Detailed implementation manners

[0025] The following are specific embodiments of the present invention and, in conjunction with the accompanying drawings, further describe the technical solutions of the present invention, but the present invention is not limited to these embodiments.

[0026] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relative positional relationship and movement conditions between components in a certain specific posture (as shown in the accompanying drawings). If this specific posture changes, then the directional indications will also change accordingly.

[0027] As Figures 1-7 shown, a foldable scooter includes:

[0028] A handlebar 100, which includes two steering rods 101. A handle 102 is fixedly arranged at the first ends of the two steering rods 101, and separation parts are arranged at the second ends of the two steering rods 101;

[0029] A frame 200, on which a connecting member 201 is rotatably arranged. The separation part and the connecting member 201 are hinged, and a locking part 105 is arranged between the separation part and the connecting member 201, so that the handlebar 100 can be folded or unfolded relative to the frame 200.

[0030] In this embodiment, the handlebar 100 includes two steering rods 101. The handle 102 is connected to the first ends of the two steering rods 101. The second ends of the two steering rods 101 are respectively provided with separation parts which are hinged to the connection parts 206 on the vehicle frame 200. The two steering rods 101 can be folded or unfolded relative to the vehicle frame 200. By providing two steering rods 101, the service strength of the entire handlebar 100 can be increased, the stress on the handlebar 100 can be shared, and thus the service life of the scooter can be increased.

[0031] It is worth mentioning that a hinge shaft is inserted between the separation part and the connecting piece 201 to achieve the hinged rotation therebetween.

[0032] Further preferably, along the direction from the second end to the first end of the steering rod 101, the gap between the two steering rods 101 gradually decreases, so that a triangle is formed between the two steering rods 101 and the vehicle frame 200. By using the stability of the triangle, the connection stability between the two steering rods 101 and the vehicle frame 200 is further increased.

[0033] As a preference, the separation part is provided with a first abutting groove 104 with an opening at one end, and the connecting piece 201 is provided with a second abutting groove 202 with an opening at one end. When the handlebar 100 is in the unfolded state, the first abutting groove 104 and the second abutting groove 202 are communicated with each other to form an installation cavity 106. The locking part 105 is fixed in the installation cavity 106, and the opposite two side surfaces of the locking part 105 are respectively abutted against the groove wall of the first abutting groove 104 and the groove wall of the second abutting groove 202.

[0034] Specifically, along the length extension direction of the handlebar 100, the upper and lower groove walls of the first abutting groove 104 are both higher than the upper and lower groove walls of the second abutting groove 202 or the upper and lower groove walls of the first abutting groove 104 are both lower than the upper and lower groove walls of the second abutting groove 202, so that the spaces of the two abutting grooves are misaligned, and the opposite two side surfaces of the locking part 105 are respectively abutted against the groove wall of the first abutting groove 104 and the groove wall of the second abutting groove 202.

[0035] In this embodiment, during the process of inserting the locking part 105 into the installation cavity 106, the lower end surface of the locking part 105 presses against the lower groove wall of the first abutting groove 104, and the upper end surface of the locking part 105 presses against the upper end surface of the second abutting groove 202, which can provide firm reliability for the separation part and the connection part 206.

[0036] Specifically, along the length extension direction of the handlebar 100, the cross-sectional shapes of the first abutting groove 104, the second abutting groove 202 and the locking part 105 are trapezoidal.

[0037] In this embodiment, in order to ensure that there is an extrusion effect between the locking portion 105 and the groove walls of the first abutting groove 104 and the second abutting groove 202 when the locking portion 105 is fixed in the installation cavity 106, the cross-sectional shape of the locking portion 105 is set to be trapezoidal, and the bottom side length of the extending end of the locking portion 105 is shorter than the bottom side length of the outer end of the locking portion 105. Then, as the locking portion 105 extends, the two side surfaces of the locking portion 105 gradually abut against the groove walls of the first abutting groove 104 and the second abutting groove 202, and as the locking portion 105 extends, the extrusion force between the locking portion 105 and the groove walls gradually increases.

[0038] As Figure 6 shown, further preferably, it further includes a knob 107. A set screw 108 is fixedly arranged on the knob 107, and the locking portion 105 is rotatably connected to the first end of the set screw 108. The second end of the set screw 108 is provided with an external thread, and an internal thread is provided on the connecting member 201, so that the second end of the set screw 108 can be screwed with the connecting member 201, and the locking portion 105 is fixed in the installation cavity 106 under the extrusion action of the knob 107.

