[0054] The utility model discloses a scooter's locking device 30, and the first cooperation 101 of vehicle body 10 and the second cooperation 201 of control member 20 mutually cooperate, by being arranged in installation cavity 2011 with wedge block 11, drive assembly 2 is used to drive wedge block 11 to move along the direction of being close to or away from the vehicle body 10, under the mutual cooperation of the second slope 111 and the first slope 20111, make wedge block 11 abut or release the first cooperation 101, realize the locking and release of the first cooperation 101 and the second cooperation 201, further realize the installation and dismounting of vehicle body 10 and control member 20, and the locking force is stable and reliable, and the overall coordination and security of the scooter are improved.

[0055] Specifically, as Figures 1-12 The first cooperation 101 and the second cooperation 201 are connected by sleeving, for example, the first cooperation 101 is sleeved on the outer periphery of the second cooperation 201, or the second cooperation 201 is sleeved on the outer periphery of the first cooperation 101. Through the sleeving connection of the first cooperation 101 and the second cooperation 201, the wedge block 11 arranged in the installation cavity 2011 of the second cooperation 201 is abutted or released with the first cooperation 101.

[0056] For ease of description, the description is taken as an example that the second cooperation part 201 is located in front of the first cooperation part 101, the driving assembly 2 is movable relative to the operating member 20, the rear end of the driving assembly 2 is connected with the wedge block 11 to drive the wedge block 11 to move forward or backward, and due to the cooperation between the second inclined surface 111 of the outer circumferential surface of the wedge block 11 and the first inclined surface 20111 of the inner circumferential surface of the mounting cavity 2011, when the driving assembly 2 drives the wedge block 11 to move forward, the wedge block 11 moves upward or downward to abut against the first cooperation part 101, when the driving assembly 2 drives the wedge block 11 to move backward, the wedge block 11 moves upward or downward to release the first cooperation part 101, the locking and releasing of the first cooperation part 101 and the second cooperation part 201 are realized, and the mounting and dismounting of the vehicle body 10 and the operating member 20 are realized.

[0057] In some embodiments, the first cooperation part 101 is a cooperation shaft 1011, the mounting cavity 2011 has an opening 20112 at one end facing the first cooperation part 101, the cooperation shaft 1011 extends into the mounting cavity 2011 from the opening 20112, and the wedge block 11 abuts against the outer surface of the cooperation shaft 1011 when the second inclined surface 111 abuts against the first inclined surface 20111.

[0058] Specifically, as shown in Figures 1-7 , the rear end opening 20112 of the mounting cavity 2011 is so as to make the cooperation shaft 1011 extend into the mounting cavity 2011 in a direction from rear to front. When the driving assembly 2 drives the wedge block 11 to move forward, due to the cooperation between the second inclined surface 111 and the first inclined surface 20111, the wedge block 11 moves along the inclined direction of the first inclined surface 20111, that is, the wedge block 11 moves upward while moving forward, the wedge block 11 abuts against the outer surface of the cooperation shaft 1011 to lock the cooperation shaft 1011, the locking of the first cooperation part 101 and the second cooperation part 201 is realized, and the mounting of the vehicle body 10 and the operating member 20 is realized.

[0059] When the driving assembly 2 drives the wedge block 11 to move backward, due to the cooperation between the second inclined surface 111 and the first inclined surface 20111, the wedge block 11 moves along the inclined direction of the first inclined surface 20111, that is, the wedge block 11 moves downward while moving backward, the wedge block 11 moves downward to separate from the outer surface of the cooperation shaft 1011 to release the cooperation shaft 1011, the cooperation shaft 1011 is facilitated to be separated from the first cooperation part 101, and the dismounting of the vehicle body 10 and the operating member 20 is realized.

[0060] In some embodiments, the cooperation shaft 1011 has a flange 10111 at one end away from the vehicle body 10, and the wedge block 11 abuts against the one end of the flange 10111 facing the vehicle body 10 when the second inclined surface 111 abuts against the first inclined surface 20111.

