, the anti-collision bar can extend out of the perforation with the housing to provide anti-collision protection for the HD camera on the housing. When the HD camera retracts with the housing, the anti-collision bar can also retract into the perforation to reduce the occupied space.

[0026] Preferably, the inner circumference of the sleeve is provided with a plurality of avoidance grooves for sliding and engaging the plurality of anti-collision bars in a one-to-one corresponding manner.

[0027] By adopting the above solution, the avoidance groove can provide avoidance space for the retraction of the anti-collision bar, preventing the shell and the high-definition camera from being obstructed during the retraction process.

[0028] Due to the adoption of the above technical solution, the present invention has significant technical effects: when the electric scooter is running normally, the control module is in the first mode, that is, the high-definition camera is in the shutdown state and the display module on the handle can display the driving parameters of the scooter. When the driver needs to check the road conditions behind, he only needs to trigger the switch button on the handle to switch the control module to the second mode, that is, the control module starts the high-definition cameras in the two visual receiving devices to respectively collect video images behind the two ends of the handle and transmit the two sets of collected video images to the display module for split-screen display, so that the driver can directly understand the road conditions behind the electric scooter through the front display module without having to turn his head to look back, thereby improving driving safety. After the rear road conditions are checked, the switch button is triggered again to switch the control module back to the first mode so that the display module can display the driving parameters of the electric scooter.

[0037] The present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0038] like Figure 1 、 Figure 2 and Figure 3 As shown, the present embodiment discloses an electric scooter with a rearview function, comprising a base plate 1, a steering rod 2 provided at one end of the base plate 1, and a handle 3 laterally provided at the upper end of the steering rod 2. The midpoint of the handle 3 is fixed to the upper end of the steering rod 2, and visual receiving devices 4 are provided at both ends of the handle 3. Specifically, the visual receiving device 4 comprises a shell 5 and a high-definition camera 6 provided on the rear side of the shell 5. The high-definition cameras 6 in the two visual receiving devices 4 are commonly coupled to a control module 7, and the control module 7 is preferably a single-chip microcomputer. The control module 7 is coupled to a display module 8 provided on the handle 3, and the display module 8 is preferably a display screen or a touch screen. In this embodiment, the control module 7 has two modes:

[0039] In the first mode, the control module 7 controls the high-definition camera 6 to stop and controls the display module 8 to display the driving parameters of the electric scooter, including but not limited to the current driving speed, output power, remaining power, mileage, etc. of the electric scooter.

[0040] In the second mode, the control module 7 activates the high-definition cameras 6 in the two visual receiving devices 4 to respectively capture video images behind the two ends of the handle 3 and transmits the two sets of captured video images to the display module 8 for split-screen display, thereby allowing the driver to directly view the road conditions behind the electric scooter through the front display module 8 without having to turn his head to look back, thereby improving driving safety.

[0041] like Figure 4 As shown, in order to achieve rapid switching between the first mode and the second mode, a switching button 9 coupled to the control module 7 is also provided on the handle 3. When the switching button 9 responds to an external trigger, the control module 7 can control the mutual switching between the first mode and the second mode to improve operational efficiency and convenience.

[0042] like Figure 3 and Figure 5 As shown, to protect and dustproof the HD camera 6, the housing 5 is cylindrical and axially slidably connected within a cylindrical sleeve 10. The outer wall of the sleeve 10 is fixed to the end of the handle 3. The front and rear ends of the sleeve 10 are respectively provided with a front cover 11 and a rear cover 12. Both the front cover 11 and the rear cover 12 are circular to accommodate the shape of the end of the sleeve 10. The HD camera 6 is mounted at the rear end of the cylindrical housing 5. The rear cover 12 is penetrated by a clearance hole 13 for the HD camera 6 to extend. A drive assembly is located between the housing 5 and the front cover 11, which drives the housing 5 to extend and retract, allowing the HD camera 6 to extend out of the clearance hole 13 or retract into the sleeve 10. Specifically, the drive assembly includes a first electromagnet 14 and a second electromagnet 15, respectively disposed on opposing surfaces of the housing 5 and the front cover 11, and an elastic member 16 connected between the housing 5 and the front cover 11 to force the housing 5 toward the front cover 11. The elastic member 16 is a tension spring, the two ends of which are welded and fixed to the opposite surfaces of the housing 5 and the front cover 11, respectively. The first electromagnet 14 and the second electromagnet 15 are both coupled and controlled by the control module 7. In this embodiment, when the control module 7 switches to the first mode, the control module 7 controls the first electromagnet 14 and the second electromagnet 15 to stop operating, so that the elastic member 16 drives the housing 5 closer to the front cover 11, thereby driving the high-definition camera 6 to retract into the sleeve 10, thereby protecting the high-definition camera 6 and preventing dust. Conversely, when the control module 7 switches to the second mode, the control module 7 controls the first electromagnet 14 and the second electromagnet 15 to operate, so that the first electromagnet 14 and the second electromagnet 15 repel each other, thereby driving the housing 5 away from the front cover 11 to overcome the elastic force of the elastic member 16, thereby driving the high-definition camera 6 to protrude out of the avoidance hole 13, facilitating the visual receiving device 4 to capture video images from the rear of the electric scooter.

