Detailed Implementation

[0042] In the description of the embodiments in this application, it should be noted that the term "lifting direction" is based on the attached... Figure 1 The orientation or positional relationship shown is merely for the convenience of describing the embodiments of this application and simplifying the description, and is not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the embodiments of this application.

[0043] This application provides a personal mobility vehicle, which includes, but is not limited to, electric bicycles, electric motorcycles, and gasoline-powered motorcycles.

[0044] Please see Figures 1 to 3 The mobility scooter of this application embodiment includes a vehicle body (not shown), a windshield adjustment device 10, and a windshield 20.

[0045] The windshield 20 is a light-transmitting protective component located on the front side of the vehicle body. Its main function is to reduce wind resistance during riding and prevent small stones or foreign objects from hitting the rider. The material of the windshield 20 is not limited. For example, the material of the windshield 20 can be tempered glass, polymethyl methacrylate (PMMA), polycarbonate (PC), etc.

[0046] The windshield adjustment device 10 is located on the vehicle body. Please refer to [link / reference]. Figures 1 to 5 , Figure 7The windshield adjustment device 10 includes a frame 11, a transmission module 12, and a power module 13. The transmission module 12 is mounted on the frame 11. The power module 13 includes a power output device 131 and a reduction gearbox 132 with an output shaft 132a. The reduction gearbox 132 is drive-connected to the power output device 131 and to the transmission module 12 via the output shaft 132a. The windshield 20 is connected to the transmission module 12. The power output by the power output device 131 is transmitted to the transmission module 12 via the reduction gearbox 132, so that the transmission module 12 moves to raise and lower the windshield 20. In other words, the windshield 20 can be raised and lowered relative to the vehicle body under the action of the transmission module 12.

[0047] Specifically, the power output device 131 is used to provide power for the movement of the transmission module 12, and the power output device 131 includes, but is not limited to, a drive motor.

[0048] The gearbox 132 is used to transmit the power output by the power output device 131 so that the transmission module 12 can move smoothly through speed change and torque increase.

[0049] The transmission module 12 moves to raise or lower the windshield 20 to a target lifting position. The target lifting position is the final position reached by the windshield 20 after it rises or falls.

[0050] In related technologies, for mobility scooters equipped with windshields, the windshields are generally fixed to the vehicle body. Fixed windshields have limited effect in reducing wind resistance and wind noise. Some riders still feel significant wind resistance during the ride, and their bodies are violently slapped by the wind, affecting the comfort of the ride. This discomfort is more pronounced when the speed is high and / or the rider is tall.

[0051] This application provides a windshield adjustment device 10 with a frame 11, a transmission module 12, and a power module 13. The reduction gearbox 132 of the power module 13 transmits the power output from the power output device 131 to the transmission module 12, enabling the transmission module 12 to smoothly drive the windshield 20 to rise and fall. Thus, the height of the windshield can be automatically adjusted according to the wind speed, or the rider can adjust the windshield height by operating the handlebar buttons, thereby improving riding comfort. The height of the windshield 20 can also be adjusted according to the rider's height, so that the windshield 20 can more accurately cover the area above the shoulders of riders of various heights without affecting the rider's vision. Therefore, the windshield 20 can effectively reduce wind resistance and wind noise for riders of different heights, so that riders of different heights can enjoy a more comfortable riding experience.

[0052] In some embodiments, please refer to Figures 2 to 4The transmission module 12 may include a windshield mounting bracket 121 and a linkage mechanism 122. The linkage mechanism 122 is hinged to the windshield mounting bracket 121 and the frame 11 respectively, and the output shaft 132a is connected to the linkage mechanism 122 for transmission.

[0053] Specifically, the windshield mounting bracket 121 is used to mount the windshield 20. The output shaft 132a of the gearbox 132 transmits the power output from the power output device 131 to the linkage mechanism 122, so that the linkage mechanism 122 can rotate relative to the frame 11 and the windshield mounting bracket 121. The windshield 20 can be raised and lowered under the drive of the linkage mechanism 122, and can also deflect towards or away from the rider during the raising and lowering process.