[0061] Specifically, as shown in Figure 3 , Figure 4 andFigure 7 As shown, the front end of the matching shaft 1011 has a flange 10111, when the locking device 30 locks the first matching part 101 and the second matching part 201 in the locked state, the second inclined surface 111 abuts against the first inclined surface 20111, the wedge block 11 abuts against the outer surface of the matching shaft 1011, and the front end of the wedge block 11 abuts against the rear end of the flange 10111. Through the arrangement of the flange 10111, the matching shaft 1011 is prevented from falling off when the locking device 30 loosens.

[0062] Optionally, the matching shaft 1011 comprises, from front to back, the flange 10111, the matching section 10112, the protruding section 10113, and the main body section 10114, one end of the main body section 10114 away from the protruding section 10113 is connected with the frame of the vehicle body 10, and the front end of the flange 10111 abuts against the inner wall surface of the mounting cavity 2011. Through the arrangement of the flange 10111 and the protruding section 10113, the front end and the rear end of the wedge block 11 can be limited, so that the wedge block 11 is prevented from moving in the front-rear direction when being locked, and the reliability of the locking device 30 is improved.

[0063] In some embodiments, the first matching part 101 comprises a matching groove 1012, at least part of the second matching part 201 is matched in the matching groove 1012, the matching groove 1012 is communicated with the mounting cavity 2011, and the inner wall surface of the matching groove 1012 is provided with a recessed part 10121. When the second inclined surface 111 abuts against the first inclined surface 20111, the wedge block 11 extends out of the mounting cavity 2011 and abuts against the recessed part 10121.

[0064] Specifically, as shown, Figures 9-12 the rear end of the second matching part 201 extends into the matching groove 1012. When the driving assembly 2 drives the wedge block 11 to move forward, due to the cooperation between the second inclined surface 111 and the first inclined surface 20111, the wedge block 11 moves along the inclined direction of the first inclined surface 20111, that is, the wedge block 11 moves downward while moving forward. Since the matching groove 1012 is communicated with the mounting cavity 2011, the downward movement of the wedge block 11 causes part of the wedge block 11 to extend out of the mounting cavity 2011 and abut against the recessed part 10121, thereby achieving the locking of the first matching part 101 and the second matching part 201, and further achieving the installation of the vehicle body 10 and the operating member 20.

[0065] When the driving assembly 2 drives the wedge block 11 to move backward, due to the cooperation between the second inclined surface 111 and the first inclined surface 20111, the wedge block 11 moves along the inclined direction of the first inclined surface 20111, that is, the wedge block 11 moves upward while moving backward. The upward movement of the wedge block 11 causes the wedge block 11 to separate from the recessed part 10121, thereby facilitating the disengagement of the second matching part 201 from the first matching part 101, and further achieving the disassembly of the vehicle body 10 and the operating member 20.

[0066] In the embodiment, the first fitting part 101 is arranged as the fitting groove 1012, the protruding part of the vehicle body 10 is reduced, and the overall coordination of the vehicle body 10 is improved.

[0067] In some embodiments, as shown in Figures 11-12 The outer circumferential surface of the wedge block 11 has the protrusion 112, which is arranged in a spaced manner with the second inclined surface 111 and is in abutment with the recessed part 10121 when the second inclined surface 111 abuts against the first inclined surface 20111. Through the cooperation of the protrusion 112 and the recessed part 10121, the wedge block 11 is facilitated to lock and release the first fitting part 101.

[0068] Alternatively, the recessed part 10121 can be through the groove wall of the fitting groove 1012, or the recessed depth of the recessed part 10121 is smaller than the groove wall of the fitting groove 1012, that is, the recessed part 10121 does not penetrate the groove wall of the fitting groove 1012. For example, the recessed depth of the recessed part 10121 is greater than or equal to the height of the protrusion 112 of the wedge block 11.

