Description

Technical Field

[0001] This application relates to the field of column folding technology, and in particular to a column folding mechanism for a mobility scooter. Background Technology

[0002] With the increasing popularity of portable transportation tools such as electric scooters and folding bicycles, users have higher and higher requirements for vehicle portability and space utilization. As a key component that determines the folding performance of a vehicle, the structural design of the pole folding mechanism directly affects the convenience and reliability of use.

[0003] Existing folding methods often revolve around the following two limiting methods: one is to fix it by the cooperation of the pin and the hole. Although this method is simple in structure, it requires alignment with the hole during operation, resulting in a poor folding experience; the other relies on spring force to maintain the buckle engagement. This method is prone to accidental disengagement in a vibration environment, posing a safety hazard. Therefore, the purpose of this application is to provide a column folding mechanism that is simple to operate and stable.

[0004] The above content is only used to help understand the technical solution of this application and does not represent an admission that the above content is the closest prior art to this application. Summary of the Invention

[0005] Based on this, this application provides a pole folding mechanism for a mobility scooter to solve one of the aforementioned technical problems.

[0006] The technical solution adopted by this application to solve its technical problem is a folding pole mechanism for a mobility scooter, comprising: a lower support rod seat, on which a connecting plate and a rotating part are disposed opposite to each other; an upper support rod block, one side of which is rotatably connected to the rotating part; a limiting mechanism, including a rotating disk and a connecting disk that can rotate relative to each other, the rotating disk being limited to one side of the upper support rod block, the connecting disk being limited to the connecting plate; a sliding block that is radially slidable along the axis and a limiting block disposed at the axis and capable of driving the sliding block to slide by rotation within the rotating disk and the connecting disk; a driving lever, rotatably disposed on one side of the connecting plate and capable of driving the limiting block to rotate; when the sliding block is driven outward by the limiting block and presses against the inner peripheral wall of the connecting disk, the rotating disk and the connecting disk cannot rotate relative to each other.

[0007] In some embodiments, the limiting mechanism is provided with a square shaft block, which passes through the rotating disk and the connecting disk. The outer periphery of the square shaft block that cooperates with the rotating disk and the connecting disk is provided with a circular portion that can rotate around the axis of both. The limiting block is provided with a first square groove that cooperates with the square shaft block.

[0008] In some embodiments, a coil spring is provided inside the rotating disk, and the two ends of the coil spring are respectively connected to the rotating disk and the square shaft block.

[0009] In some embodiments, a second square groove is provided on the square shaft block, a square shaft is provided at the center of the drive lever, the square shaft is inserted into the second square groove, a first bushing is rotatably provided on the connecting plate, the square shaft can pass through the first bushing, a rotating block is provided on one side of the upper support block, the rotating block can rotate in the rotating part, and a second bushing is rotatably provided between the rotating block and the rotating part.

[0010] In some embodiments, a first limiting portion is provided on the outer periphery of the upper support block to limit the rotation direction of the upper support block.

[0011] In some embodiments, a first-level surface and a second-level surface are formed on the circumferential surface of the limiting block. The radial height of the first-level surface is greater than that of the second-level surface. The limiting block cooperates with the sliding block through the first-level surface and the second-level surface to enable the limiting mechanism to enter the locked state and the movable state, respectively.

[0014] In some embodiments, the upper support block is provided with a second positioning hole, and the rotating disk is provided with a second positioning post that cooperates with the second positioning hole.

[0015] In some embodiments, the inner surface of the rotating disk is formed with a second limiting portion that restricts the sliding block to slide only.

[0016] The beneficial effects of this application are as follows: the sliding block is driven by the limiting block to radially press against the inner wall of the connecting plate, and the limiting mechanism is locked by using friction. Compared with the traditional pin or buckle structure, it has stronger anti-vibration performance, avoids accidental unlocking, and improves the safety of use.

Detailed Implementation

[0026] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application. In addition, the technical solutions of various embodiments can be combined with each other, but this must be based on the ability of those of ordinary skill in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection of this application.

[0027] In the embodiments of this application, please refer to Figure 1-7As shown, this application provides a folding pole mechanism for a mobility scooter, mainly comprising: a lower support rod seat 1, on which a connecting plate 11 and a rotating part 12 are disposed opposite to each other; an upper support rod block 2, one side of which is rotatably connected to the rotating part 12; a limiting mechanism 3, including a rotating disk 31 and a connecting disk 32 that can rotate relative to each other, the rotating disk 31 being limited to one side of the upper support rod block 2, and the connecting disk 32 being limited to the connecting plate 11; a sliding block 33 that slides radially along the axis and a limiting block 34 disposed at the axis and capable of driving the sliding block 33 to slide by rotation are disposed within the rotating disk 31 and the connecting disk 32; a driving lever 4, rotatably disposed on one side of the connecting plate 11 and capable of driving the limiting block 34 to rotate; when the sliding block 33 is driven outward by the limiting block 34 and presses against the inner peripheral wall of the connecting disk 32, the rotating disk 31 and the connecting disk 32 cannot rotate relative to each other.

