Description

Technical Field

[0001] This utility model relates to the field of folding scooter technology, and in particular to a folding hanging ring structure and a folding vehicle using the structure. Background Technology

[0002] Most existing folding scooters on the market place the folding ring on the handlebars at the front. When folding the scooter, pull the ring to engage with the corresponding fixing point on the scooter. When unfolding the scooter, pull or press the ring to remove it from the fixing point, and then return the other parts to their normal working positions.

[0003] Conventional folding lever loops rely on springs for return. The component assembly structure design causes the folding lever loop to protrude outside the handlebars, further shortening the lifespan of the spring. The spring is prone to not springing back, affecting the user's operating experience. Utility Model Content

[0004] In response to the shortcomings of the existing production technology, the applicant provides a reasonably structured folding ring structure and a folding vehicle using this structure. The spring in the conventional structure is replaced with an elastic damping structure to extend the service life of the parts. Furthermore, the folding ring is designed as a simplified structure that can be embedded in the handlebars, solving the problems of high product cost and long installation time.

[0005] The technical solution adopted in this utility model is as follows: A folding hanging ring structure includes a torque-adjustable hanging ring, the torque of which is adjusted by a damping component built into the hinge end of the hanging ring, the deformation of which generates frictional resistance against the hinge structure.

[0006] As a further improvement to the above technical solution: The hinge end of the hanging ring has a shaft hole and a threaded hole communicating with the shaft hole; a rotating shaft passes through the shaft hole, and the damping component is filled in the threaded hole and abuts against the rotating shaft passing through the shaft hole.

[0007] The axis of the threaded hole is set at an angle with the axis of the shaft hole.

[0008] The damping components include: The elastic damper is placed in the threaded hole and abuts against the shaft. Adjust the set screw, engage it in the threaded hole, and apply a tightening force to the elastic damper pointing towards the shaft.

[0009] The elastic damping is configured as a sphere.

[0010] Adjusting the set screw applies a tightening force perpendicular to the rotating shaft to the elastic damping.

[0011] A folding vehicle having the aforementioned folding ring structure; the folding ring structure is embedded in the side wall of a vehicle component.

[0012] As a further improvement to the above technical solution: The handlebars have a groove for the handlebar head, and the swivel is hinged in the groove.

[0013] The groove depth of the handle head should be greater than or equal to the thickness of the hanging ring.

[0014] The beneficial effects of this utility model are as follows: Compared to conventional spring folding devices, this invention reduces the number of parts, extends service life, and provides reliable connection strength, thereby improving vehicle comfort and riding safety.

[0015] In this invention, the elastic element is an elastic damping ball. The deformation of the elastic damping ball is controlled by adjusting the set screw. In addition to playing the same elastic role as a spring, the degree of deformation of the elastic damping ball can be controlled by changing the axial displacement of the set screw, thereby changing the contact area between the ball and the rotating shaft. The greater the deformation, the greater the contact area between the ball and the rotating shaft, and the greater the friction. This changes the magnitude of the friction to adapt to various working conditions.

[0016] The hanging ring of this invention can be hidden within the outer contour of the handlebars, improving the product's integrity and riding safety. Attached Figure Description

[0022] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0023] like Figures 1-4As shown, the folding hanging ring structure of this embodiment includes a torque-adjustable hanging ring 3. The torque is adjusted by a damping component built into the hinge end of the hanging ring 3. The deformation of the damping component generates frictional resistance against the hinge structure.

[0024] The hinge end of the hanging ring 3 has a shaft hole 300 and a threaded hole 310 communicating with the shaft hole 300; a rotating shaft 2 passes through the shaft hole 300, and the damping component is filled in the threaded hole 310 and abuts against the rotating shaft 2 that passes through the shaft hole 300.

[0025] The angle between the axis of the threaded hole 310 and the axis of the shaft hole 300 is set.

[0026] The damping components include: The elastic damper 4 is placed in the threaded hole 310 and abuts against the rotating shaft 2. Adjust the set screw 5, which engages in the threaded hole 310, and apply a tightening force to the elastic damper 4 in the direction of the rotating shaft 2.

[0027] The elastic damping 4 is set as a sphere.

[0028] Adjust the set screw 5 to apply a tightening force perpendicular to the rotating shaft 2 to the elastic damper 4.

[0029] The folding vehicle of this embodiment has a folding hanging ring structure; the folding hanging ring structure is embedded in the side wall of the vehicle component.

[0030] A handlebar groove 110 is provided on the handlebar 1, and the hanging ring 3 is hinged in the handlebar groove 110.

[0031] The groove depth of the handle groove 110 is greater than or equal to the thickness of the hanging ring 3.