[0069] In some embodiments, the driving assembly 2 comprises a driving piece 21 and a pull rod 22. The driving piece 21 is rotatable relative to the operating piece 20 and is in abutment with one end of the second fitting part 201 away from the first fitting part 101. The pull rod 22 is arranged in the second fitting part 201 and extends into the mounting cavity 2011. One end of the pull rod 22 is connected with the driving piece 21, and the other end of the pull rod 22 is arranged in the wedge block 11 and is in clearance fit with the wedge block 11. When the driving piece 21 rotates, the pull rod 22 and the wedge block 11 are driven to move along the axial direction of the pull rod 22.

[0070] Specifically, as shown in Figures 2-4 The driving piece 21 is in abutment with the front end of the second fitting part 201, and the pull rod 22 is arranged in the second fitting part 201. The axial direction of the pull rod 22 is consistent with the front-rear direction. The front end of the pull rod 22 is connected with the driving piece 21, and the rear end of the pull rod 22 is arranged in the mounting cavity 2011 and is connected with the wedge block 11. When the driving piece 21 rotates, the pull rod 22 is driven to move forward or backward, and the pull rod 22 drives the wedge block 11 to move forward or backward. Since the pull rod 22 and the wedge block 11 are in clearance fit, when the second inclined surface 111 of the wedge block 11 moves along the first inclined surface 20111, the wedge block 11 can move upward or downward to abut against and release the first fitting part 101, thereby achieving the installation and disassembly of the first fitting part 101 and the second fitting part 201.

[0071] In some embodiments, the wedge block 11 has a through hole 113, the other end of the pull rod 22 extends into the through hole 113, and the driving assembly 2 further comprises a fastener 23 connected with the other end of the pull rod 22. The inner wall surface of the through hole 113 has a boss 1131, and the fastener 23 is in abutment with the boss 1131.

[0072] Specifically, as shown inFigure 2 and Figure 6 As shown, the wedge 11 has a through hole 113 that runs through the wedge 11 in the front-to-back direction. The rear end of the pull rod 22 extends into the through hole 113 and is connected to the fastener 23. Since the wedge 11 and the pull rod 22 are in clearance fit, the pull rod 22 and the wedge 11 are connected by the fastener 23 abutting against the boss 1131.

[0073] Optionally, the fastener 23 is threadedly connected to the pull rod 22. By rotating the fastener 23 clockwise, the locking force of the locking device 30 is increased; by rotating the fastener 23 counterclockwise, the locking force of the locking device 30 is decreased. The amount of tightening of the fastener 23 is used to control the magnitude of the locking force of the locking device 30, thereby achieving rapid adjustment of the locking force.

[0074] In some embodiments, the drive assembly 2 further includes an elastic element 24 disposed within the mounting cavity 2011, the elastic element 24 abutting between the inner wall surface of the mounting cavity 2011 and the wedge block 11 to provide an elastic force toward the vehicle body 10 to the wedge block 11.

[0075] Specifically, such as Figure 3 , Figure 7 and Figure 11 As shown, the elastic element 24 is sleeved on the pull rod 22. The front end of the elastic element 24 abuts against the inner wall of the mounting cavity 2011, and the rear end of the elastic element 24 abuts against the front end of the wedge block 11. When the locking device 30 is in the locked state, the elastic element 24 is compressed to allow space for the wedge block 11 to move forward. When the locking device 30 is in the released state, the elastic element 24 extends to push the wedge block 11 to move backward, causing the wedge block 11 to release the first mating part 101, thereby facilitating the installation and removal of the vehicle body 10 and the operating element 20.

[0076] Optionally, the boss 1131 is provided at the front end or rear end of the through hole 113 or between the front and rear ends. When the boss 1131 is provided in the middle of the through hole 113, a receiving space 1132 is formed between the front end of the boss 1131 and the front end of the through hole 113, and between the rear end of the boss 1131 and the rear end of the through hole 113. The receiving space 1132 located at the rear facilitates the reception of the fastener 23, and the receiving space 1132 located at the front facilitates the reception of the elastic element 24, which facilitates the installation of the elastic element 24 and improves the stability of the elastic element 24.

