Description

Technical Field

[0001] This utility model relates to the field of electric vehicle accessories technology, specifically to a handlebar structure with integrated turn signals and an electric vehicle including the handlebar, which is particularly suitable for short-distance transportation tools such as electric scooters and electric bicycles. Background Technology

[0002] In existing portable transportation tools such as electric scooters and folding bicycles, handlebars are typically designed to be foldable for easy storage and carrying. Traditional folding handlebars are implemented in two main ways: one is by using a damping structure at the connection between the handlebar and the frame, utilizing friction to maintain the folded state; the other is by adding a mechanical lock at the pivot point, which is manually operated to lock the folded handlebar. However, these methods lack stability. The damping structure is prone to frictional attenuation due to long-term use or vibration, causing the folded handlebar to loosen or even unfold unexpectedly, posing a safety hazard. Furthermore, the locking mechanism is unreliable; the pivot lock relies on a single locking point, making it susceptible to disengagement during transportation or bumpy rides, generating noise, and it's difficult to guarantee a long-term reliable locking effect. Therefore, there is an urgent need for a handlebar folding locking solution that can achieve stable locking in the folded state and prevent loosening. Utility Model Content

[0003] The purpose of this utility model is to provide a handlebar folding locking device and an electric vehicle. Based on the connection between the foldable handlebar body and the vehicle body, a connecting structure is set on the handlebar body and cooperates with the locking component integrated in the insertion window of the vehicle body to form a plug-in mechanical lock. This ensures that the buckle position and the locking end are firmly engaged after the handlebar is folded, effectively resisting vibration and impact, while reducing noise problems caused by friction or gaps, and significantly improving the stability of the folded state and the user experience.

[0004] To achieve the above objective, a handlebar folding locking device includes:

[0005] The vehicle body has a connector window on its top.

[0006] The handlebars include a foldable handlebar body and a connecting structure disposed on the handlebar body.

[0007] A locking component is disposed within the insertion window. When the handlebar body is folded, one end of the connecting structure can be inserted into the insertion window; the locking end of the locking component can be snapped together with one end of the connecting structure.

[0008] The connection structure includes:

[0009] The connecting body has one end rotatably connected to the handlebar body; the other end of the connecting body is provided with a latching position that matches the latching end of the locking component; when the handlebar body is not fully folded, the other end of the connecting body can rotate around the one end of the connecting body under the action of an external force, so that the latching position can be aligned with the latching end of the locking component, and when the handlebar body is fully folded, the latching position engages with the latching end of the locking component;

[0010] The hook portion provided on the main body of the connector is used to hook onto external objects.

[0011] Furthermore, as a more preferred embodiment of this utility model, the hook portion is disposed in the middle of the side of the connector body facing the vehicle body; the other end of the connector body is rotated so that the hook portion abuts against the vehicle body, at which time the buckle position corresponds to the position of the insertion window, so that the buckle position can be positioned and inserted into the insertion window.

[0012] Furthermore, as a more preferred embodiment of this utility model, a magnetic window is provided at the other end of the connector body; the connection structure also includes a magnetic element, which is disposed at the magnetic window and can be attracted to the surface of the handlebar body. Under the action of external force, it can overcome the magnetic attraction and drive the other end of the connector body away from the handlebar body.

[0013] Furthermore, as a more preferred embodiment of this utility model, the handlebar body is provided with a receiving window; the top of the connector body is provided with a stepped portion, the stepped portion is adapted to the receiving window, the top two sides of the stepped portion are connected to the two sides of the receiving window through a pivot, and the stepped portion is disposed within the receiving window.

[0014] Furthermore, in a more preferred embodiment of this utility model, the locking component includes:

[0015] The housing is provided with sliding holes and unlocking windows;

[0016] A telescopic rod is installed inside the housing, one end of which is the locking end, which can pass through the sliding hole and move along the sliding hole;

[0017] An elastic element is disposed inside the housing, with one end abutting against the other end of the telescopic rod and the other end abutting against the inner wall of the housing;

[0018] Furthermore, as a more preferred embodiment of this utility model, the locking component further includes a movable unlocking component, which is disposed within the unlocking window and can slide along the unlocking window. Guide grooves are respectively provided on both sides of the movable unlocking component, and a guide rod is provided in the middle of the telescopic rod. The guide rods extend to the guide grooves on both sides of the movable unlocking component and can slide along the guide grooves. The guide grooves are inclined. The movable unlocking component can be driven by an external force to slide along the unlocking window, and the guide rods can slide along the guide grooves, causing the locking end to retract, thereby limiting the locking position.

