Description

Technical Field

[0001] This utility model relates to the field of electric scooter technology, and in particular to a locking folding structure. Background Technology

[0002] Electric scooters, as a new type of short-distance transportation tool, are increasingly popular. Electric scooters have a pole between the handlebars and the frame; one end of the pole connects to the handlebars, and the other end folds up for portability. When unfolded, it is locked in place using a locking mechanism. Currently, most locking mechanisms on the market use a hook structure, consisting of a hook and a latch. The hook is located on one pole, and the latch is on the other. After one pole is rotated to the unfolded state, the latch and hook engage and rotate until they lock together. This type of locking mechanism not only protrudes, but during sudden braking, the inertia can cause the hook and latch to hit the protruding parts. Furthermore, after prolonged use, the locking mechanism may loosen due to the lack of a locking mechanism, resulting in an insecure lock and posing a safety hazard. Utility Model Content

[0003] The purpose of this utility model is to design a locking folding structure to overcome the shortcomings of the above-mentioned technology.

[0004] This utility model designs a locking and folding structure for connecting and folding the front wheel frame and the handle bar. It includes a base part and a connecting part. The base part is connected to the front wheel frame, and the connecting part is connected to the handle bar. The connecting part is hinged to the base part, and the connecting part can switch between the connected and folded positions by rotation.

[0005] It also includes a positioning part, which is hinged at the hinge point between the connecting part and the base part. The positioning part is provided with a hook at the position relative to the hinge point, and the base part is provided with a first positioning member. When the connecting part is in the connecting position, the hook and the first positioning member form a hook connection to realize the positioning between the connecting part and the base part.

[0006] It also includes a locking part, which includes a first insertion hole on the positioning part and a through hole on the connecting part. The through hole is connected to the first insertion hole. The locking part also includes a pin, which is inserted into the first insertion hole and the through hole to achieve locking after the connecting part and the base part are connected to each other.

[0007] Preferably, the locking part further includes a handle with an eccentric hole, such that the handle is eccentrically hinged at the hinge point. The portion of the positioning part located at the hinge point is fixedly connected to the handle. When the handle rotates around the hinge point, the handle drives the positioning part to move eccentrically. The positioning part has a second insertion hole, and the connecting part has a second positioning member. The second positioning member passes through the second insertion hole, and the first insertion hole and the second insertion hole are interconnected to form an elongated hole. When the handle drives the positioning part to move eccentrically, the positioning part is relatively displaced with the elongated hole through the second positioning member, so that the hook is in tension or unlocked.

[0008] Further optimization includes a base and a movable pin. The base is fixedly connected to the through hole and has an installation hole. The movable pin is movably inserted into the installation hole. The base has a recess at the installation hole, and the movable pin has a protrusion. The protrusion and the recess form a convex-concave fit. When the movable pin is inserted into the installation hole and forms a convex-concave fit, the end of the movable pin is inserted into the insertion hole to form a lock. When the movable pin is pulled out until the recess and the protrusion are separated and misaligned, the end of the movable pin separates from the insertion hole and the lock is released.

[0009] Further optimization involves the inner diameter of the first socket being smaller than that of the second socket, and correspondingly, the outer diameter of the end of the movable pin inserted into the first socket is smaller than the outer diameter of the portion of the second positioning member that passes through the second socket.

[0010] Further optimization is achieved, with both the first and second positioning components being shaft structures.

[0011] Further optimization involves the second positioning element and the first positioning element being parallel to each other and symmetrically distributed along the interface between the connecting part and the base part.

[0012] Preferably, the positioning part includes a hinge end, a connecting section, and a positioning end. The positioning part is connected to the hinge point via the hinge end, and the positioning end and the hinge end are transitionally connected via the connecting section. The first insertion hole, the second insertion hole, and the hook are located at the positioning end, with the hook located below the positioning end and the first insertion hole and the second insertion hole located above the positioning end.

[0013] Preferably, the connecting part has a first receiving groove and the base part has a second receiving groove. When the connecting part is in the connecting position, the first receiving groove and the second receiving groove together form a groove to accommodate the positioning part, and the outer side of the positioning part is flush with the connecting part and the base part.