[0077] In some embodiments, the drive member 21 includes an eccentric wheel 211, a rotating shaft 212, and a wrench 213. The wrench 213 is connected to the outer peripheral surface of the eccentric wheel 211. The eccentric wheel 211 abuts against the second mating part 201. The eccentric wheel 211 has an eccentric hole 2111. The rotating shaft 212 passes through the eccentric hole 2111. The eccentric wheel 211 is rotatable about the axis of the rotating shaft 212.

[0078] Specifically, such asFigures 2-4 and Figures 10-12 As shown in the figure, the eccentric wheel 211 is located in front of the second matching part 201, the outer circumferential surface of the eccentric wheel 211 abuts against the outer circumferential surface of the front end of the second matching part 201, the eccentric wheel 211 is connected with the upper end of the pull rod 22, and the rotating shaft 212 is arranged in the eccentric hole 2111. When the wrench 213 drives the eccentric wheel 211 to rotate around the rotating shaft 212, the rotating shaft 212 is driven to move forward or backward, the pull rod 22 is arranged in the rotating shaft 212, the rotating shaft 212 is driven to move forward or backward, the pull rod 22 is driven to move forward or backward, and the wedge block 11 is driven to move forward or backward, thereby improving the operation convenience.

[0079] When the eccentric wheel 211 drives the rotating shaft 212 to move forward, the pull rod 22 is driven to move forward, and the wedge block 11 is driven to move forward, so that the wedge block 11 abuts against the first matching part 101, and the locking of the vehicle body 10 and the operating part 20 is realized. When the eccentric wheel 211 drives the rotating shaft 212 to move backward, the pull rod 22 is driven to move backward, the elastic member 24 drives the wedge block 11 to move backward, and the wedge block 11 releases the first matching part 101, thereby facilitating the disassembly of the vehicle body 10 and the operating part 20.

[0080] Optionally, the driving assembly 2 further comprises a gasket 25, one end of the gasket 25 abuts against the second matching part 201, and the other end of the gasket 25 abuts against the outer circumferential surface of the eccentric wheel 211. Through the arrangement of the gasket 25, the friction between the eccentric wheel 211 and the second matching part 201 is reduced, and the service life of the driving assembly 2 is improved.

[0081] The outer circumferential surface of the eccentric wheel 211 abuts against the second matching part 201, the radial dimension of the rotating axis of the eccentric wheel 211 to the outer circumferential surface of the eccentric wheel 211 is different, when the eccentric wheel 211 rotates relative to the second matching part 201, the position of the pull rod 22 in the front-back direction is more forward when the position with large radial dimension abuts against the second matching part 201 than when the position with small radial dimension abuts against the second matching part 201, the locking device 30 is in the locking state when the position with large radial dimension abuts against the second matching part 201, and the locking device 30 is in the releasing state when the position with small radial dimension abuts against the second matching part 201. In other words, when the eccentric wheel 211 rotates from the position with large radial dimension to the position with small radial dimension, the eccentric wheel 211 drives the pull rod 22 to move backward, and vice versa, when the eccentric wheel 211 rotates from the position with small radial dimension to the position with large radial dimension, the eccentric wheel 211 drives the pull rod 22 to move forward.

