A handle and an eccentric wheel are fixedly connected to the rotatable shaft. A locking component is fitted on the eccentric wheel. The locking component includes a rotating arm and a locking block. The rotating arm is fitted on the eccentric wheel. A torsion spring for driving the rotating arm to rotate to a vertical position is fitted on the eccentric wheel.

[0005] The installation of the torsion spring in this patent is quite complicated, and the setting of the eccentric wheel not only makes it difficult to disassemble and assemble the torsion spring and the eccentric wheel, but also results in a large number of parts for the drive locking component, leading to more disassembly and assembly steps for the folder and severely reducing disassembly and assembly efficiency. Furthermore, the high cost of the torsion spring itself and the large number of parts in the folder increase the cost of the folder. Utility Model Content

[0030] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0031] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

[0032] This embodiment mainly describes a folding mechanism suitable for scooter handlebars that can reduce the number of parts and improve assembly / disassembly efficiency, as detailed below:

[0033] like Figure 1-7 As shown, a folding device suitable for scooter handlebar uprights includes a first connecting seat 1 for connecting scooter pedals and a second connecting seat 2 for connecting scooter handlebar uprights. The first connecting seat 1 and the second connecting seat 2 are rotatably connected. In this embodiment, a rotating shaft 3 is rotatably mounted on the first connecting seat 1, and an operating handle 4 is fixedly connected to the rotating shaft 3. A rotating locking member 5 is rotatably mounted on the rotating shaft 3, and a sliding locking member 6 is slidably mounted on the operating handle 4. The rotating locking member 5 is provided with a limiting part 5a and an action part 5b that deviate from the rotating shaft 3. The rotating shaft 3 is located between the limiting part 5a and the action part 5b. The sliding locking member 6 is provided with a limiting port 6a. The second connecting seat 2 is provided with a limiting rod 7 that can cooperate with the limiting port 6a of the sliding locking member 6 and a limiting rod 8 that can cooperate with the limiting part 5a of the rotating locking member 5. A spring or spring sheet 9 is installed between the first connecting seat 1 and the action part 5b of the rotating locking member 5. The spring or spring sheet 9 has elastic potential energy on the action part 5b of the rotating locking member 5.

[0034] The limiting port 6a of the sliding lock 6 cooperates with the limiting rod 7, and the limiting part 5a of the rotating lock 5 cooperates with the limiting rod 8, both of which can restrict the rotation of the first connecting seat 1 and the second connecting seat 2. When the limiting port 6a of the sliding lock 6 is disengaged from the limiting rod 7, rotating the operating handle 4 can cause the operating handle 4 to press against the action part 5b of the rotating lock 5, causing the rotating lock 5 to rotate and disengage from the limiting rod 8.

[0035] Preferably, when the operating handle 4 is not pressed against the actuating part 5b, the spring or spring sheet 9 can ensure that the rotating lock 5 remains in a vertical state, that is, the limiting part 5a of the rotating lock 5 can limit the limiting rod 8, restricting the rotation between the second connecting seat 2 and the first connecting seat 1.

[0036] To ensure the stable installation of the spring or spring piece 9, the first connecting seat 1 is provided with an installation groove 1a, and the actuating part 5b is provided with a limiting groove 5c. The spring or spring piece 9 is located between the bottom of the installation groove 1a and the bottom of the limiting groove 5c.

[0037] In this application, by rotating the rotating lock 5 and providing elastic support for the rotating lock 5 with a spring or spring plate 9, the number of accessories is effectively reduced while ensuring that the rotating lock 5 can restrict the rotation of the first connecting seat 1 and the second connecting seat 2. The use of a spring or spring plate 9 instead of a torsion spring can effectively reduce costs, reduce the difficulty of disassembly and assembly, and improve disassembly and assembly efficiency.

[0038] like Figure 2-7 As shown, the first connecting seat 1 is provided with an abutting surface 1b, and the second connecting seat 2 is provided with an abutting surface 2a that can fit with the abutting surface. When the sliding lock 6 or the rotating lock 5 restricts the rotation of the first connecting seat 1 and the second connecting seat 2, the abutting surface 1b fits with the abutting surface 2a.