[0019] Furthermore, as a more preferred embodiment of this utility model, the cross-section of the movable unfastening member is a U-shaped structure, and the guide grooves are provided on both side walls of the U-shaped structure. The guide grooves are inclined relative to the telescopic rod, and the displacement of the guide grooves can drive the guide rod to slide to one side of the elastic member, thereby causing the telescopic rod to compress the elastic member axially.

[0020] Furthermore, as a more preferred embodiment of this utility model, a guide ramp is provided on the side of the locking end facing the insertion window. When the other end of the connector body is pushed into the insertion window along the guide ramp, it can drive one end of the telescopic rod to retract until the other end of the connector body can be fully inserted into the insertion window. Under the action of the restoring force of the elastic element, one end of the telescopic rod pushes one end of the telescopic rod into the buckle position to achieve the locking state.

[0021] Furthermore, as a more preferred embodiment of this utility model, the corner of the connector body inserted into the insertion window is rounded.

[0022] Based on the same inventive concept, this utility model also provides an electric vehicle, including the handlebar folding state locking device as described above. Attached Figure Description

[0037] Example

[0038] This embodiment aims to address the problems in the prior art where the handlebars are not securely locked when folded, are prone to loosening, and produce abnormal noises. (Refer to...) Figure 1-6 As shown, in this embodiment, based on the connection between the foldable handlebar body 21 and the frame body 1, a connecting structure 22 is provided on the handlebar body 21, which cooperates with the locking component 3 integrated in the insertion window 11 of the frame body 1 to form a plug-in mechanical lock. This ensures that the buckle position 2211 and the locking end 31 are firmly engaged after the handlebar 2 is folded, effectively resisting vibration and impact, while reducing noise problems caused by friction or gaps, and significantly improving the stability of the folded state and the user experience.

[0039] Reference Figure 1-2 As shown, a handlebar 2 folding locking device includes a vehicle body 1, a handlebar 2, and a locking component 3.

[0040] Reference Figure 3-4 As shown, a plug-in window 11 is provided on the top of the vehicle body 1; for example, the plug-in window 11 may be a rectangular groove formed on the top surface of the vehicle body 1.

[0041] Reference Figure 5-6 As shown, the handlebar 2 includes a foldable handlebar body 21 and a connecting structure 22 disposed on the handlebar body 21. For example, one end of the connecting structure 22 is adapted to the insertion window 11 and can be inserted accordingly.

[0042] Reference Figure 2-4 As shown, the locking component 3 is located inside the insertion window 11. When the handlebar body 21 is folded, one end of the connecting structure 22 can be inserted into the insertion window 11; the locking end 31 of the locking component 3 can be snapped together with one end of the connecting structure 22.

[0043] Reference Figure 5-6 As shown, in some embodiments, the connecting structure 22 includes a connecting body 221, one end of which is rotatably connected to the handlebar body 21; the other end of the connecting body 221 is provided with a latching position 2211 adapted to the latching end 31 of the locking component 3; when the handlebar body 21 is not fully folded, the other end of the connecting body 221 can rotate around one end of the connecting body 221 under the action of an external force, so that the latching position 2211 can be aligned with the latching end 31 of the locking component 3, and when the handlebar body 21 is fully folded, the latching position 2211 is engaged with the latching end 31 of the locking component 3. For example, the connecting body 221 can be a strip-shaped plate structure, one end of which is rotatably connected to the other end which can be correspondingly inserted into the insertion window 11, and the other end of the strip-shaped plate structure is provided with a through hole, and the latching end 31 of the locking component 3 can be a pin adapted to the through hole.

[0044] Reference Figure 6 As shown, in some embodiments, a magnetic window 2212 is provided at the other end of the connector body 221; the connecting structure 22 also includes a magnetic element disposed at the magnetic window 2212. The magnetic element can be attracted to the surface of the handlebar body 21, and under the action of external force, it can overcome the magnetic attraction and drive the other end of the connector body 221 away from the handlebar body 21. For example, the magnetic window 2212 can be a circular groove opened in the connector body 221, with the magnetic window 2212 facing the handlebar 2. The magnetic element can be a circular magnet adapted to the circular groove, and fixed in the circular groove by pasting or snapping. The position of the handlebar body 21 corresponding to the magnetic element can be made of iron material or another adapted magnetic element can be provided. For example, a threaded hole is provided at the corresponding position, and a bolt a is screwed in, with the bolt head adapted to and attracted to the magnetic element.

