Description

Technical Field

[0001] This utility model relates to the field of scooter frame technology, and more specifically, to an aluminum alloy scooter frame. Background Technology

[0002] Scooters are a means of transportation for users to ride. Currently, Chinese Patent Announcement No. CN211710994U discloses a scooter frame and a scooter with the frame installed. In this scooter structure, the scooter handlebar assembly cannot be folded relative to the frame, which results in the scooter taking up a lot of space when transporting or carrying it, thus making it inconvenient to transport and carry. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide an aluminum alloy frame for scooters, in which the internal uprights and handlebars can be folded relative to the footboard frame, thus giving the scooter the advantage of occupying little space when carrying or transporting it.

[0004] This utility model provides an aluminum alloy frame for a scooter, including a footboard frame, a column, a front shock absorber plate, a folding lower seat, a folding upper seat, a handlebar, and a hollow upright. A support shaft is provided at the top of the front end of the front shock absorber plate. A rotating sleeve is provided at the front end of the column, rotatably fitted onto the support shaft. The rear end of the column is fixed to the front end of the footboard frame. The folding lower seat is fixed to the upper end of the support shaft. The rear side of the folding upper seat is rotatably connected to the rear side of the folding lower seat. The lower end of the upright is fixed to the upper end of the folding upper seat. The handlebar is fixed to the upper end of the upright. The automotive aluminum alloy frame also includes a locking assembly; the locking assembly includes a hand-tightening bolt and a "[" shaped clamping member; the screw part of the hand-tightening bolt passes through the clamping member and is rotatably connected to the clamping member, and the screw part is threadedly connected to the front side of the folding lower seat. The front side of the folding lower seat and the front side of the folding upper seat are respectively provided with a first groove and a second groove; when the hand-tightening bolt is rotated so that the handle of the hand-tightening bolt pushes the clamping member toward one side of the folding lower seat and the folding upper seat, the two ends of the clamping member are respectively engaged in the first groove and the second groove and lock the folding lower seat and the folding upper seat.

[0005] By adopting the above structure, when the locking assembly releases the locking state of the folding lower seat and the folding upper seat, the upright and the handlebar can be folded relative to the pedal frame. This gives the scooter the advantage of occupying little space when carrying or transporting it, thus making it more convenient to carry and transport.

[0006] In one possible implementation, the inner walls at both ends of the clamping member gradually slope away from the clamping member from front to back, forming wedge-shaped engaging portions. These two engaging portions are respectively used to engage in the first and second slots. The shapes of the first and second slots are respectively adapted to the shapes of the engaging portions at corresponding positions. With this structure, when the hand-tightening bolt is tightened to push the clamping member towards the lower and upper folding seats, the two wedge-shaped engaging portions can more easily engage in the first... The first and second slots facilitate the engagement of the locking part with the first and second slots. Since the shapes of the first and second slots are adapted to the shapes of the locking parts at corresponding positions, as the two wedge-shaped locking parts are gradually inserted into the first and second slots, a squeezing force is applied to the front side of the lower folding seat and the front side of the upper folding seat, causing them to move closer together. This allows the front side of the upper folding seat to more reliably abut against the front side of the lower folding seat and securely fasten together.

[0007] In one possible implementation, an annular protrusion is provided on the outer wall of the screw portion, and the annular protrusion abuts against the inner wall of the clamping member. With this structure, under the action of the annular protrusion, since the annular protrusion abuts against the inner wall of the clamping member, when the hand-tightening bolt is turned to move the hand-tightening bolt away from the clamping member, the annular protrusion can push the clamping member so that the clamping member moves away from the lower folding seat and the upper folding seat along with the hand-tightening bolt, thereby making it easy for the clamping member to disengage from the first and second slots and achieve a locking state for the lower folding seat and the upper folding seat. In addition, under the action of the annular protrusion, it is possible to prevent the clamping member from axially disengaging from the screw portion.

[0008] In one possible implementation, the front end of the screw is inserted into the handle and fastened to the handle by a pin; with this structure, the front end of the screw can be reliably fastened to the handle by the action of the pin.