[0039] In this embodiment, the first connecting seat 1 is provided with a plug 1d, which protrudes from the abutting surface 1b, while the second connecting seat 2 is provided with a recessed socket 2b relative to the abutting surface 2a. When the abutting surface 1b and the abutting surface 2a are in contact, the plug 1d can be inserted into the socket 2b. Preferably, due to the rotational connection between the first connecting seat 1 and the second connecting seat 2, there will be a slight relative wobbling between the vertical rotation axis of the first connecting seat 1 and the second connecting seat 2. The insertion and engagement of the plug 1d and the socket 2b can effectively limit the wobbling between the first connecting seat 1 and the second connecting seat 2.

[0040] like Figure 2-7As shown, the first connecting seat 1 is provided with two protruding rotating bosses 1c. The two ends of the rotating shaft 3 are rotatably connected to the rotating bosses 1c. An eccentric section 3a may be provided at the position between the two rotating bosses 1c. The axis of the eccentric section 3a is offset from the axis of rotation of the rotating shaft 3 on the rotating bosses 1c. The rotating lock 5 is rotatably connected to the eccentric section 3a, so that when the operating handle 4 is flipped up or down and does not press against the action part 5b of the rotating lock 5, the gap between the limiting part 5a of the rotating lock 5 and the limiting rod 8 can be adjusted. Preferably, the eccentric section 3a can be slightly bent on the rotating shaft 3, without affecting the insertion and installation of the rotating shaft 3 on the rotating shaft 3 boss.

[0041] In this embodiment, the rotating lock 5 is provided with a rotating connecting part 5d that is inserted into the rotating shaft 3, and an extension section 5e that connects to the rotating connecting part 5d. The function part 5b is also connected to the rotating connecting part 5d, and the rotating connecting part 5d is located between the extension section 5e and the function part 5b. The extension section 5e and the function part 5b have opposite orientations. The limiting part 5a is protruding from the end side wall of the extension section 5e. The limiting part 5a is provided with a pushing surface 5f. Preferably, the pushing surface 5f can be obliquely or arc-shaped.

[0042] When the first connecting seat 1 and the second connecting seat 2 are not limited by the sliding lock 6 and the rotating lock 5, the setting of the push-rotating surface 5f allows the second connecting seat 2 to rotate so that the limiting rod 8 on the second connecting seat 2 fits against the push-rotating surface 5f. By acting on the push-rotating surface 5f, the rotating lock 5 is pushed to deflect until the limiting part 5a of the rotating lock 5 is above the limiting rod. At this time, the rotating lock 5 can restrict the second connecting seat 2 from rotating away from the first connecting seat 1.

[0043] like Figure 2-7 As shown, the side wall of the second connecting seat 2 is provided with two protruding limiting bosses 2c and 2d. Limiting rod 7 is installed on the two limiting bosses 2c and limiting rod 8 is installed on the limiting boss 2d. Both limiting rod 7 and limiting rod 8 are offset from the side wall of the second connecting seat 2. When the abutting surface 1b of the first connecting seat 1 is in contact with the abutting surface 2a of the second connecting seat 2, the limiting boss 2d is located between the limiting boss 2c and the rotating boss 1c.

[0044] The operating handle 4 has a central part 4a and side wings 4b located on both sides of the central part 4a. The operating handle 4 is connected to the rotating shaft 3 through the side wings 4b. The central part 4a has an installation port 4c at the position of the rotating shaft 3. The sliding lock 6 has a sliding operating part 6b that can cover the installation port 4c and an action section 6c that inserts into the installation port 4c. The action section 6c has a sliding groove 6d that slides to connect with the side wall of the installation port 4c and a limiting port 6a that can be inserted and cooperated with the limiting rod 7. The outer dimension of the sliding operating part 6b is larger than that of the installation port 4c, and the dimension of the action section 6c is smaller than that of the inner dimension of the installation port 4c. An installation cavity 10 is formed between the side wall of the installation port 4c and the action section 6c. A support spring 11 for the elastic sliding lock 6 is installed in the installation cavity 10.

[0045] Preferably, when the sliding lock 6 is engaged with the limiting rod 7 for limiting, the rotating boss 1c on the first connecting seat 1, the limiting boss 2c on the second connecting seat 2, and the limiting boss 2d on the second connecting seat 2 are all located between the two side wings 4b, which can effectively improve the uniformity of the folding device operating handle 4 and enhance its aesthetics.

[0046] To prevent the support spring 11 from falling out of the mounting cavity 10, a limiting member 12 is threaded onto the actuating section 6c. The support spring 11 is located between the limiting member 12 and the sliding operating part 6b. The limiting member 12 and the sliding operating part 6b can prevent the support spring 11 from leaving the mounting cavity 10.

