[0041] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0042] like Figure 1-Figure 3 As shown, the folding device according to an embodiment of the present invention includes a first folding seat 1, a second folding seat 2, a first locking assembly 3, a second locking assembly 4 and a reset member, the first folding seat 1 and the second folding seat 2 are arranged opposite to each other, the first folding seat 1 is located above the second folding seat 2, the lower end surface of the first folding seat 1 is opposite to the upper end surface of the second folding seat 2, and the first folding seat 1 and the second folding seat 2 are rotatably connected.

[0043] The first locking assembly 3 is rotatably connected to the second folding seat 2, and the first locking assembly 3 is rotatable between a first position and a second position. In the first position, the first locking assembly 3 presses the first folding seat 1 against the second folding seat 2 so that the first folding seat 1 and the second folding seat 2 cannot rotate relative to each other; in the second position, the first locking assembly 3 releases the first folding seat 1, and the first folding seat 1 can rotate relative to the second folding seat 2.

[0044] The second locking assembly 4 is connected to at least one of the first folding seat 1 and the first locking assembly 3 for clamping and releasing the first folding seat 1 and the first locking assembly 3. When the second locking assembly 4 clamps the first folding seat 1 and the first locking assembly 3, the first folding seat 1 and the second folding seat 2 cannot rotate relative to each other.

[0045] The reset member is connected to at least one of the first locking assembly 3 and the second locking assembly 4, and is used to reset the first locking assembly 3 after the first locking assembly 3 rotates from the first position to the second position, and / or reset the second locking assembly 4 after the second locking assembly 4 releases the first folding seat 1 and the first locking assembly 3. It can be understood that the reset member can drive the first locking assembly 3 and / or the second locking assembly 4 to reset, thereby realizing automatic locking of the folding device.

[0046] According to the folding device of the embodiment of the present invention, a two-stage locking method of a first locking component 3 and a second locking component 4 is provided, thereby improving the locking stability of the folding device and preventing locking failure caused by accidental touch or mechanical vibration, thereby effectively improving the reliability and safety of the folding device. In addition, automatic locking of the folding device is achieved by providing a reset member, thereby improving the user experience.

[0047] like Figure 1 As shown, in some embodiments, the first folding seat 1 includes a first body 11 and a first protrusion 12, and the first protrusion 12 protrudes outward from the periphery of the first body 11. Similarly, the second folding seat 2 includes a second body 21 and a second protrusion 22, and the second protrusion 22 protrudes outward from the periphery of the second body 21, the first protrusion 12 and the second protrusion 22 are arranged opposite to each other, and a first groove 121 is provided on a side of the first protrusion 12 away from the second protrusion 22.

[0048] Furthermore, the first locking assembly 3 is rotatably connected to the second protrusion 22. In the first position, at least a portion of the first locking assembly 3 is engaged in the first groove 121, so that the first locking assembly 3 presses the first folding seat 1 onto the second folding seat 2 through the first protrusion 12; in the second position, at least a portion of the first locking assembly 3 is away from the first groove 121, so that the first locking assembly 3 releases the first folding seat 1.

[0049] like Figure 2 As shown, specifically, the first locking assembly 3 includes an unlocking wrench 31 and a locking block 32, the unlocking wrench is rotatably connected to the second protrusion 22, the unlocking wrench 31 has a cavity, the locking block 32 is fitted in the cavity of the unlocking wrench 31, and the locking block 32 can move relative to the unlocking wrench 31 along the length direction of the unlocking wrench 31, so that the outer end of the locking block 32 is clamped in the first groove 121 at the first position and is away from the first groove 121 before the unlocking wrench 31 moves from the first position to the second position. It should be noted that the outer end of the locking block 32 refers to the end of the locking block 32 close to the first protrusion 12.