[0009] In one possible implementation, the rear side of the folding upper seat and the rear side of the folding lower seat are rotatably connected by a pivot; with this structure, the rear side of the folding upper seat can be reliably rotatably connected to the rear side of the folding lower seat via the pivot.

[0010] In one possible implementation, the lower end of the folding base is provided with a slot, the upper end of the support shaft is inserted into the slot, and the folding base is fastened to the upper end of the support shaft by bolts. With this structure, since the upper end of the support shaft is inserted into the slot, the folding base and the support shaft can be limited, and the folding base can be reliably fastened to the support shaft by the bolts.

[0011] In one possible implementation, a first insert is provided at the upper end of the folding upper seat. The first insert is inserted into the lower end of the upright. The lower end of the upright is fastened to the first insert by a number of first screws. With this structure, after the first insert is engaged with the lower end of the upright, the folding upper seat can pre-assemble and limit the upright, thereby facilitating the fastening of the first screws to the folding upper seat and the upright, and improving the fixing firmness and reliability of the folding upper seat and the upright.

[0012] In one possible implementation, a lower pressure bracket is fixed to the upper end of the pole, and an upper pressure bracket is fixed to the lower pressure bracket by a bolt assembly. The middle part of the handlebar is pressed against the lower pressure bracket by the upper pressure bracket. Through the cooperation of the upper and lower pressure brackets, the handlebar can be reliably fixed to the upper end of the pole.

[0013] In one possible implementation, a second insert is provided at the lower end of the pressure block. The second insert is inserted into the upper end of the upright and is fastened to the upper end of the upright by a number of second screws. With this structure, after the second insert is engaged with the upper end of the upright, the pressure block and the upright can be pre-assembled and positioned, which facilitates the fastening of the pressure block and the upright by the second screws and improves the fixing firmness and reliability of the pressure block and the upright.

"Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0022] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0023] See Figure 1-5 As shown in the embodiment of this application, an aluminum alloy scooter frame is disclosed, including a footrest 1, a column 2, a front shock absorber plate 3, a folding lower seat 4, a folding upper seat 5, a handlebar 6, and a hollow upright 7. A support shaft 31 is provided at the top of the front end of the front shock absorber plate 3. A rotating sleeve 21 is provided at the front end of the column 2, and the rotating sleeve 21 is rotatably fitted onto the support shaft 31. The rear end of the column 2 is fixed to the front end of the footrest 1. The folding lower seat 4 is fixed to the upper end of the support shaft 31. The rear side of the folding upper seat 5 is rotatably connected to the rear side of the folding lower seat 4. The lower end of the upright 7 is fixed to the upper end of the folding upper seat 5. The handlebar 6 is fixed to the upper end of the upright 7. The aluminum alloy scooter frame also includes a locking assembly. The locking assembly is used to lock the lower folding seat 4 and the upper folding seat 5 to restrict the upper folding seat 5 from rotating freely relative to the lower folding seat 4. The locking assembly includes a hand-tightening bolt 8 and a "[" shaped clamping member 9. The screw part 81 of the hand-tightening bolt 8 passes through the clamping member 9 and is rotatably connected to the clamping member 9. The screw part 81 is threadedly connected to the front side of the lower folding seat 4. The front side of the lower folding seat 4 and the front side of the upper folding seat 5 are respectively provided with a first groove 41 and a second groove 51. When the hand-tightening bolt 8 is rotated so that the handle 82 of the hand-tightening bolt 8 pushes the clamping member 9 toward one side of the lower folding seat 4 and the upper folding seat 5, the two ends of the clamping member 9 are respectively engaged in the first groove 41 and the second groove 51 and lock the lower folding seat 4 and the upper folding seat 5.

[0024] When the upright and handlebars need to be folded relative to the footrest, tighten the hand-tightening bolt to move it away from the locking element. During this process, the locking element moves away from the lower and upper folding seats. Once the two ends of the locking element disengage from the first and second slots respectively, the locking of the lower and upper folding seats is released. At this point, the upper folding seat can rotate backward relative to the lower folding seat, thus folding the upright and handlebars relative to the footrest. When the scooter needs to be used normally, rotate the upright and handlebars relative to the footrest forward, and then turn the hand-tightening bolt to push the locking element towards the lower and upper folding seats. At this point, the two ends of the locking element can engage with the first and second slots respectively, thus locking the lower and upper folding seats, and locking the upright and handlebars.