[0054] The linkage mechanism 122 has a simple structure and can achieve stepless adjustment. Therefore, by using the linkage mechanism 122 to drive the windshield 20 to rise and fall, the rising and falling position of the windshield 20 is not limited by a fixed gear, which makes it easier to adjust the position of the windshield 20.

[0055] The specific structural form of the linkage mechanism 122 is not limited; for example, please refer to [link to relevant documentation]. Figures 2 to 4 The linkage mechanism 122 may include two first linkages 1221 and two second linkages 1222. One first linkage 1221 and one second linkage 1222 are respectively provided on each of the opposite sides of the frame 11. The first linkages 1221 and second linkages 1222 on the same side are spaced apart along the lifting direction of the windshield 20. One end of the first linkage 1221 is hinged to the frame 11, one end of the second linkage 1222 is drivenly connected to the output shaft 132a, and the other ends of the first linkage 1221 and the second linkage 1222 are respectively hinged to the windshield mounting bracket 121.

[0056] In other words, the linkage mechanism 122 can be equipped with four links to drive the windshield 20 to rise and fall. The four links have high stability and reliability, which can ensure that the windshield 20 can rise and fall more smoothly and reliably.

[0057] To facilitate the transmission connection between the second link 1222 and the output shaft 132a, please refer to the example provided. Figure 1 , Figures 3 to 5 , Figure 7 The second link 1222 may have a mounting hole 1222a. The power module 13 may include a fixing seat 133 corresponding to the second link 1222, and the fixing seat 133 has mounting protrusions 133a. The fixing seat 133 is fixed to the output shaft 132a. For example, the fixing seat 133 may be sleeved on the output shaft 132a. The mounting protrusions 133a respectively engage with the mounting holes 1222a of the corresponding second link 1222 to prevent rotation. That is, the protrusions are inserted into the mounting holes 1222a, and the protrusions cannot rotate within the mounting holes 1222a.

[0058] Anti-rotation fit typically involves designing the mounting hole 1222a as a non-circular hole, with the shape of the protrusion matching the shape of the mounting hole 1222a. For example, Figures 3 to 5 The mounting hole 1222a shown has a rectangular cross-sectional shape, and the protrusion is also rectangular. In other embodiments, the mounting hole 1222a may also have a semi-circular, triangular, or other cross-sectional shape, as long as the shape of the protrusion is consistent with the cross-sectional shape of the mounting hole 1222a.

[0059] In other embodiments, the mounting hole 1222a may also be a round hole, and the mounting protrusion 133a may be anti-rotation by interference fit with the round hole.

[0060] Please continue reading. Figures 3 to 5 , Figures 3 to 5 The second link 1222 is located below the first link 1221 along the lifting direction of the windshield 20. The length of the second link 1222 is less than the length of the first link 1221. This arrangement allows the windshield 20 to maintain a more suitable tilt angle, which is more conducive to reducing wind resistance.

[0061] In other embodiments, the length of the second link 1222 may be the same as the length of the first link 1221.

[0062] In some embodiments, please refer to Figure 4 and Figure 5 The frame 11 may include a frame body 111 and two connecting shafts 112 fixed to the frame body 111. The first connecting rod 1221 is rotatably connected to the connecting shaft 112 in a one-to-one correspondence. That is, the connecting shaft 112 does not rotate, while the first connecting rod 1221 rotates around the corresponding connecting shaft 112.

[0063] Please continue reading. Figure 4 and Figure 5 In some embodiments, the transmission module 12 may further include torsion springs 123 sleeved on each connecting shaft 112, with the torsion springs 123 abutting against the frame 111 and the first connecting rod 1221 located on the same connecting shaft 112, respectively. The torsion springs 123 can provide torque to the first connecting rod 1221 during rotation. After the windshield 20 rises or falls relative to the vehicle body to the target lifting position under the drive of the transmission module 12, the torsion springs 123 can also prevent the first connecting rod 1221 from continuing to rotate through torque locking, thereby ensuring that the windshield 20 can be stably maintained at the target lifting position.

