Description

Technical Field

[0001] This utility model relates to the field of scooter technology, and in particular to a novel double-lock mechanism for scooters. Background Technology

[0002] Scooters are a mode of transportation. New regulations require scooters to have a second safety lock mechanism to further ensure user safety. Common folding mechanisms are widely used in scooters and electric scooters, but they lack a second safety lock. Without this second lock, there is a risk that the folding mechanism may detach during riding. Currently available second-lock solutions require the user to manually unlock the safety lock before folding the scooter. Once unlocked, the safety lock remains open and does not automatically close or lock when the scooter is unfolded. This means that users must remember to manually lock the second safety lock after unfolding the vehicle. If users forget to manually close the second safety lock, it will remain open. After unfolding the vehicle, users can directly fold or unfold it, rendering the second safety lock ineffective and greatly increasing the risk of the locking shaft falling off. This also does not comply with the new regulations. Furthermore, users need to perform the operation in three steps: manually opening the second safety lock → folding the vehicle → manually closing the second safety lock to complete the entire process. The process is cumbersome and the step of closing the safety lock is easy to forget. Utility Model Content

[0003] In view of the above-mentioned problems in the prior art, the main objective of this utility model is to provide a novel dual-protection lock mechanism for scooters.

[0004] The technical solution of this utility model is as follows: a novel double-lock mechanism for scooters includes a housing, a fixed rotating shaft on the housing, a locking shaft on one side of the fixed rotating shaft, the fixed rotating shaft being connected to the locking shaft via a square tube tension spring, a U-shaped double lock on the fixed rotating shaft, a pedal torsion spring on the fixed rotating shaft, one end of the pedal torsion spring being connected to the U-shaped double lock, and a pedal structure inside the housing.

[0005] In a preferred embodiment, the pedal structure includes a double-lock activated pedal and a folding pedal. The double-lock activated pedal is connected to the folding pedal via a pedal pin, which is fixedly connected to the outer shell. A pedal tension spring is provided on one side of the double-lock activated pedal, with one end of the pedal tension spring fixedly connected to the double-lock activated pedal and the other end fixedly connected to the folding pedal.

[0006] In a preferred embodiment, the double-lock activation pedal has a through groove, a retaining edge on one side of the through groove, the folding pedal includes a slot, a spring connecting seat on one side of the slot, a rotating hole directly above the slot, a wrench above the rotating hole, a limiting protrusion on the side of the rotating hole, and the wrench passes through the through groove of the double-lock activation pedal.

[0007] In a preferred embodiment, the double-lock activation pedal has a rotation space, a spring connecting through hole on one side of the rotation space, a retaining edge on one side of the double-lock activation pedal, a slot, a spring connecting seat on one side of the slot, a rotation hole directly above the slot, a limiting protrusion above the rotation hole, and the folding pedal is located within the rotation space of the double-lock activation pedal.

[0008] In a preferred embodiment, the U-shaped double lock includes a fixed rotating shaft hole, a locking shaft groove on one side of the fixed rotating shaft hole, and an arc-shaped track on the upper side of the locking shaft groove.

[0009] Compared with the prior art, the advantages and positive effects of this utility model are that it adds a safety mechanism to the structure that restricts the sliding direction of the locking shaft, and makes this component have an automatic locking protection function. Only by manually pressing the double lock to activate the pedal to the designated position and keeping it pressed for a long time can the locking shaft slide upward. If it stops or is released midway, the protection mechanism will automatically lock and activate the function of restricting the sliding of the locking shaft. Attached Figure Description

[0030] Example

[0031] A novel double-locking mechanism for scooters includes a housing 1, a fixed rotating shaft 2 on the housing 1, a locking shaft 3 on one side of the fixed rotating shaft 2, the fixed rotating shaft 2 being connected to the locking shaft 3 via a square tube tension spring 4, a U-shaped double lock 5 on the fixed rotating shaft 2, and a pedal torsion spring 6 on the fixed rotating shaft 2, one end of which is connected to the U-shaped double lock 5. A pedal structure 7 is located inside the housing 1. When folding, two actions are required: the first action, which requires keeping the U-shaped double lock 5 in the open state, allows the second action—the locking shaft 3 sliding out of the locking shaft slot 52—to fold the scooter. If the first action is stopped midway, the U-shaped double lock 5 will automatically lock again, preventing the scooter from unfolding further. When unfolding the scooter, only one action is needed to automatically engage the locking shaft 3 in the locking shaft slot 52, causing the U-shaped double lock 5 to automatically lock and lock the locking shaft 3, preventing it from popping out.

[0032] The pedal structure 7 includes a double-lock activation pedal 71 and a folding pedal 72. The double-lock activation pedal 71 is connected to the folding pedal 72 via a pedal pin 73. The pedal pin 73 is fixedly connected to the outer shell 1. A pedal tension spring 74 is provided on one side of the double-lock activation pedal 71. One end of the pedal tension spring 74 is fixedly connected to the double-lock activation pedal 71, and the other end is fixedly connected to the folding pedal 72. When the double-lock activation pedal 71 is pressed, it will contact the U-shaped double lock 5, causing one side of the U-shaped double lock 5 to move downward. The locking shaft 3 slides out of the locking shaft slot 52 of the U-shaped double lock 5. At this time, the folding pedal 72 is driven, pulling the locking shaft 3 to move, thereby unlocking.

