Description

Multi-directionally adjustable electric bicycle and its sharing device

This application is related to electric bicycles, and in particular to a multi-directionally adjustable electric bicycle and its shared equipment.

The electric bicycle is equipped with a vehicle battery on the frame, and the vehicle battery is used to supply power to the wheel motor, so that the wheel motor can drive the wheel to rotate, thereby driving the entire electric bicycle to move forward. Among them, the frame has a front fork sleeve.

However, even for electric bicycles, the handlebars are fixed on a rod assembly, and the rod assembly is inserted into the front fork sleeve, and a screw element or a buckle is used to tightly fix the rod assembly to the front fork sleeve, so that the rod assembly cannot expand or contract relative to the front fork sleeve. As a result, some users with less strength (such as children or female users) find it difficult to loosen the screw element or unlock the buckle, and thus cannot adjust the height of the handlebars. Therefore, it is often seen that these users ask passers-by on the roadside to help loosen the screw element or unlock the buckle; even the handlebars cannot move forward or backward relative to the front fork sleeve. All of these cause inconvenience to users and have long been criticized.

Therefore, how to design an application that can improve the above-mentioned deficiencies is a major issue that the creator of this application is eager to solve.

The purpose of this application is to provide a multi-directionally adjustable electric bicycle and its shared equipment, by which the multi-directional adjustment device is powered by the on-board battery originally possessed by the electric bicycle, so that the height and front and rear position of the handlebars can be driven and adjusted.

In order to achieve the above-mentioned object, the present application provides a multi-directionally adjustable electric bicycle, which is equipped with an on-board battery and includes: a handlebar; a frame, including a front fork sleeve, a rod assembly rotatably inserted in the front fork sleeve, and one end of the rod assembly is arranged on the handlebar; and a multi-directional adjustment device, connected to the on-board battery and including: a lifting actuator, which is arranged in the front fork sleeve and has a driving rod, and the driving rod is connected to the rod assembly. the other end; a front-rear driver, which is arranged on the handle and has a driving rod, and the driving rod is fixed to the one end of the rod assembly; and a controller, which is connected to and controls the lifting driver and the front-rear driver, the controller controls the lifting driver to drive the rod assembly together with the handle to extend and retract relative to the front fork sleeve with the driving rod, and the controller controls the front-rear driver to drive the handle to move forward and backward relative to the front fork sleeve with the driving rod.

In order to achieve the above-mentioned purpose, the present application also provides a sharing device for electric bicycles, comprising: at least one docking station, which is electrically connected to an external power source and has a connecting portion; and at least one electric bicycle that can be adjusted in multiple directions as described above, which can be detachably connected to the connecting portion and electrically connected to each other, and the external power source supplies power to the multi-directional adjustment device and the vehicle battery via the docking station.

Compared with the prior art, the present application has the following effects: the multi-directional adjustment device can be powered by the vehicle battery of the electric bicycle, and the height and front and rear position of the handlebars can be adjusted by the lifting drive and the front and rear drives, so even users with less strength can easily adjust the handlebars.

The detailed description and technical contents of this application are described below with the help of drawings. However, the attached drawings are only provided for reference and description and are not used to limit this application.

The present application provides a multi-directionally adjustable electric bicycle and a shared device thereof. As shown in Figures 1, 2 and 5, they are a first embodiment of the multi-directionally adjustable electric bicycle (hereinafter referred to as the electric bicycle) of the present application, as shown in Figures 3 to 4, they are a second embodiment of the electric bicycle of the present application, and as shown in Figure 6, it is a shared device of the electric bicycle of the present application (hereinafter referred to as the shared device).

As shown in FIG. 1 , FIG. 2 and FIG. 5 , the first embodiment of the electric bicycle of the present application is equipped with a vehicle-mounted battery B. The electric bicycle includes: a frame 1, a seat pad 3, a handlebar 4, a multi-directional adjustment device 5 and two wheels (component symbols are not indicated). Among them, the vehicle-mounted battery B is arranged on the frame 1. The original purpose of the vehicle-mounted battery B is to supply power to the wheel motor (not shown in the figure), so that the wheel motor can drive the wheel, thereby driving the entire electric bicycle to move.