[0039] In this embodiment, the second end of the set screw 108 is threadedly connected to the connecting member 201. Then, as the knob 107 rotates, the knob 107 gradually moves towards the locking portion 105 and extrudes the locking portion 105 to extend into the installation cavity 106. As the knob 107 rotates, the extending distance of the locking portion 105 in the installation cavity 106 increases, and the extrusion force between the locking portion 105 and the groove walls increases.

[0040] It is worth mentioning that a limiting ring 109 is further arranged at the first end of the set screw 108. The set screw 108 passes through the locking portion 105 and is rotatably connected thereto. The limiting ring 109 and the knob 107 are respectively located at both ends of the locking portion 105, so that the locking portion 105 can move together with the knob 107.

[0041] As a preference, an insurance portion is further arranged between the separating portion and the connecting member 201. The insurance portion includes an insurance pin 110. A first insurance hole 111 is arranged on the separating portion, and a second insurance hole 203 is arranged on the connecting member 201. The insurance pin 110 passes through the first insurance hole 111 and the second insurance hole 203 to realize the stability of the relative position between the separating portion and the connecting member 201.

[0042] In this embodiment, in order to prevent the head 100 from rotating relative to the frame 200 due to the connection failure between the set screw 108 and the connecting member 201 during the driving of the scooter, an insurance part is added between the head 100 and the frame 200 to perform a secondary connection between the head 100 and the frame 200. Specifically, a first insurance hole 111 is provided on the separation part, a second locking hole is provided on the connecting member 201, and the insurance pin 110 passes through the first insurance hole 111 and the second insurance hole 203 to achieve the stability of the relative position between the separation part and the connecting member 201. When the head 100 needs to be folded, the insurance pin 110 also needs to be pulled out.

[0043] It is worth mentioning that the insurance pin 110 is an existing plug-in pin, and its end is provided with a retractable elastic bead.

[0044] It is worth mentioning that the two separation parts are located on both sides of the connecting member 201, so that one insurance pin 110 can fix the head 100 and the frame 200; however, in order to improve the strength of the head 100, it is preferably to integrally provide the two separation parts, and the connecting member 201 includes two connecting parts 206, and the two separation parts are located between the two connecting parts 206, so each separation part and the corresponding connecting part 206 are respectively fixed by an insurance pin 110.

[0045] Preferably, a folding locking groove 112 is provided on the separation part, and the distance length between the folding locking groove 112 and the rotation axis of the separation part is equal to the distance length between the first insurance hole 111 and the rotation axis of the separation part.

[0046] In this embodiment, after the head 100 is folded and stored, it is also necessary to ensure the stability of the relative position between the head 100 and the frame 200. Therefore, a folding locking groove 112 is provided on the separation part, the locking part 105 is disconnected, and the insurance pin 110 is pulled out, so that the head 100 can be folded relative to the frame 200. After the head 100 is folded, the insurance pin 110 can be inserted back into the corresponding second insurance hole 203, and the insurance pin 110 passes through the second insurance hole 203 and extends into the folding locking groove 112 to achieve the relative stability between the head 100 and the frame 200.

[0047] It is worth mentioning that the knob 107 is located on the front of the frame 200, and the two insurance pins 110 are respectively located on both sides of the frame 200.

[0048] Preferably, an unfolding limiting wall 204 is provided on the connecting member 201, and a first track block 113 is provided on the separating portion. When the faucet 100 unfolds from the folded state, the first track block 113 gradually moves towards the unfolding limiting wall 204 until the outer end surface of the first track block 113 abuts against the unfolding limiting wall 204. The existence of the unfolding limiting wall 204 can limit the unfolding position of the faucet 100, and after the track block on the faucet 100 abuts against the unfolding limiting wall 204, the relative position between the two can also be kept stable, facilitating the subsequent installation of the safety bolt 110 and the locking portion 105.

[0049] More preferably, a folding limiting wall 205 is provided on the connecting member 201, and a second track block 114 is provided on the separating portion. When the faucet 100 folds from the unfolded state, the track block gradually moves towards the folding limiting wall 205 until the outer end surface of the track block abuts against the folding limiting wall 205; the existence of the unfolding limiting wall 204 can limit the folding position of the faucet 100, and after the track block on the faucet 100 abuts against the folding limiting wall 205, the relative position between the two can also be kept stable, facilitating the subsequent insertion of the safety bolt 110 into the folding locking groove 112.

[0050] It is worth mentioning that a folding limiting wall 205 and an unfolding limiting wall 204 are provided on each connecting portion 206.

[0051] Specifically, the upper end of the connecting member 201 is connected to the faucet 100, and a shock absorption assembly is provided at the lower end of the connecting member 201 and connected to the wheel.