[0047] The sliding lock 6 has a push-sliding surface 6e on its working section 6c. When the sliding lock 6 on the operating handle 4 is not in a limiting engagement with the limiting rod 7, the abutting surface 1b of the first connecting seat 1 is in contact with the abutting surface 2a of the second connecting seat 2. At this time, the rotating lock 5 engages with the limiting rod 8, and the operating handle 4 rotates toward the second connecting seat 2, so that the push-sliding surface 6e of the sliding lock 6 on the operating handle 4 is in contact with the limiting rod 7. If the operating handle 4 continues to rotate, the second connecting seat 2 is not easy to deflect under the restriction of the rotating lock 5. The limiting rod 7 on the second connecting seat 2 drives the sliding lock 6 to slide by acting on the push-sliding surface 6e. The working section 6c of the sliding lock 6 compresses the support spring 11 until the limiting port 6a on the sliding lock 6 is aligned with the limiting rod 7. Under the elastic action of the support spring 11, the limiting port 6a of the sliding lock 6 is engaged with the limiting rod 7.

[0048] In this embodiment, a limiting connection part 4d protrudes from the middle part 4a of the operating handle 4. The protruding direction of the limiting connection part 4d is consistent with the direction of the side wing 4b. A limiting connector 13 is detachably installed on the limiting connection part 4d. The limiting connector 13 can be threaded onto the limiting connection part 4d. A limiting rod 14 is installed on the limiting boss 2d. Rotating the operating handle 4 causes the end of the limiting connector 13 to rub against the side wall of the limiting rod 14. The fit between the limiting connector 13 and the limiting rod 14 can clearly limit the rotation of the first connecting seat 1 and the second connecting seat 2, ensuring the stability of the rotation restriction of the first connecting seat 1 and the second connecting seat 2 by the sliding lock 6, the rotating lock 5, and the limiting connector 13.

[0049] Preferably, the threaded connection of the limiting connector 13 allows for adjustment of the frictional force between the end of the limiting connector 13 and the side wall of the limiting rod 14, or, after the end of the limiting connector 13 is worn, the threaded adjustment of the limiting connector 13 ensures the frictional force between the end of the limiting connector 13 and the side wall of the limiting rod 14.

[0050] The entire locking process only requires rotating the second connecting seat 2 to achieve the locking engagement between the rotating locking piece 5 and the limiting rod 2 8, and then rotating the operating handle 4 to achieve the end of the limiting connecting piece 13 to fit against the side wall of the limiting rod 3 14, and the sliding locking piece 6 to achieve the limiting engagement with the limiting rod 1 7. The locking can be achieved in two steps, which is simple and convenient to operate.

[0051] The specific steps and the gradual interaction between the various components during the unlocking process are as follows.

[0052] Step 1: As Figure 4 As shown, the sliding operation of the sliding lock 6 compresses the spring, and the limiting port 6a on the sliding lock 6 disengages from the limiting rod 7. At this time, the end of the limiting connector 13 is tightly fitted with the side wall of the limiting rod 14. Preferably, the tight fit between the limiting connector 13 and the limiting rod 14 makes it difficult for the operating handle 4 to rotate without being subjected to external force when the sliding lock 6 is accidentally slid and the operating handle 4 is not rotated.

[0053] Step Two: As Figure 4-5 As shown, with the limiting port 6a on the sliding lock 6 disengaged from the limiting rod 7, the operating handle 4 is rotated outward until the end of the limiting connector 13 is far away from the side wall of the limiting rod 14 and the operating handle 4 contacts the action part 5b of the rotating lock 5. At this time, the operating handle 4 will rotate due to shaking or bumping, but the rotation angle is limited by the limiting connector 13 and the rotating lock 5.

[0054] Step 3: As Figure 6As shown, the operating handle 4 is rotated continuously, and the operating handle 4 presses against the working part 5b of the rotating lock 5. The rotating lock 5 rotates under the pressure of the operating handle 4, causing the limiting part 5a of the rotating lock 5 to rotate away from the limiting rod 8, and the working part 5b of the rotating lock 5 to compress the support spring 11.

[0055] Step Four: As Figure 7 As shown, rotating the second connecting seat 2 causes the contact surface 2a of the second connecting seat 2 to deviate from the contact surface 1b of the first connecting seat 1, thereby realizing the folding of the pole when the folding device is used on the scooter.