[0050] like Figure 4As shown, the locking block 32 can move along the length direction of the unlocking wrench 31. When the unlocking wrench 31 is in the first position, the locking block 32 can be engaged in the first groove 121 or away from the first groove 121. When the outer end of the locking block 32 is engaged in the first groove 121, the unlocking wrench 31 cannot move from the first position to the second position, that is, the unlocking wrench 31 is locked in the first position. Only after the locking block 32 is away from the first groove 121, the unlocking wrench 31 can move from the first position to the second position. Therefore, the locking block 32 plays the role of a safety lock, realizes the locking of the unlocking wrench 31, so that the first locking assembly 3 is locked in the first position, which can effectively prevent the unlocking failure caused by accidental touch.

[0051] like Figure 5-Figure 7 As shown, in some embodiments, a first protrusion 12 is provided on a side away from the second protrusion 22, the first protrusion 122 is spaced apart from the first body 11, and a first groove 121 is formed between the first protrusion 122 and the first body 11, that is, the first groove 121 is formed between the first protrusion 122 and the first body 11. A second groove 321 is provided at the outer end of the locking block 32, and the unlocking wrench 31 is adapted to move from the second position to the first position through the transition position, in which the first protrusion 122 is engaged in the second groove 321, and the first protrusion 122 is away from the second groove 321 in the first position, the second position, between the first position and the transition position, and between the second position and the transition position.

[0052] When the unlocking lever 31 is in the transition position, the first protrusion 122 is engaged in the second groove 321. At this time, the first folding seat 1 and the second folding seat 2 are in the first-level locking state, only the first locking component 3 is effective, and the second locking component 4 is not effective. The user can ride safely. After that, the user can continue to turn the unlocking lever 31 to move the unlocking lever 31 to the first position. At this time, the folding device is in the second-level locking state, the first locking component 3 and the second locking component 4 are effective at the same time, and the locking block 32 is effective to ensure that the folding device will not be opened due to accidental touch.

[0053] like Figure 8 and Fig. 9 As shown, in some embodiments, the first locking assembly 3 further includes an unlocking dial button 33, which is connected to the locking block 32. The unlocking dial button 33 is disposed on the unlocking wrench 31 and can move along the length direction of the unlocking wrench 31 to drive the locking block 32 to move in the cavity of the unlocking wrench 31. Specifically, the unlocking dial button 33 is located on the outside of the unlocking wrench 31, which is convenient for the user to operate. During use, the user only needs to manually turn the unlocking dial button 33 to adjust the relative position of the locking block 32 and the first groove 121, so as to lock or unlock the unlocking wrench 31.

[0054] like Figure 3 and Figure 8 As shown, in some embodiments, a mounting groove is provided on a side of the unlocking wrench 31 away from the first body 11, and the mounting groove is communicated with the inner cavity of the unlocking wrench 31. The locking block 32 has a second protrusion 322, and the second protrusion 322 is matched in the mounting groove. The reset member includes a reset spring 34, the reset spring 34 is arranged in the mounting groove, and the first end of the reset spring 34 is connected to the end of the second protrusion 322 away from the second folding seat 2, and the second end of the reset spring 34 is connected to the wall surface of the mounting groove. In other words, the locking block 32 has a second protrusion 322, and the second protrusion 322 is located in the mounting groove. The unlocking dial 33 is connected to the second protrusion 322, thereby driving the locking block 32 to move, and a reset spring 34 is provided between the second protrusion 322 and the wall surface of the mounting groove, so that the second protrusion has a force toward the first groove 121.

[0055] With such a configuration, the user can push the lock block 32 away from the first groove 121 through the unlocking dial button 33, and then rotate the unlocking wrench 31 from the first position to the second position to release the first folding seat 1. And when the user moves the unlocking wrench 31 from the second position to the first position, under the action of the return compression spring 34, the lock block 32 is automatically inserted into the first groove 121, locking the unlocking wrench 31 so that it cannot rotate.