[0014] This utility model also provides an electric scooter, including the above-mentioned locking and folding structure.

[0015] The technical advantage of this utility model is that the base part and the connecting part are hinged to each other, and a positioning part is hinged at the hinge point. The positioning part is provided with a hook, and the base part is provided with a first positioning element. When the connecting part rotates to align with the base part, the hook and the first positioning element form a hook connection. Then, the positioning part is moved by controlling the handle to tighten the hook connection and prevent the connecting part from loosening or being accidentally unlocked. Finally, a pin is inserted into the positioning part to limit and lock the positioning part, preventing the positioning part from being moved by accidentally touching the handle. Therefore, this utility model is not only simple in structure, but also makes the locking more stable and reliable by using the positioning part and the pin for double limiting.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0023] This utility model is used to realize the connection and folding between the front wheel frame 1 and the handle bar 2. It includes a base part 4 and a connecting part 3, which are distributed vertically. The base part 4 is connected to the front wheel frame 1, and the connecting part 3 is connected to the handle bar 2. The connecting part 3 and the base part 4 are hinged to each other to form a docking. The connecting part 3 can switch between the connected and folded positions by rotation, that is, the connecting part 3 rotates around the hinge point. In this embodiment, after the base part 4 and the connecting part 3 dock, they form a rod-shaped structure as a whole.

[0024] This utility model also includes a positioning part 5, which is hinged at the hinge point between the connecting part 3 and the base part 4. The positioning part 5 is provided with a hook 6 at the position of the hinge point. That is, one side of the positioning part 5 is fixedly connected to the connecting part 3, and the other side is provided with a hook 6. The positioning part 5 rotates with the connecting part 3 around the hinge point. The base part 4 is provided with a first positioning member 7. When the connecting part 3 rotates to the connecting position, the hook 6 is engaged with the first positioning member 7 and forms a hook with the first positioning member 7 to realize the positioning between the connecting part 3 and the base part 4, so that the connecting part 3 and the base part 4 are connected to each other.

[0025] This utility model also includes a locking part, which includes a first insertion hole 8 opened on the positioning part 5 and a through hole 9 opened on the outer peripheral wall of the connecting part 3. The through hole 9 and the first insertion hole 8 are interconnected. The locking part also includes a pin 10, which is inserted into the first insertion hole 8 and the through hole 9. The top end of the pin 10 passes through the through hole 9 and is inserted into the first insertion hole 8, thereby connecting the connecting part 3 and the base part 4 to form a lock, preventing the connecting part 3 from reversing and folding. When the pin 10 is inserted or removed, causing the pin 10 to leave the first insertion hole 8, the connecting part 3 and the base part 4 are unlocked, allowing the connecting part 3 to rotate relative to the base part 4 and fold.

[0026] Furthermore, the locking part also includes a handle 11. One end of the handle 11 has an eccentric hole 12, and the other end serves as a force-applying end. In this embodiment, the connecting part 3 and the base part 4 are hinged by a rotating shaft. The rotating shaft passes through the eccentric hole 12 of the handle 11, so that the handle 11 is hinged at the hinge point. The part of the positioning part 5 located at the hinge point is fixedly connected to the handle 11. When the handle 11 rotates around the hinge point, the handle 11 drives the positioning part 5 to move eccentrically. In addition, the positioning part 5 is provided with a second insertion hole 13, and the connecting part 3 is provided with a second positioning member 14. The second positioning member 14 passes through the second insertion hole 13, and the first insertion hole 8 and the second insertion hole 13 are interconnected. When the handle 11 moves the positioning part 5 eccentrically, the positioning part 5 is relatively displaced within the elongated hole via the second positioning member 14. That is, when the connecting part 3 is hooked onto the base part 4 via the positioning part 5, the handle 11 is moved up and down, causing the handle 11 to move the positioning part 5 backward, thereby putting the hook into a clamped state and achieving the hook positioning state. When the handle 11 is moved in the opposite direction, the handle 11 rotates and causes the positioning part 5 to move in the opposite direction, that is, to move the positioning part 5 forward, thereby causing the hook 6 to loosen from the clamped state, thus unlocking the hook. At this time, the connecting part 3 can rotate relative to the base part 4 to form a fold.