The frame 1 mainly includes a seat rod 11 and a front fork sleeve 12. A rod assembly 121 is rotatably inserted into the front fork sleeve 12. The handle 4 is arranged at the upper end of the rod assembly 121.

The multi-directional adjustment device 5 is connected to the vehicle battery B, so that the vehicle battery B can also supply power to the multi-directional adjustment device 5. In other words, the vehicle battery B of the electric bicycle of the present application can supply power to both the wheel motor and the multi-directional adjustment device 5. The multi-directional adjustment device 5 includes: a lifting actuator 51b, a front and rear actuator 56b and a controller 531. The lifting actuator 51b and the front and rear actuator 56b can be any machine that can drive an object to move, such as: a pneumatic linear actuator, a hydraulic linear actuator or a motor.

In this embodiment, the lifting actuator 51b is described by taking a pneumatic/hydraulic (air pressure or oil pressure) linear actuator as an example. The pneumatic/hydraulic linear actuator mainly uses a pneumatic pump or a hydraulic pump for linear driving.

The lifting actuator 51 b is disposed in the front fork sleeve 12 and has a driving rod 511 , and the driving rod 511 is connected to the lower end of the rod assembly 121 .

The front and rear actuator 56 b is disposed on the handle 4 and has a driving rod 562 . The driving rod 562 is fixed to the upper end of the rod assembly 121 .

The controller 531 may be, for example, a microprocessor or a processing unit, and the present application is not limited thereto. The lifting actuator 51b and the front-rear actuator 56b are both connected to the controller 531, so that the controller 531 can control the linear movement of the driving rod 511 of the lifting actuator 51b, and can also control the linear movement of the driving rod 562 of the front-rear actuator 56b.

2 and 5 , the controller 531 can be used to control the linear movement of the driving rod 511 of the lifting actuator 51b, and the driving rod 511 can drive the rod assembly 121 together with the handle 4 to extend and retract relative to the front fork sleeve 12 through the linear movement; the controller 531 can also be used to control the front and rear actuator 56b to drive the rod body 562 to push and pull the rod assembly 121 and thereby drive the handle 4 to move forward and backward relative to the front fork sleeve 12 in the opposite direction. In this way, the purpose of adjusting the height and the front-and-rear position of the handlebar 4 in multiple directions is achieved, and the multi-directional adjustment device 5 is powered by the existing (originally possessed) on-board battery B of the electric bicycle, so that the height of the handlebar 4 can be adjusted by the lifting actuator 51b (not by human power) and the front-and-rear position of the handlebar 4 can be driven by the front-and-rear actuator 56b (not by human power). Therefore, even users with less strength can easily adjust the height of the handlebar 4.

In order to facilitate manual adjustment by the user, as shown in Figures 1, 2 and 5, the multi-directional adjustment device 5 also includes a control terminal 54. The control terminal 54 can be a control panel or a control instrument panel, and this application does not limit this, as long as it can be controlled by the user. The control terminal 54 is electrically connected to the controller 531 and is configured with at least one button 541 (a physical button or a touchable virtual button), so that the user can control the lifting actuator 51b and the front and rear actuator 56b by pressing the button 541, thereby achieving the purpose of manually adjusting the height and front and rear position of the handle 4 proximally. It should be noted that the control terminal 54 can be set on the frame 1 (not shown in the figure) or on the handle 4 (as shown in Figures 1 and 2).

The multi-directional adjustment device 5 may also have a memory function. As shown in FIG. 2 and FIG. 5 , the multi-directional adjustment device 5 further includes a control device 53, which is disposed on the frame 1 and includes a memory unit 532 and the aforementioned controller 531. The memory unit 532 is electrically connected to the controller 531, and the aforementioned button 541 is electrically connected to the memory unit (not shown in the figure) to form a so-called memory button. In other embodiments not shown in the figure, the control device 53 may also be disposed on the handle 4.