[0056] like Figure 3 and Fig. 9 As shown, in some embodiments, the reset member also includes a reset torsion spring 35, which is provided at the connection between the unlocking wrench 31 and the second protrusion 22. The reset torsion spring 35 has a force to rotate the unlocking wrench 31 toward the first position. After the user moves the unlocking wrench 31 from the first position to the second position and folds the first folding seat 1 and the second folding seat 2 or makes them relative to each other, the unlocking wrench 31 can be automatically reset and moved from the second position to the transition position, thereby pressing the first folding seat 1 against the second folding seat 2. This can prevent the user from carelessly forgetting to reset the unlocking wrench 31, making the folding device more reliable.

[0057] like Fig.11 As shown, in some embodiments, the second locking assembly 4 is a connecting rod assembly 41, one end of the connecting rod assembly 41 is rotatably connected to the first folding seat 1, and the other end of the connecting rod assembly 41 is rotatably connected to the first locking assembly 3, and the connecting rod assembly 41, the first folding seat 1, the second folding seat 2, and the first locking assembly 3 are connected end to end in sequence to form a four-bar linkage.

[0058] In the second position, the length direction of the connecting rod assembly 41 forms an angle with the length direction of the first locking assembly 3. At this time, the four-bar linkage can rotate freely; in the first position, the length direction of the connecting rod assembly 41 is roughly parallel to the length direction of the first locking assembly 3. At this time, the four-bar linkage is in a locked state, and only the first locking assembly 3 can move to the second position, that is, move outward, and the remaining components cannot move or rotate. Moreover, since the first locking assembly 3 cannot move freely under the action of the locking block 32, the first locking assembly 3 and the second locking assembly 4 take effect at the same time, and the locking is stable and reliable.

[0059] In some embodiments, the second locking assembly 4 is a pressing member 42, which is connected to the first locking assembly 3, and the first folding seat 1 is provided with a positioning member 43. In the first position, the pressing member 42 is pressed against the side of the positioning member 43 away from the second folding seat 2 to clamp the first folding seat 1 and the first locking assembly 3. At this time, the first locking assembly 3 and the second locking assembly 4 are effective at the same time, and the second locking assembly 4, the first folding seat 1 and the first locking assembly 3 cannot move relative to each other. In the second position, the pressing member 42 is away from the positioning member 43 to release the first folding seat 1 and the first locking assembly 3. At this time, the first locking assembly 3 and the second locking assembly 4 are not effective, and the first folding seat 1 and the first locking assembly 3 can rotate freely.

[0060] Specifically, the pressing piece 42 is generally cylindrical, the positioning piece 43 is generally cylindrical, and the axial direction of the pressing piece 42 is perpendicular to the axial direction of the positioning piece 43. A flange is provided at one end of the pressing piece 42 away from the first locking assembly 3, and the flange can press against the positioning piece 43 and away from the positioning piece 43. The flange is stuck on the side of the positioning piece 43 close to the first body 11, and the flange can prevent the pressing piece 42 and the positioning piece 43 from slipping off, so as to achieve a better locking effect. The pressing piece 42 is preferably a bolt, and the bolt can be fine-tuned by rotation, so as to adjust the pressing margin between the pressing piece 42 and the positioning piece 43.

[0061] like Fig.12 As shown, a scooter according to another embodiment of the present invention comprises a folding device, a stand pipe 5 and a front fork stand pipe 6. The folding device is a folding device according to an embodiment of the present invention. The stand pipe 5 is connected to one end of the first folding seat 1 away from the second folding seat 2, and the front fork stand pipe 6 is connected to one end of the second folding seat 2 away from the first folding seat 1. The other end of the stand pipe 5 is used to install a handle, and the front fork stand pipe 6 is used to connect the front fork assembly and the frame 7.

[0064] Specifically, the first folding seat 1 and the second folding seat 2 are connected via the first rotating shaft 13, the first locking assembly 3 and the second folding seat 2 are connected via the second rotating shaft 23, the second locking assembly 4 is a connecting rod assembly 41, the connecting rod assembly 41 includes a connecting rod 413 and a third rotating shaft 411 and a fourth rotating shaft 412 located at both ends of the connecting rod 413, the connecting rod is connected to the first locking assembly 3 via the third rotating shaft 411, and the connecting rod is connected to the first folding seat 1 via the fourth rotating shaft 412.

