Description

Technical Field

[0001] The utility model relates to the technical field of scooters, in particular to a folding device on an electric scooter. Background Art

[0002] It is known that a scooter is a new type of portable single-person means of transportation, which has the characteristics of energy conservation and environmental protection, and is also convenient and safe to use. Due to the numerous advantages of scooters, they are becoming more and more popular among people. As a key structure on the scooter, the folding device not only requires a stable structural design, but also needs to consider the simplicity of appearance and convenient operation. For existing folding devices, such as the folding device and foldable walking tool disclosed in the Chinese utility model patent with the authorization announcement number CN214776347U, at least one through hole is provided on the hook, and the hook is arranged at the upper end cover through at least one first hook screw. However, this kind of hook is specifically located at the overlapping part of the upper end cover and the vertical pipe. It is necessary for the installation holes of the two upper end covers and the vertical pipe to coincide in order to lock the hook through the hook screw. Moreover, this kind of hook is not firm after installation and is very likely to loosen and fall off during frequent use, thus bringing potential safety hazards to the normal use in the later stage. Therefore, improvements are urgently needed according to this situation. Content of the Utility Model

[0031] To make the objectives, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. However, it should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the scope of the present utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessarily confusing the concept of the present utility model.

[0032] Embodiment 1: Refer to Figures 1 to 11 , a folding device on an electric scooter, comprising a riser 1 and an upper end cap 2 provided on the riser 1. A lower end cap 3 is hinged to the upper end cap 2, and a handle 4 is hinged to the lower end cap 3. A latch structure 5 is provided between the handle 4 and the upper end cap 2. The latch structure 5 includes a latch assembly 51 provided on the handle 4 and a hook 52 provided on the upper end cap 2. The hook 52 is fixed to the end face of the upper end cap 2 by at least three fixing members 53, and the three fixing members 53 are arranged in a triangle on the end face of the upper end cap 2. The latch assembly 51 is hinged to the lower end cap 3. With this arrangement, the installation of the hook 52 is simpler, and at the same time, the hook 52 is more firmly installed, greatly improving the looseness and detachment problems that occur during frequent use in the prior art, being more conducive to improving the safety during later use, and greatly meeting the user's usage requirements. In this embodiment, five fixing members 53 are used, including the fixing members 53 at the three fulcrums of the triangle and the two fixing members 53 inside the enclosed triangle. This arrangement makes the connection stronger and more stable, being more conducive to meeting the usage requirements. The fixing member 53 is a screw or a bolt, which has a wide source and is easy to implement.

[0033] Embodiment 2: It can be described on the basis of Embodiment 1. As Figures 1 to 11As shown, the latch assembly 51 includes a hinge seat 511 provided on the lower end cover 3 and a connecting shaft 512 provided on the hinge seat 511. A torsion spring 513 is provided on the connecting shaft 512. A handle 4 is provided on the connecting shaft 512 outside the hinge seat 511. A latch 514 for latching with the hook 52 is provided on the connecting shaft 512 inside the hinge seat 511. A tightening bolt 515 for abutting against the connecting shaft 512 is provided on the latch 514. The torsion spring 513 is in contact with the latch 514. A push button 516 is provided on the handle 4. A return spring 517 is provided on the push button 516. This is conducive to the push button 516 being able to return after being pushed. And a control board 518 for locking the latch 514 is connected to the push button 516. The control board 518 and the push button 516 are tightly connected by a fixing screw 519. The control board 518 is located on the lower surface of the handle 4, while the push button 516 is located on the upper surface of the handle 4. When in use, when the handle 4 rotates to abut against the outer surface of the upper end cover 2, the latch 514 will latch on the hook 52. And when the push button 516 is released, the push button 516 moves forward under the restoration of the return spring 517. Since the control board 518 and the push button 516 are tightly connected by a fixing screw, the push button 516 will drive the control board 518 to also move forward until the control board 518 locks on the latch 514. This is conducive to the latch assembly 51 being firmly locked. And when unlocking is required, only need to push the push button 516 backward. Since the push button 516 will compress the return spring 517, the push button 516 will also push the control board 518 to move backward, causing the control board 518 to disengage from the latch 514. Then when the handle 4 is rotated away from the upper end cover 2, the unlocking state can be achieved, and the operation is extremely simple and convenient. In the present utility model, since only one connecting shaft 512 is used, the firmness is greatly enhanced, and it is also conducive to convenient installation. Further explanation, the connecting shaft 512 is an eccentric shaft, which is more conducive to convenient implementation. Even further explanation, both ends of the connecting shaft 512 are locked on the hinge seat 511 by locking parts. The locking parts are screws, which is convenient for implementation.

[0034] Embodiment 3: It can be described on the basis of Embodiment 1 or Embodiment 2. For example, Figures 1 to 11 As shown, the lower end cover 3 includes a main body 31. An installation hole 32 is opened in the middle of the main body 31. An axial notch 33 is axially opened in the main body 31. Convex blocks 34 are provided on the outer surface of the main body 31 of the axial notch 33. The convex blocks 34 are fixedly locked by at least three fastening bolts 35. In this embodiment, three fastening bolts 35 are used. Such a setting enables the installation hole 32 to be better installed with the outside.

[0035] The standard parts used in this application document can all be purchased from the market. For the specific connection methods of each part, conventional means such as bolts and rivets that are mature in the existing technology are adopted, and no specific description will be made here.

[0036] It should be noted that although the above embodiments have been described in this article, the patent protection scope of the present utility model is not limited thereby. Therefore, based on the innovative concept of the present utility model, any changes and modifications made to the embodiments described in this article, or equivalent structural or equivalent process transformations made by using the content of the specification and drawings of the present utility model, and directly or indirectly applying the above technical solutions to other related technical fields, are all included in the patent protection scope of the present utility model.