Thus, after adjusting the height and fore-and-aft position of the handle 4, the user only needs to press the button 541 to store the height position data (e.g., the height position data of the handle 4 relative to the frame 1) and the fore-and-aft position data of the handle 4 that have been adjusted at this time in the memory unit 532. Thereafter, the user can press the button 541 again at any time to allow the controller 531 to control the lifting actuator 51b and the fore-and-aft actuator 56b to automatically adjust the height and fore-and-aft position of the handle 4 according to the height position data and fore-and-aft position data stored in the memory unit 532, so that the adjusted height and fore-and-aft position of the handle 4 can be adapted to the user. Of course, the number of buttons (memory buttons) 541 can be plural (at least two), and the memory unit 532 stores plural high and low position data and plural front and rear position data, thereby allowing plural users to share the same electric bicycle.

The multi-directional adjustment device 5 may also have the function of allowing the user to input personal body data. As shown in FIG2 and FIG5 , the electric bicycle of the present application may store a plurality of preset control data (e.g., data on how much driving stroke the driving rod 511 and the driving rod body 562 should perform) in the memory unit 532, and these preset control data also correspond to a plurality of body data ranges.

Thus, the user only needs to input his/her personal body data (e.g., height, leg length, and arm length, etc.) on the control terminal 54, and the controller 531 will start to compare the personal body data input by the user with all the aforementioned body data ranges. Assuming that the personal body data falls within the range of the Xth body data (e.g., the personal body data is 175 cm in height, which falls within the body data range of 170 to 180 cm in height), the controller 531 will control the lifting actuator 51b and the front and rear actuator 56b to automatically adjust the height and the front and rear position of the handle 4 according to the preset control data corresponding to the Xth body data range.

The multi-directional adjustment device 5 may also have a remote control function. As shown in FIG2 and FIG5, the electric bicycle of the present application further includes a remote control device 6, and the control device 53 further includes a wireless transmission unit 533, and the wireless transmission unit 533 is electrically connected to the controller 531. The remote control device 6 may be, for example, a smart phone, a tablet computer or a similar electronic product, and the present application does not limit this.

Thus, the user only needs to operate the remote control device 6 remotely, and the remote control device 6 will wirelessly send a data or a signal. After the wireless transmission unit 533 in the multi-directional adjustment device 5 receives the data or signal, the controller 531 will control the lifting actuator 51b and the front and rear actuator 56b to adjust the height and the front and rear position of the handle 4 respectively according to the data or signal.

For example, a parent uses the remote control device 6 at work to input the child's personal body data remotely, and wirelessly sends the child's personal body data to the electric bicycle parked at home through the remote control device 6, and allows the wireless transmission unit 533 on the vehicle to receive the child's personal body data. The controller 531 compares and finds that the received personal body data falls within the range of the Yth body data. The controller 531 controls the lifting actuator 51b and the front and rear actuator 56b to automatically adjust the height and front and rear position of the handle 4 according to the preset control data corresponding to the range of the Yth body data. Of course, the user may also send a signal (such as a control signal) via the remote control device 6, and the controller 531 directly controls the actions of the lifting actuator 51b and the front and rear actuator 56b according to the signal.

The multi-directional adjustment device 5 may also have an image recognition function. As shown in FIG2 and FIG5 , the multi-directional adjustment device 5 further includes an image recognizer 55, and the image recognizer 55 is electrically connected to the controller 531. The image recognizer 55 may be any electronic product capable of image recognition, which can capture the image of the user with a lens (such as a smart lens, etc.) and recognize the user's personal body data with the image.

Thus, any user can perform image recognition and identify his/her personal body data as long as he/she stands in front of the image recognition device 55. The controller 531 determines through comparison that the identified personal body data falls within the range of the Zth body data, for example. The controller 531 controls the lifting actuator 51b and the front and rear actuator 56b to automatically adjust the height and the front and rear position of the handle 4 according to the preset control data corresponding to the Zth body data range.

As shown in FIG. 3 and FIG. 4, the second embodiment of the electric bicycle of the present application is substantially the same as the first embodiment, and the difference is only that the lifting actuator 52b used is different from that of the first embodiment. The second embodiment can also achieve all the effects of the first embodiment.

The lifting driver 52b used in the second embodiment is a motor, and the driving rod 521 of the motor can be a screw as shown in the figure, which is screwed to the lower end of the rod assembly 121; or, in other embodiments not shown in the figure, the driving rod 521 of the motor can also be a rotating shaft provided with a gear, the gear is connected to a toothed bar, and the toothed bar is connected to the lower end of the rod assembly 121.