[0064] In some embodiments, please refer to Figures 3 to 5The transmission module 12 may also include two tension springs 124, which are respectively connected to the first link 1221 and the second link 1222 on the same side. That is, a tension spring 124 is provided on each of the opposite sides of the frame 11, and the tension spring 124 is connected to the first link 1221 and the second link 1222 on the same side of the frame 11. In this way, the transmission gap generated by the first link 1221 and the second link 1222 on the same side during rotation can be eliminated as much as possible, and the first link 1221 and the second link 1222 can be better prevented from shaking during rotation.

[0065] It should be noted that the transmission module 12 is not limited to using the linkage mechanism 122 to realize the transmission. The transmission module 12 can adopt any other structural form as needed, as long as it can drive the windshield 20 to rise and fall.

[0066] In some embodiments, please refer to Figure 3 , Figure 5 and Figure 8 The windshield mounting bracket 121 may have a first limiting structure 121a, which is located above the linkage mechanism 122 along the lifting direction of the windshield 20, to limit the relative rotation between the linkage mechanism 122 and the windshield mounting bracket 121. The purpose of limiting is to control the upward deflection angle of the windshield 20.

[0067] Taking the linkage mechanism 122 with the first link 1221 and the second link 1222 as an example, please refer to... Figure 3 and Figure 5 The first limiting structure 121a can be set on the upper side of the first connecting rod 1221 along the lifting direction of the windshield 20. When the first connecting rod 1221 and the windshield mounting bracket 121 rotate relative to each other to the limit position in the direction of approaching each other, the first limiting structure 121a abuts against the first connecting rod 1221, thereby preventing the first connecting rod 1221 and the windshield mounting bracket 121 from continuing to rotate in the direction of approaching each other, and thus preventing the angle between the side of the windshield 20 close to the connecting rod mechanism 122 and the horizontal plane from being too small, which would affect the effect of the windshield 20.

[0068] In some embodiments, please refer to Figure 3 , Figure 5 and Figure 8 The windshield mounting bracket 121 may also have a second limiting structure 121b, which is located below the linkage mechanism 122 along the lifting direction of the windshield 20, to limit the relative rotation between the linkage mechanism 122 and the windshield mounting bracket 121. The purpose of limiting is to control the downward deflection angle of the windshield 20.

[0069] Taking the linkage mechanism 122 with the first link 1221 and the second link 1222 as an example, please refer to... Figure 3 and Figure 5 The second limiting structure 121b can be set on the lower side of the second link 1222 along the lifting direction of the windshield 20. When the second link 1222 and the windshield mounting bracket 121 rotate relative to each other to the limit position in the direction of approaching each other, the second limiting structure 121b abuts against the second link 1222, thereby preventing the second link 1222 and the windshield mounting bracket 121 from continuing to rotate in the direction of approaching each other. This can prevent the angle between the side of the windshield 20 close to the link mechanism 122 and the horizontal plane from being too large and affecting the effect of the windshield 20.

[0070] In some embodiments, please refer to Figures 2 to 5 The power module 13 may include a housing 134, which has a receiving cavity 1341a and a through hole 1341b communicating with the receiving cavity 1341a. The power output device 131 and the reduction gearbox 132 are disposed in the receiving cavity 1341a, and the output shaft 132a extends out of the housing 134 through the through hole 1341b to be connected to the transmission module 12 for transmission. In other words, the power output device 131 and the reduction gearbox 132 can be integrated into a whole through the housing 134, thereby making the overall structure of the power module 13 more compact.