[0082] In some embodiments, the drive member 21 includes a disc portion 214 and a wrench 213. The wrench 213 is connected to the outer peripheral surface of the disc portion 214. One side of the disc portion 214 and one side of the second mating portion 201 have an annular first boss 2141. The first boss 2141 has a highest protrusion 21411, the height of which is greater than the height of the remaining circumferential positions of the first boss 2141. The other side of the disc portion 214 and one side of the second mating portion 201 have a first groove 2012 that mates with the first boss 2141. The bottom surface of the first groove 2012 has a highest position 20121, the height of which is greater than the height of the other positions in the circumferential direction of the first groove 2012. The disc portion 214 can rotate about the axis of the pull rod 22 relative to the second mating portion 201 so that the highest position 20121 abuts against and moves away from the highest protrusion 21411. The highest position 20121 abuts against the highest protrusion 21411 so that the locking member 1 presses against the first mating portion 101. The highest position 20121 moves away from the highest protrusion 21411 so that the locking member 1 releases the first mating portion 101.

[0083] Specifically, such as Figures 6-8 As shown, one side of the disc portion 214 and one side of the second mating portion 201 have an annular first boss 2141, and the other side has a first groove 2012 that mates with the first boss 2141. When the disc portion 214 rotates in the front-rear direction, causing the highest protrusion 21411 of the first boss 2141 to move away from the highest position 20121 of the bottom surface of the first groove 2012, the disc portion 214 drives the wedge block 11 to move backward. The wedge block 11 releases the first mating portion 101, thus facilitating the disassembly of the vehicle body 10 and the control component 20. When the highest protrusion 21411 of the first boss 2141 abuts against the highest position 20121 of the bottom surface of the first groove 2012, the disc portion 214 drives the wedge block 11 to move forward. The wedge block 11 abuts against the first mating portion 101, locking the first mating portion 101 and the second mating portion 201.

[0084] Optionally, the rear side of the disc portion 214 has a first boss 2141, and the front side of the second mating portion 201 has a first groove 2012. The pull rod 22 passes through the disc portion 214 and the second mating portion 201 in sequence, and the rotation of the disc portion 214 drives the pull rod 22 to move forward or backward.

[0085] Alternatively, the wrench 213 can be used to directly drive the disc portion 214 to rotate relative to the second mating portion 201, making the operation simple and convenient.

[0086] In some embodiments, the first boss 2141 comprises a gradient protrusion 21412 extending along the circumference thereof, the height of the gradient protrusion 21412 gradually changes along the circumference of the first boss 2141, the highest protrusion 21411 is formed at one end of the gradient protrusion 21412, and the bottom surface of the first groove 2012 comprises a gradient surface 20122 extending along the circumference thereof, the depth of the gradient surface 20122 gradually changes along the circumference of the first groove 2012, and the gradient surface 20122 is cooperable with the gradient protrusion 21412, and the highest position 20121 is formed at one end of the gradient surface 20122.

[0087] Specifically, as shown in Figures 6-8 the height of the gradient protrusion 21412 gradually increases along the circumference of the first boss 2141 to form the highest protrusion 21411 at one end of the gradient protrusion 21412 and the lowest protrusion 21413 at the other end, and the depth of the gradient surface 20122 gradually increases along the circumference of the first groove 2012 to form the highest position 20121 at one end of the gradient surface 20122 and the lowest position 20123 at the other end, and through the cooperation of the gradient protrusion 21412 and the gradient surface 20122, when the highest protrusion 21411 and the highest position 20121 abut each other by rotating the disc part 214 around the front-back direction, the wedge 11 locks the first fitting part 101, at this time, the disc part 214 cannot continue to rotate, and when the highest protrusion 21411 and the lowest position 20123 abut each other by reversing the rotation of the disc part 214, the wedge 11 releases the first fitting part 101.

[0088] Alternatively, the gradient protrusion 21412 is a plurality of gradient protrusions 21412 arranged at intervals along the circumference of the first boss 2141, the gradient surface 20122 is a plurality of gradient surfaces 20122 arranged at intervals along the circumference of the first groove 2012, and the plurality of gradient surfaces 20122 and the plurality of gradient protrusions 21412 correspond one-to-one. The arrangement of the plurality of gradient protrusions 21412 and the plurality of gradient surfaces 20122 can limit the rotation direction and rotation angle of the disc part 214, so that the locking force of the disc part 214 is consistent, thereby improving the reliability of the locking device 30.