FIG6 is a side view of the shared device of the present application, in which the electric bicycle of the first embodiment is used as an example for sharing, but in practice, the electric bicycle of the second embodiment can also be used for sharing. The shared device of the present application includes: a plurality of parking posts 9 and a plurality of electric bicycles as described above.

The parking post 9 is used for parking the electric bicycle and has a connecting portion 91. An external power source (not shown) is connected to the parking post 9, and the connecting portion 91 is electrically connected to the external power source.

The aforementioned electric bicycle can be detachably connected to the assembly part 91 to electrically dock with each other, so that the electric bicycle can be parked, and an external power source can supply power to the multi-directional adjustment device 5 through the parking pole 9, and can even supply power to the vehicle battery B or charge the vehicle battery B.

The shared device of this application can also be adjusted in multiple directions by swiping a card. As shown in Figures 5 and 6, the shared device also includes a borrowing/returning card (not shown in the figure), and the borrowing/returning card stores personal body data.

Thus, when the user wants to borrow a car and adjust the height and front-back position of the handle 4, he only needs to swipe the borrowing/returning card to the parking pile 9 to borrow the car, and the personal body data stored in the card can be transmitted to the controller 531 through the parking pile 9. The controller 531 compares and finds that the personal body data from the borrowing/returning card falls within the range of the Mth body data. The controller 531 controls the lifting actuator 51b and the front-back actuator 56b to automatically adjust the height and the front-back position of the handle 4 according to the preset control data corresponding to the Mth body data range. In short, the user only needs to swipe the card to borrow the car, and the height and the front-back position of the handle 4 can be automatically adjusted.

Of course, the user can also return the vehicle by swiping a card, so that the controller 531 controls the lifting actuator 51b and the front and rear actuator 56b to adjust the handle 4 back to the original height and the original front and rear position respectively.

In addition, in addition to adjusting the height and front-to-back position of the handle 4, as shown in Figures 1 to 2 or Figures 3 to 4, the seat cushion 3 can also be adjusted in height and front-to-back position. The following will be explained using the first embodiment shown in Figures 1 to 2 as an example.

An inner rod 111 is inserted into the seat rod 11 of the electric bicycle in a telescopic manner, and the seat pad 3 and the upper ends of the inner rod 111 are connected to each other at a distance (in other words, the seat pad 3 is arranged on the frame 1).

The multi-directional adjustment device 5 also includes another lifting actuator 51a and another front-rear actuator 56a. The other lifting actuator 51a is arranged in the seat rod 11 and has another driving rod 511, and the other driving rod 511 is connected to the lower end of the inner rod 111. The other front-rear actuator 56a (which has, for example, a slide rail and an actuator body, not shown in the figure) is arranged at the upper end of the inner rod 111, and the other front-rear actuator 56a is also provided with a slider 561, and the slider 561 is driven by the actuator body to move along the slide rail, and the slider 561 is fixed to the seat pad 3. The other lifting actuator 51a and the other forward and backward actuator 56a are also connected to the controller 531, so that the controller 531 can also control the other driving rod 511 to move linearly, and can also control the slider 561 to be driven and move linearly, so as to drive the inner rod 111 together with the seat cushion 3 to extend and retract relative to the seat rod 11, and control the slider 561 to drive the seat cushion 3 to move forward and backward relative to the seat rod 11. It should be noted that the other lifting actuator 51a is the same as the aforementioned lifting actuator 51b, and only the size is different (for example, the other lifting actuator 52a shown in Figures 3 and 4 is also the same as the aforementioned lifting actuator 52b, and only the size is different therebetween).

Thereby, the controller 531 can simultaneously control the seat cushion 3 and the handle 4 to perform multi-directional adjustments.

In summary, the multi-directionally adjustable electric bicycle and its shared equipment in this application can indeed achieve the expected purpose of use and solve the deficiencies of the existing technology. It fully meets the requirements for a new patent application. Therefore, an application is filed in accordance with the Patent Law. Please check and approve the patent in this case to protect the rights of the creator of this application.

The above is only the preferred feasible embodiment of the present application, and does not limit the patent scope of the present application. All equivalent structural changes made by using the contents of the description and drawings of the present application are also included in the scope of the rights of the present application and are hereby stated.