[0032] The specific structure and working principle of this application are as follows: This application provides a torque-adjustable hanging ring 3 that can rotate to be fully embedded within the handlebar 1. For example... Figure 1 As shown, the hanging ring 3 is an arm-shaped component of fixed length. One end of the hanging ring 3 is hinged to the handlebar 1, and the other end of the hanging ring 3 is hollowed out, as shown. Figure 3 and Figure 4 As shown, this is so that it can be connected and engaged with the hooks on the vehicle body.

[0033] The handlebar 1 has a bent structure, with one section being a vertical tube that connects to the stem, and the other section being a horizontal tube that forms an angle with the vertical tube. A handlebar groove 110 is formed on the side wall of the vertical tube. The shape of the handlebar groove 110 is adapted to the hanging ring 3. One end of the hanging ring 3 is hinged within the handlebar groove 110 and can rotate around the hinge point. When the hanging ring 3 is rotated to fully fit within the handlebar groove 110, the entire hanging ring 3 rests within the handlebar groove 110, without protruding from the vertical tube, preventing it from snagging clothing, bags, or other items, thus improving riding safety.

[0034] The hinge end of the hanging ring 3 has a shaft hole 300, and a corresponding through hole 100 is opened on the handlebar 1. The rotating shaft 2 passes through the through hole 100 and the shaft hole 300 to rotatably connect the hanging ring 3 to the handlebar 1.

[0035] At this time, the hanging ring 3 can rotate around the rotating shaft 2, but it lacks a limiting force. The key improvement of this application is how to provide a reliable and adjustable limiting force.

[0036] like Figure 1 and Figure 2 As shown, the hanging ring 3 is expanded on the side facing the handlebar 1, near the hinge end, and a threaded hole 310 is formed at the expansion. The orientation of the threaded hole 310 needs to meet the requirement that when the hanging ring 3 is lifted, the opening of the threaded hole 310 faces the operator, so that the operator can adjust the components inside the threaded hole 310.

[0037] An elastic damper 4 is placed inside the threaded hole 310. The reason for preferring a spherical damper is that its deformation is greater and more readily apparent. When the elastic damper 4 is not under external force and is in contact with the rotating shaft 2, the elastic damper 4 makes point contact with the rotating shaft 2. When the elastic damper 4 is under external force and is in contact with the rotating shaft 2, the greater the external force, the greater the deformation, the larger the area of ​​the elastic damper 4 against the rotating shaft 2, and the greater the friction between the elastic damper 4 and the rotating shaft 2. This allows for adjustment of the force required to actuate the hanging ring 3 by adjusting the magnitude of the external force acting on the elastic damper 4.

[0038] The elastic damper 4 can also be in the shape of a block, which also utilizes deformation to change frictional resistance. However, the spherical structure is less restricted in terms of orientation during installation, therefore, this application selects the spherical elastic damper 4 as the optimal choice.

[0039] The external force for tightening the elastic damper 4 is achieved by adjusting the set screw 5. After the elastic damper 4 is inserted into the threaded hole 310, the adjusting set screw 5 is inserted into the threaded hole 310 to lock the elastic damper 4, and the elastic damper 4 is rotated to the expected depth.

[0040] Adjusting the force required to turn the hanging ring 3 allows the hanging ring 3 and the rotating structure to be suitable for various groups of people.

[0041] For example, turning the adjusting screw 5 to a state of greater resistance is suitable for adult vehicles, as adults have greater hand strength and the greater torque can withstand the larger loads of adult vehicles.

[0042] Adjusting the top screw 5 to a state of lower resistance is suitable for light, lightweight vehicles for children, such as non-powered folding scooters made of plastic. Children have limited hand strength, and this method optimizes the user experience while meeting the limit requirements.

[0043] The service life of the elastic damper 4 has been tested and found to be longer than that of the spring. Furthermore, the adjusting screw 5 can be tightened further if the elastic damper 4 becomes loose, compensating for any loss of elastic force. Alternatively, when the elastic damper 4 ages, it facilitates replacement with an independently configured elastic damper 4.

[0044] The aforementioned folding hook structure can be applied to folding vehicles, including children's folding bikes, adult folding bikes, electric folding bikes, elderly mobility folding bikes, folding strollers, flatbed folding carts, and other types of vehicles. The folding hook structure is installed on the handlebars of different folding vehicles and connected to fixed points on the vehicle body.

[0045] The advantage of this application is that the torque of the hanging ring 3 is adjustable and the hanging ring 3 can be built into the handlebar 1. The elastic damping 4 improves the product's service life and safety.

[0046] The above description is an explanation of the present utility model and not a limitation thereof. The scope of the present utility model is defined by the claims. Within the protection scope of the present utility model, any form of modification may be made.