[0089] In some embodiments, the outer circumferential surface of the side of the second fitting part 201 away from the first fitting part 101 has a receiving part 2013, and at least part of the driving member 21 is located in the receiving part 2013.

[0090] Specifically, as shown in Figures 1-12 the outer circumferential surface of the front side of the second fitting part 201 has a receiving part 2013, and by arranging at least part of the driving member 21 in the receiving part 2013, the exposed part of the locking device 30 is reduced, and the overall coordination of the scooter is improved.

[0091] Optionally, the eccentric wheel 211 is located in the accommodating portion 2013, and at least part of the spanner 213 is located in the accommodating portion 2013. For example, when the locking device 20 is in the locked state, the front side of the spanner 213 is flush with the front end surface of the accommodating portion 2013, and the upper end of the spanner 213 is reserved from the upper end surface of the accommodating portion 2013 to facilitate the spanner 213 to be turned while further reducing the exposed part of the spanner 213. Alternatively, when the locking device 20 is in the locked state, the front side of the spanner 213 is located outside the accommodating portion 2013, and the rear side of the spanner 213 is located inside the accommodating portion 2013, thereby improving the operation convenience of the spanner 213.

[0092] Optionally, when the driving member 21 comprises the disc portion 214, the disc portion 214 is located in the accommodating portion 2013, and the spanner 213 is located outside the accommodating portion 2013. Since the disc portion 214 can rotate relative to the second matching portion 201 in the front-rear direction, the spanner 213 is arranged outside the accommodating portion 2013 to facilitate the rotation of the disc portion 214. For example, the rear side of the spanner 213 is flush with the front end surface of the accommodating portion 2013 to facilitate the spanner 213 to be turned while reducing the exposed part of the spanner 213.

[0093] In some embodiments, as shown in Figures 3-4 Optionally, the bottom wall of the accommodating portion 2013 is provided with a protrusion 20131, and the spanner 213 abuts against the protrusion 20131 when the wedge block 11 abuts against the first matching portion 101. The protrusion 20131 is arranged to facilitate the determination of whether the spanner 213 is turned to the right position, so that the locking force of the locking device 30 is consistent, thereby improving the reliability of the locking device 30.

[0094] Optionally, when the driving member 21 comprises the disc portion 214, since the disc portion 214 can rotate relative to the second matching portion 201 in the front-rear direction, by arranging a limiting member on the bottom wall of the accommodating portion 2013 and arranging a limiting groove matched with the limiting member on the spanner 213, the radial displacement of the disc portion 214 can be reduced, and the reliability of the locking device 30 can be improved.

[0095] The scooter of the embodiment of the utility model comprises the locking device 30 of the scooter of the above-mentioned embodiment.

[0096] The scooter of the embodiment of the utility model comprises the locking device 30 of the above-mentioned embodiment, so that the installation and dismounting of the vehicle body 10 and the operating member 20 are facilitated, and the overall coordination and safety of the scooter are improved.

[0097] In some embodiments, the scooter is a balance car, the steering member 20 of the scooter is a leg control rod of the balance car, and the steering member 20 further comprises an operating rod 202, the bottom of the operating rod 202 being connected with the second matching part 201. Since the bottom of the operating rod 202 is connected with the second matching part 201, the locking and releasing of the second matching part 201 and the first matching part 101 by the locking device 30 can realize the locking and releasing of the operating rod 202 and the vehicle body 10.

[0098] Optionally, the balance car further comprises a wheel, the wheel being connected with the vehicle body 10.

[0099] In some embodiments, the locking device 30 is used for the mounting and dismounting of the steering member 20 and the vehicle body 10. In this embodiment, the locking and releasing of the first matching part 101 and the second matching part 201 by the locking device 30 can facilitate the mounting and dismounting of the steering member 20 and the vehicle body 10.