[0045] Reference Figure 6 As shown, in some embodiments, the connecting structure 22 further includes a hook portion 2213 disposed on the connector body 221, the hook portion 2213 being used to hook onto an external object. It is understood that the hook portion 2213 is used to hook onto an external object, which refers to an external object with a hanging lug, such as a plastic bag, hanging bag, or hanging pouch. The hook portion 2213 is integrally formed with the connecting body, such as forming a V-shaped opening structure with the connecting body.

[0046] Reference Figure 6As shown, in some embodiments, the hook portion 2213 is disposed in the middle of the connector body 221 on the side facing the vehicle body 1; the other end of the connector body 221 is rotated so that the hook portion 2213 abuts against the vehicle body 1, at which time the latching position 2211 corresponds to the position of the insertion window 11, so that the latching position 2211 can be positioned to insert into the insertion window 11. It can be understood that the hook portion 2213 can also be used for positioning the rotation angle of the connector body 221, so that the user can quickly unfold the connector body 221 and align the connector body 221 with the insertion window 11.

[0047] Reference Figure 5 As shown, in some embodiments, the handlebar body 21 is provided with a receiving window 211; the top of the connector body 221 is provided with a stepped portion 2214, which is adapted to the receiving window 211. The top two sides of the stepped portion 2214 are connected to the two sides of the receiving window 211 through pivots 2215, and the stepped portion 2214 is disposed within the receiving window 211. For example, the connector body forms an asymmetrical Y-shaped structure 22, one side of the Y-shape is shorter than the other side, the shorter side forms a hook portion 2213, and the longer side forms a structure adapted to the receiving window 211, which can be flatly attached to the receiving window 211. The bottom of the Y-shape is flatly attached to the bottom plane outside the receiving window 211.

[0048] Reference Figure 3 As shown, in some embodiments, the locking component 3 includes: a housing 32, a telescopic rod 33, an elastic element 34, and a movable unlocking element 35.

[0049] The housing 32 is provided with a sliding hole 321 and an unlocking window 322. The telescopic rod 33 is disposed inside the housing 32, one end of which is a locking end 31, which can extend out of the housing 32 through the sliding hole 321 and can move along the sliding hole 321. The elastic element 34 is disposed inside the housing 32, one end of which abuts against the other end of the telescopic rod 33, and the other end of which abuts against the inner wall of the housing 32. The movable release element 35 is disposed within the release window 322 and can slide along the release window 322. Guide grooves 351 are respectively provided on both sides of the movable release element 35, and a guide rod 331 is provided in the middle of the telescopic rod 33. The guide rods 331 extend to the guide grooves 351 on both sides of the movable release element 35 and can slide along the guide grooves 351. The guide grooves 351 are inclined. The movable release element 35 can be driven by external force to slide along the release window 322, and the guide rods 331 can slide along the guide grooves 351, causing the locking end 31 to retract, thereby limiting the locking position 2211. For example, the telescopic rod 33 adopts an existing spring structure. The cross-section of the movable unfastener 35 is a U-shaped structure. Guide grooves 351 are provided on both sides of the U-shaped structure. The guide grooves 351 are inclined relative to the telescopic rod. The displacement of the guide grooves 351 can drive the guide rod 331 to slide to one side of the elastic member 34, thereby causing the telescopic rod to compress the elastic member 34 axially.

[0050] Reference Figure 3 As shown, in some embodiments, a guide ramp b is provided on the side of the locking end 31 facing the insertion window 11. When the other end of the connector body 221 is pushed into the insertion window 11 along the guide ramp b, it can drive one end of the telescopic rod 33 to retract until the other end of the connector body 221 can be fully inserted into the insertion window 11. Under the action of the restoring force of the elastic member 34, one end of the telescopic rod 33 pushes one end of the telescopic rod 33 into the buckle position 2211 to achieve the locking state.

[0051] Reference Figure 6 As shown, in some embodiments, the corner of one end of the connector body 221 inserted into the insertion window 11 is rounded.

[0052] This embodiment also provides an electric vehicle, including the aforementioned handlebar 2 folding state locking device.