[0025] The inner walls at both ends of the clamping member 9 gradually slope away from the clamping member 9 from front to back, forming wedge-shaped engaging portions 91. The two engaging portions 91 are respectively used to engage with the first slot 41 and the second slot 51. The shapes of the first slot 41 and the second slot 51 are adapted to the shapes of the engaging portions 91 at corresponding positions. With this structure, when the hand-tightening bolt is tightened to push the clamping member towards the lower and upper folding seats, the two wedge-shaped engaging portions can engage more easily. The first and second slots facilitate the engagement of the locking parts with the first and second slots. Since the shapes of the first and second slots are adapted to the shapes of the locking parts at corresponding positions, as the two wedge-shaped locking parts are gradually inserted into the first and second slots, a squeezing force is applied to the front side of the lower folding seat and the front side of the upper folding seat, causing them to move closer together. This allows the front side of the upper folding seat to more reliably abut against the front side of the lower folding seat and securely fasten together.

[0026] An annular protrusion 811 is provided on the outer wall of the screw part 81, and the annular protrusion 811 abuts against the inner wall of the clamping member 9. With this structure, under the action of the annular protrusion, since the annular protrusion abuts against the inner wall of the clamping member, when the hand-tightening bolt is turned to move the hand-tightening bolt away from the clamping member, the annular protrusion can push the clamping member so that the clamping member moves away from the lower folding seat and the upper folding seat along with the hand-tightening bolt, so that the clamping member disengages from the first and second slots and achieves the locking state of the lower folding seat and the upper folding seat. In addition, under the action of the annular protrusion, the clamping member can be prevented from axially disengaging from the screw part.

[0027] The front end of the screw part 81 is inserted into the handle 82 and fastened to the handle 82 by the pin 83; with this structure, the front end of the screw part can be reliably fastened to the handle by the action of the pin.

[0028] The rear side of the folding upper seat 5 is rotatably connected to the rear side of the folding lower seat 4 via a pivot 10; with this structure, the rear side of the folding upper seat can be reliably rotatably connected to the rear side of the folding lower seat via the pivot.

[0029] The lower end of the folding base 4 is provided with a slot 42, and the upper end of the support shaft 31 is inserted into the slot 42. The folding base 4 is fastened to the upper end of the support shaft 31 by bolts. With this structure, since the upper end of the support shaft is inserted into the slot, the folding base and the support shaft can be limited. Under the action of the bolts, the folding base can be reliably fastened to the support shaft.

[0030] The upper end of the folding upper seat 5 is provided with a first insert 52, which is inserted into the lower end of the upright 7. The lower end of the upright 7 is fastened to the first insert 52 by a number of first screws. With this structure, after the first insert is engaged with the lower end of the upright, the folding upper seat can achieve pre-assembly and positioning of the upright, which facilitates the fastening of the first screws to the folding upper seat and the upright, and improves the fixing firmness and reliability of the folding upper seat and the upright.

[0031] The upper end of the upright 7 is fixed with a lower pressure bracket 20, and an upper pressure bracket 30 is fixed to the lower pressure bracket 20 by a bolt assembly. The middle part of the directional handle 6 is pressed onto the lower pressure bracket 20 by the upper pressure bracket 30. Through the cooperation of the upper and lower pressure brackets, the directional handle can be reliably fixed to the upper end of the upright.

[0032] The lower end of the pressure block 20 is provided with a second insert 201, which is inserted into the upper end of the upright 7. The second insert 201 is fastened to the upper end of the upright 7 by a number of second screws. With this structure, after the second insert is inserted into the upper end of the upright, the pressure block and the upright can be pre-assembled and limited, which facilitates the fastening of the pressure block and the upright by the second screws and improves the fixing firmness and reliability of the pressure block and the upright.

[0033] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