[0071] Please see Figures 2 to 6 The housing 134 may include a body 1341 and a cover 1342. The body 1341 has a receiving cavity 1341a, a through hole 1341b, and an opening (not shown) communicating with the receiving cavity 1341a. The through hole 1341b has an opening communicating with the opening. The output shaft 132a enters the through hole 1341b through the opening. The cover 1342 is closable and connectable to the body 1341 to cover the opening. That is, the opening is used for disassembling and assembling the power output device 131 and the gearbox 132, while the through hole 1341b is notched. During the process of placing the gearbox 132 into the receiving cavity 1341a, the output shaft 132a can directly enter the through hole 1341b through the opening. After the cover 1342 is closed, it blocks the opening and confines the power output device 131 and the gearbox 132 within the receiving cavity 1341a, and confines the output shaft 132a within the through hole 1341b. This type of housing 134 facilitates the disassembly and assembly of the gearbox 132, and the cover 1342 also provides good protection for the power output device 131 and the gearbox 132.

[0072] In other embodiments, the box 134 may only have a box body 1341, without a box lid 1342.

[0073] Please continue reading. Figure 5The housing 134 can be detachably connected to the rack 11, for example, see [reference needed]. Figure 5 The housing 134 may be provided with a connecting plate 1343, which may be provided on the outer surface of the housing 1341. The connecting plate 1343 and the frame 11 may be fastened together by screws or other fasteners. In other embodiments, the housing 134 may also be detachably connected to the frame 11 by means of snap-fit ​​or other means.

[0074] Please see Figure 5 and Figure 6 The frame 11 may also have a limiting groove ( Figure 5 and Figure 6 The space enclosed by the middle groove wall 11a is the limiting groove. The box body 134 is at least partially located in the limiting groove. In other words, the box body 134 can be limited by setting the limiting groove, thereby ensuring that the installation position of the power module 13 will not deviate, and thus improving the accuracy of the transmission connection between the output shaft 132a and the transmission module 12.

[0075] Figure 5 and Figure 6 The portion of the box body 1341 of the box body 134 shown, where the through hole 1341b is provided, is also located within the limiting groove. Therefore, a clearance notch 11c is correspondingly provided on the groove wall 11a. The clearance notch 11c avoids the through hole 1341b. That is to say, when the box body 134 is placed in the limiting groove, the output shaft 132a also enters the clearance notch 11c accordingly. This arrangement can ensure that the limiting groove has sufficient depth to accommodate the box body 134 and prevent the groove wall 11a from interfering with the output shaft 132a.

[0076] It is understandable that if the part of the box body 1341 with the through hole 1341b is located outside the limiting groove, then there is no need to set the avoidance notch 11c on the groove wall 11a.

[0077] Further, please refer to Figure 2 , Figure 3 and Figure 6 The frame 11 may also have a mounting notch 11b, through which the portion of the output shaft 132a extending outside the housing 134 enters the mounting notch 11b. The windshield adjustment device 10 also includes a baffle 14, which blocks the opening of the mounting notch 11b and is detachably connected to the frame 11. In other words, by blocking the opening of the mounting notch 11b, the baffle 14 can restrict the output shaft 132a within the mounting notch 11b, thereby providing a better limiting effect on the output shaft 132a.

[0078] In some embodiments, please refer to Figure 4 and Figure 7The windshield adjustment device 10 may also include a detection component 15, which is used to detect the position of the windshield 20 and output a position detection signal.

[0079] Accordingly, the mobility scooter may include a controller that is signal-connected to the detection component 15 and the power output device 131, respectively, to control the power output device 131 to start and stop according to the position detection signal output by the detection component 15.

[0080] Specifically, in some scenarios, the controller can first determine the target lifting position of the windshield 20, and then control the power output device 131 to start and stop based on the detection results of the detection component 15.

[0081] For example, before riding, the rider can issue a lifting command to the controller through voice, manual selection or manual input, so that the windshield 20 can be raised or lowered to a specific target position (for example, the rider can specify that the windshield 20 can be raised by 3cm or lowered by 2cm through the lifting command). The controller then controls the power output device 131 accordingly based on the detection results of the detection component 15.