[0043] like Figure 5 and Figure 6 As shown, in order to improve the driving efficiency and stability of the driving component, the first electromagnet 14 and the second electromagnet 15 are both annular electromagnets and are concentrically arranged on the opposite surfaces of the shell 5 and the front cover 11, and the two ends of the tension spring are respectively located in the center holes of the first electromagnet 14 and the second electromagnet 15.

[0044] like Figure 6 As shown, in order to improve the telescopic stability and smoothness of the high-definition camera 6, two guide bars 17 are provided on the outer circumference of the shell 5. The guide bars 17 are arranged along the axial direction of the shell 5, and the inner circumference of the sleeve 10 is provided with two guide grooves 18 for the two guide bars 17 to slide and engage in a one-to-one manner.

[0045] like Figure 5 、 Figure 6 and Figure 7As shown, in order to provide anti-collision protection for the high-definition camera 6 that protrudes out of the avoidance hole 13, twelve anti-collision bars 19 surrounding the high-definition camera 6 are arranged at equal intervals on the rear end face of the shell 5. The rod body of each anti-collision bar 19 is perpendicular to the rear end face of the shell 5 and is higher than the part of the high-definition camera 6 that protrudes out of the rear end face of the shell 5. Twelve through-holes 20 are provided on the rear cover 12 for the twelve anti-collision bars 19 to slide through in a one-to-one correspondence. In this embodiment, when the high-definition camera 6 protrudes out of the avoidance hole 13 with the shell 5, the anti-collision bar 19 protrudes from the outer end face of the rear cover 12, which can not only provide anti-collision protection for the high-definition camera 6, but also prevent the image acquisition work of the high-definition camera 6 from being affected. Conversely, when the high-definition camera 6 is retracted into the sleeve 10 with the shell 5, the anti-collision bar 19 is simultaneously retracted into the through-hole 20 to reduce the space occupied by the anti-collision bar 19 and at the same time be more beautiful.

[0046] like Figure 7 As shown, in order to allow the anti-collision rods 19 to retract smoothly, the inner circumference of the sleeve 10 is provided with twelve avoidance grooves 21 for the twelve anti-collision rods 19 to slide and engage in a one-to-one corresponding manner.

[0047] The specific usage process is as follows:

[0048] When the electric scooter is in normal operation, the control module 7 is placed in the first mode. At this point, the control module 7 controls the display module 8 to display the electric scooter's operating parameters, making it easier for the driver to check the operating status. Simultaneously, the control module 7 de-energizes the first and second electromagnets 14 and 15. This allows the housing 5 and the HD camera 6 located thereon to approach the front cover 11 under the elastic force of the elastic member 16, thereby causing the HD camera 6 and the anti-collision bar 19 to retract. This not only protects the HD camera 6 and prevents dust, but also reduces the space occupied by the anti-collision bar 19. Simultaneously, the control module 7 shuts down the HD camera 6 to conserve energy.

[0049] When the electric scooter is in a stopped state, the control module 7 can turn off the display module 8 in the first mode to further save power.

[0050] When the driver needs to check the road conditions behind the electric scooter, they simply trigger the switch button 9 on the front handle 3 to place the control module 7 in the second mode. In the second mode, the control module 7 synchronously controls the operation of the first electromagnet 14 and the second electromagnet 15 in the two visual receiving devices 4 to generate a repulsive force between them, thereby driving the housing 5 and the high-definition camera 6 on the housing 5 to extend backward, overcoming the elastic force of the elastic member 16, until the high-definition camera 6 protrudes out of the avoidance hole 13. At the same time, the control module 7 controls the operation of the high-definition cameras 6 in the two visual receiving devices 4 to respectively capture video images behind the two ends of the handle 3 and transmit the two sets of captured video images to the display module 8 for split-screen display. This allows the driver to directly view the road conditions on both sides of the rear of the electric scooter through the front display module 8 without having to turn their head to look back, thereby improving driving safety. At the same time, the anti-collision bar 19 extends through the perforation 20 along with the housing 5 to provide anti-collision protection for the high-definition camera 6. When the driver has finished checking the road conditions behind, the driver can trigger the switch button 9 again to put the control module 7 into the first mode again, so that the display module 8 will display the driving parameters again.

[0051] The above control process can be implemented with the help of the built-in control program of the control module 7, which is common knowledge in the field and will not be described in detail here.