[0033] The double-lock activation pedal 71 has a through groove 711, and a retaining edge 712 is provided on one side of the through groove 711. The folding pedal 72 includes a slot 721, a spring connecting seat 722 is provided on one side of the slot 721, a rotating hole is provided directly above the slot 721, a wrench 724 is provided above the rotating hole, and a limiting protrusion 723 is provided on the side of the rotating hole. The wrench 724 passes through the through groove 711 of the double-lock activation pedal 71. This is the first type of folding pedal 72 structure, which can expose the wrench 724 on the outside of the double-lock activation pedal 71, making it easy for the user to observe and activate the double-lock function.

[0034] The double-lock activation pedal 71 has a rotation space 713. A spring connecting through hole 714 is provided on one side of the rotation space 713. A stop edge 712 is provided on one side of the double-lock activation pedal 71. The folding pedal 72 includes a slot 721. A spring connecting seat 722 is provided on one side of the slot 721. A rotation hole is provided directly above the slot 721. A limiting protrusion 723 is provided above the rotation hole. The folding pedal 72 is located in the rotation space 713 of the double-lock activation pedal 71. This is the second type of folding pedal 72 structure. The folding pedal 72 can be hidden inside the double-lock activation pedal 71 and does not serve as a warning to the user. This can effectively avoid the user's wishful thinking and ensure the completion of the double-lock function.

[0035] The U-shaped double lock 5 includes a fixed rotating shaft hole 51, a locking shaft groove 52 on one side of the fixed rotating shaft hole 51, and an arc track 53 on one side above the locking shaft groove 52.

[0036] When folding is required, press the pedal structure 7. During the pressing process, a free travel segment is encountered. The free travel refers to a section of free rotation between the double-lock activation pedal 71 and the wrench 724; that is, before pushing the locking shaft 3 out, the double-lock activation pedal 71 is rotating, while the wrench 724 is not rotating. The key function of this free travel segment is to disengage the safety before pushing the locking shaft 3 out (while the double-lock activation pedal 71 is rotating and the wrench 724 is not rotating); after reaching the specified limit angle, the double-lock activation pedal 71 and the wrench 724 rotate together, pushing the locking shaft 3 out of the slot 721, allowing the U-shaped double-lock 5's locking shaft slot 52 to exit. When the locking shaft 3 rotates out, and the double-lock activation pedal 71 touches the folding pedal 72, since the locking shaft groove 52 of the U-shaped double-lock 5 has rotated out from the locking shaft 3, it no longer restricts the upward sliding of the locking shaft 3. Keep this action and continue to press down. Under the action of the double-lock activation pedal 71 touching the folding pedal 72, the locking shaft 3 slides out from the locking shaft groove 52, completing the folding. During the process of the double-lock activation pedal 71 touching the folding pedal 72, the double-lock activation pedal 71 is always in contact with the upper surface of the U-shaped double-lock 5, so that the U-shaped double-lock 5 rotates downward through the fixed rotating shaft 2, thereby achieving the purpose of opening the double-lock safety.

[0037] The second folding action is triggered only after the double-lock activation pedal 71 and the folding pedal 72 overlap. Therefore, they need to continue rotating together until the locking shaft 3 is pushed out of the locking shaft slot 52. After the U-shaped double lock 5 is opened, when the double-lock activation pedal 71 continues to rotate, the arc track 54 on the U-shaped double lock 5 allows the U-shaped double lock 5 to remain in the same position as the double-lock activation pedal 71 after it is opened, and also prevents the U-shaped double lock 5 from springing back on its own. The end of the double-lock activation pedal 71 away from the pedal tension spring 74 has a protrusion. By cooperating with the folding pedal 72 and the protrusion, and after being assembled by the pedal pin, the rotation angle is limited. The folding pedal 72 is a single-pedal mode, which can be divided into manual pedal and foot pedal. Both can share a single folding pedal and be interchangeable. That is, the user can choose different folding methods according to their preference - foot-operated rotation or manual pull-operated rotation activation.

[0038] Working principle:

[0039] When folding: The user presses or steps down the double lock activation pedal 71 with their hand or foot and touches the folding pedal 72. If this action is not released, the U-shaped double lock 5 is opened. If the user continues to press down, the locking shaft 3 will slide out from the locking position under the action of the double lock activation pedal 71 and the folding pedal 72, thus completing the folding.

[0040] When unfolded: This solution provides two unfolding options.

[0041] The first type: After the vehicle body is folded, the locking shaft 3 does not need to return to its original position, and the U-shaped double lock 5 is always in the open state;

[0042] When unfolded, the locking shaft 3 slides into the opening slot, and the U-shaped double lock 5 automatically locks, achieving double lock protection.

[0043] The second method: After the vehicle body is folded, the locking shaft 3 returns to its original position, and the U-shaped double lock 5 automatically locks and is in the closed state;

[0044] At this time, the U-shaped double lock 5 will add a function of locking the vehicle after folding. That is, no other locking mechanism is needed. The vehicle body cannot be unfolded by relying on the mechanism of the U-shaped double lock 5. When it is necessary to unfold, after pressing the double lock activation pedal 71, the U-shaped double lock 5 will open and continue to unfold. After the locking shaft 3 slides into the locking shaft slot 52, the U-shaped double lock 5 will automatically lock, realizing double lock protection.

[0045] Finally, it should be noted that the above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