[0027] Furthermore, the pin 10 includes a base 101 and a movable pin 103. Both the base 101 and the movable pin 103 are cylindrical structures. The base 101 is fixedly connected to the through hole 9. An axial mounting hole is provided on the base 101. The movable pin 103 is movably inserted into and removed from the mounting hole, that is, the movable pin 103 is inserted into the mounting hole and can move axially back and forth along the mounting hole. The base 101 has a recess 102 at the mounting hole, that is, the exposed end of the base 101 forms a symmetrical or... The movable pin 103 has recesses 102 spaced apart, and protrusions 104 on it. When the movable pin 103 is inserted into the mounting hole and the protrusions 104 and the recesses 102 form a convex-concave fit, the end of the movable pin 103 is inserted into the insertion hole. At this time, the pin 10 locks the positioning part 5 to prevent the hook of the positioning part 5 from loosening. When the movable pin 103 is pulled out part of the hole and the recesses 102 and the protrusions 104 are separated and staggered, the end of the movable pin 103 is separated from the insertion hole, thereby releasing the lock.

[0028] Furthermore, the inner diameter of the first socket 8 is smaller than the inner diameter of the second socket 13. Correspondingly, the outer diameter of the end of the movable pin 103 inserted into the first socket 8 is smaller than the outer diameter of the portion of the second positioning member 14 that passes through the second socket 13, so that the second positioning member 14 will not move into the first socket 8 and interfere with the movable pin 103.

[0029] Furthermore, both the first positioning element 7 and the second positioning element 14 are shaft structures, that is, the first positioning element 7 and the second positioning element 14 can adopt a rotating shaft, or a pin, or a column or shaft structure such as a screw or bolt. This makes it easy for the hook 6 to hook with the first positioning element 7 and for the second positioning element 14 to move back and forth in the second insertion hole 13. This not only makes the structure simple and easy to implement, but also ensures a stable connection.

[0030] Furthermore, the second positioning member 14 and the first positioning member 7 are parallel to each other and symmetrically distributed along the interface between the connecting part 3 and the base part 4. The second positioning member 14 and the first positioning member 7 are located on the other side of the hinge point. The second positioning member 14 and the first positioning member 7 are distributed vertically along the axial direction of the rod-shaped structure, so that the hook and the second positioning member 14 are in vertical balance, which is beneficial to the stability of the hook.

[0031] Furthermore, the positioning part 5 includes a hinge end 51, a connecting section 52, and a positioning end 53. In this embodiment, the positioning part 5 is a block structure. The positioning part 5 is connected to the hinge point through the hinge end 51. The positioning end 53 and the hinge end 51 are connected by the connecting section 52. The connecting section 52 serves as a connecting arm structure. The first insertion hole 8, the second insertion hole 13, and the hook 6 are located on the positioning end 53. The hook 6 is located on the lower side of the positioning end 53, and the first insertion hole 8 and the second insertion hole 13 are located on the upper side of the positioning end 53. This ensures that the force on the positioning part 5 is in a balanced state, thereby improving the stability of the positioning part 5 after it is locked.

[0032] Furthermore, a first receiving groove 31 is provided on the connecting part 3, and a second receiving groove 41 is provided on the base part 4. That is, the first receiving groove 31 and the second receiving groove 41 are respectively located on the opposite surfaces of the connecting part 3 and the base part 4. When the connecting part 3 is in the connecting position, the first receiving groove 31 and the second receiving groove 41 together form a groove to accommodate the positioning part 5. The outer side of the positioning part 5 is flush with the connecting part 3 and the base part 4, so that the base part 4 and the connecting part 3 form a rod-shaped structure as a whole after docking, which will not cause the rod-shaped structure to be abrupt, and the overall sense and appearance are better.

[0033] This utility model also provides an electric scooter, which includes the above-mentioned locking and folding structure.

[0034] This utility model is not limited to the above-described preferred embodiments. Anyone can derive other forms of products under the guidance of this utility model. However, regardless of any changes made in their shape or structure, any technical solution that is the same as or similar to this application falls within the protection scope of this utility model.