[0028] Specifically, under normal conditions, the drive structure limit block 34, which is in a locked state, always presses against the connecting plate 32, preventing the rotating plate 31 from moving with the connecting plate 32. When the drive lever 4 is turned, the limit block 34 can rotate, and the drive sliding block 33 rotates. When the drive block rotates, the limit block 34 moves towards the center, and the rotating plate 31 can rotate, allowing the upper support block 2 to fold or reset.

[0029] The following will continue to describe some preferred / improved embodiments based on the above embodiments. Any one of the following embodiments can be selected, or multiple embodiments can be combined.

[0030] Reference Figure 3 As shown, a square shaft block 35 is provided inside the limiting mechanism 3. The square shaft block 35 passes through the rotating disk 31 and the connecting disk 32. A circular part 351 that can rotate around the axis of the rotating disk 31 and the connecting disk 32 is provided on the outer periphery of the square shaft block 35 that cooperates with the rotating disk 31 and the connecting disk 32. A first square groove 341 that cooperates with the square shaft block 35 is provided on the limiting block 34. The square shaft block 35 passes through the rotating disk 31 and the connecting disk 32. Its circular part 351 allows the rotating disk 31 and the connecting disk 32 to rotate relative to each other, while the square part cooperates with the first square groove 341 of the limiting block 34 to ensure that the limiting block 34 can rotate synchronously with the drive lever 4.

[0031] Specifically, a coil spring 311 is provided inside the rotating disk 31. The two ends of the coil spring 311 are connected to the rotating disk 31 and the square shaft block 35, respectively. The coil spring 311 can provide a rebound force to help the driving structure quickly enter the locked state when the driving structure is unlocked.

[0032] Preferably, the square shaft block 35 has a second square groove 352, the drive lever 4 has a square shaft 41 at its center, the square shaft 41 is inserted into the second square groove 352, the connecting plate 11 has a first bushing 111 rotatably mounted on it, the square shaft 41 can pass through the first bushing 111, the upper support block 2 has a rotating block 21 on one side, the rotating block 21 can rotate within the rotating part 12, the rotating block 21 and the rotating part 12 have a second bushing 121 rotatably mounted between the rotating block 21 and the rotating part 12, the first bushing 111 and the second bushing 121 are respectively mounted on the connecting plate 11 and the rotating block 21 to ensure the stability of the rotation process.

[0033] Reference Figure 7 As shown, a first limiting part 22 is provided on the outer periphery of the upper support block 2 to limit the rotation direction of the upper support block 2. The first limiting part 22 on the outer periphery of the upper support block 2 is used to limit its rotation range, prevent the upright from being over-folded or unfolded, and ensure structural safety.

[0034] Reference Figure 3 As shown in Figure 5, a first stepped surface 342 and a second stepped surface 343 are formed on the circumferential surface of the limiting block 34. The radial height of the first stepped surface 342 is greater than that of the second stepped surface 343. The limiting block 34, through the first stepped surface 342 and the second stepped surface 343, respectively cooperates with the sliding block 33 to put the limiting mechanism 3 into a locked state and a movable state. The greater height of the first stepped surface 342 pushes the sliding block 33 to extend radially, putting the drive structure into a locked state; the smaller height of the second stepped surface 343 allows the sliding block 33 to retract, unlocking the drive structure and allowing it to rotate freely.

[0035] Preferably, to make unlocking the drive structure easier, there is a smooth transition between the first surface 342 and the second surface 343.

[0036] Reference Figure 6 As shown, the sliding block 33 is provided with a limiting post 331, and the connecting plate 32 is provided with a limiting plate 321. The limiting plate 321 has a movable groove 3211. The limiting post 331 can move within the movable groove 3211. The center of the limiting plate 321 has a third groove 3212. The square shaft block 35 can drive the limiting plate 321 to rotate synchronously. At the same time, the contour of the movable groove 3211 has a turning point to serve as a transition when the driving structure changes state, and can play a certain limiting role for the sliding block 33.

[0037] Reference Figure 3As shown in Figure 7, the connecting plate 11 has a first positioning hole 112, and the connecting disk 32 has a first positioning pin 322 that mates with the first positioning hole 112. The upper support block 2 has a second positioning hole 23, and the rotating disk 31 has a second positioning pin 312 that mates with the second positioning hole 23. This arrangement ensures that the connecting disk 32 and the connecting plate 11, and the rotating disk 31 and the upper support block 2 are accurately positioned during installation.

[0038] Specifically, the inner surface of the rotating disk 31 is formed with a second limiting part 313 that restricts the sliding block 33 to slide only in the radial direction, so as to avoid deflection or jamming and affect the limiting effect.

[0039] Preferably, to reduce dust entering the limiting mechanism 3, the drive structure further includes a connecting housing 36, and both the rotating disk 31 and the connecting disk 32 are rotatably disposed within the connecting housing 36.

[0040] Preferably, the side of the sliding block 33 that contacts the connecting plate 32 is provided with a wavy surface 332 to increase the frictional force limiting the sliding block.

[0041] Preferably, both the connector and the drive lever 4 are provided with a protective housing 5 that matches them.