[0065] The first folding seat 1 includes a first body 11 and a first protrusion 12, and the first protrusion 12 protrudes outward from the outer periphery of the first body 11. The second folding seat 2 includes a second body 21 and a second protrusion 22, and the second protrusion 22 protrudes outward from the outer periphery of the second body 21. The first protrusion 12 and the second protrusion 22 are arranged opposite to each other, and a first groove 121 is provided on a side of the first protrusion 12 away from the second protrusion 22.

[0066] like Figure 2 and Figure 8 As shown, the first locking assembly 3 includes an unlocking wrench 31, a locking block 32, an unlocking dial button 33, a reset compression spring 34 and a reset torsion spring 35. The unlocking wrench is rotatably connected to the second protrusion 22. The unlocking wrench 31 is rotatable between a first position and a second position. The unlocking wrench 31 has a cavity. The locking block 32 fits in the cavity of the unlocking wrench 31. The unlocking dial button 33 is arranged on the unlocking wrench 31 and is connected to the locking block 32. The unlocking dial button 33 drives the locking block 32 to move along the length direction of the unlocking wrench 31 so that the locking block 32 is close to or away from the first groove 121.

[0067] A mounting groove is provided on one side of the unlocking wrench 31 away from the first body 11, and the mounting groove is communicated with the inner cavity of the unlocking wrench 31. The locking block 32 has a second protrusion 322, and the second protrusion 322 is located in the mounting groove. The unlocking dial button 33 is connected to the second protrusion 322, thereby driving the locking block 32 to move. The reset spring is provided between the second protrusion 322 and the wall surface of the mounting groove, so that the second protrusion has a force toward the first groove 121. The reset torsion spring 35 is provided at the connection between the unlocking wrench 31 and the second protrusion 22, and the reset torsion spring 35 has a force to rotate the unlocking wrench 31 to the first position.

[0068] like Figure 6 and Figure 7As shown, a first protrusion 12 is provided on one side of the first protrusion 12 away from the second protrusion 22, and a first groove 121 is formed between the first protrusion 122 and the first body 11. A second groove 321 is provided at the outer end of the locking block 32, and the unlocking wrench 31 is adapted to move from the second position to the first position through the transition position. In the transition position, the first protrusion 122 is engaged in the second groove 321, at which time the first locking assembly 3 takes effect, and the folding device achieves primary locking.

[0069] The locking process and unlocking process of the folding device are described below.

[0070] The locking process: the unlocking lever 31 is in the second position, the folding device is in the folded state, and the user rotates the first folding seat 1 to change the folding device from the folded state to the upright state. During this process, the unlocking lever 31 automatically changes from the second position to the transition position under the action of the reset torsion spring 35, and the first protrusion 122 is clamped in the second groove 321, and the folding device achieves primary locking, that is, only the first locking component 3 is effective, and the second locking component 4 is not effective; thereafter, the user moves the unlocking lever 31 from the transition position to the first position by hand, and the outer end of the locking block 32 is automatically clamped in the first groove 121 under the action of the reset compression spring 34. At this time, the folding device achieves secondary locking, that is, the first locking component 3 and the second locking component 4 are effective at the same time, and the locking block 32 is clamped in the first groove 121, which can prevent the unlocking lever 31 from moving to the second position, thereby playing the role of a safety lock.

[0071] Unlocking process: the user turns the unlocking button 33, and the unlocking button 33 drives the locking block 32 away from the first groove 121. At this time, the locking block 32 fails. The user moves the first locking component 3 from the first position to the second position via the transition position. In the transition position, the first locking component 3 takes effect and the second locking component 4 fails. The folding device is locked at the first level. The user continues to move the unlocking wrench 31 to the second position, the first locking component 3 fails, and the folding device is unlocked.