[0082] For example, during the operation of a mobility scooter, the faster the speed, the greater the wind resistance and the stronger the wind noise. Therefore, the position of the windshield 20 can be adjusted according to the change in speed. In other words, the controller can first determine the target lifting position of the windshield 20 based on the change in speed (in some embodiments, the target lifting position of the windshield 20 can also be determined based on the speed and the rider's height). Then, based on the detection results of the detection component 15, the controller can control the power output device 131 accordingly so that the transmission module 12 can drive the windshield 20 to move to the target lifting position. This can better ensure that the position of the windshield 20 matches the current speed, so that the rider can enjoy a more comfortable riding experience at different speeds.

[0083] For example, before starting the power output device 131, the controller can receive the position detection signal output by the detection component 15, determine the current position of the windshield 20 based on the position detection signal, calculate the difference between the current position and the target lifting position, and control the power output device 131 to start based on the difference.

[0084] In other words, the difference can be used to determine whether the windshield 20 is rising or falling, and the specific height by which it rises or falls. For example, if the result of subtracting the current position from the target position is positive, the transmission module 12 will cause the windshield 20 to rise; if the result is negative, the transmission module 12 will cause the windshield 20 to fall. Assuming the result of subtracting the current position from the target position is 3cm, the transmission module 12 will cause the windshield 20 to rise 3cm before reaching the target position; assuming the result is -2cm, the transmission module 12 will cause the windshield 20 to fall 2cm before reaching the target position.

[0085] For example, after the power output device 131 is started, the controller can receive the position detection signal output by the detection component 15. If the windshield 20 is determined to have reached the target lifting position based on the position detection signal, the power output device 131 is stopped.

[0086] In other words, when the position detection signal determines that the windshield 20 has reached the target lifting position, the controller can control the power output device 131 to stop operating so that the windshield 20 can remain at the target lifting position.

[0087] The method by which the detection component 15 detects the position of the windshield 20 is not limited; for example, please refer to [link to relevant documentation]. Figure 7 The detection component 15 can detect the rotation angle of the output shaft 132a and output a position detection signal. In other words, the detection component 15 can detect the current rotation angle of the output shaft 132a and determine the current position of the windshield 20 by the rotation angle.

[0088] The method by which the detection component 15 detects the rotation angle of the output shaft 132a is not limited; for example, please refer to [link to relevant documentation]. Figure 7 The detection component 15 may include a first gear 151, a second gear 152, and an angle sensor 153. The first gear 151 is sleeved on the output shaft 132a and meshes with the second gear 152. Figure 7 The angle sensor 153 shown rotates coaxially with the second gear 152 and outputs a position detection signal. That is, during the rotation of the output shaft 132a, the first gear 151 is driven to rotate together, and the second gear 152, which meshes with the first gear 151, also rotates together with the first gear 151. The angle sensor 153 rotates coaxially with the second gear 152, and the angle sensor 153 outputs the position detection signal during the rotation process.

[0089] In other embodiments, in addition to the first gear 151, the second gear 152, and the angle sensor 153, the detection component 15 may also be equipped with a magnet. The magnet may be disposed on the second gear 152 and rotate under the drive of the second gear 152. The angle sensor 153 may be used to detect the rotating magnet and output a position detection signal. That is, the angle sensor 153 may also remain stationary and not rotate coaxially with the second gear 152. The angle sensor 153 outputs a position detection signal by detecting the rotating magnet.

[0090] For the power module 13 with housing 134, the detection component 15 can also be set in the receiving cavity 1341a. That is to say, the space in the receiving cavity 1341a can be fully utilized to accommodate the detection component 15, thereby reducing the installation space occupied by the detection component 15.

[0091] In some other embodiments, the windshield adjustment device 10 may not have the detection component 15. For example, before riding, the rider can freely adjust the position of the windshield 20. That is, without specifying a specific height to rise or fall, the rider can start the power output device 131 according to their own preferences, so that the transmission module 12 drives the windshield 20 to rise or fall. When the windshield 20 rises or falls to a suitable position, the power output device 131 can be directly controlled to stop running.
