Description

Technical Field

[0001] The present invention relates to the technical field of riding vehicles, and particularly to an adjustable connecting device and a riding vehicle. Background Art

[0002] With the development of society and the improvement of living standards, riding vehicles have become an indispensable means of transportation for people. At present, various merchants have been researching around the performance, quality, lifespan and other characteristics of two-wheeled vehicles, but the impact of vehicle structure on riding has been lacking research. The vehicle structure has an important impact on the riding posture and feeling of users. The handlebar body of the existing riding vehicle is connected to the front fork, and the handlebar cannot be adjusted. When users of different body types ride, their riding experiences are different. For example, when the road surface is bumpy, the speed is fast or slow, the driver leans backward, and the lumbar spine is bent, it will have different impacts on users of different body types. For example, when a relatively short user rides, the existing riding vehicle will make the user unable to fully reach the handlebar, and the user needs to lean forward during riding, resulting in a poor riding experience. When a relatively tall user rides, they cannot fully stretch their arms, which is likely to cause fatigue. Summary of the Invention

[0003] An object of the present invention is to provide an adjustable connecting device and a riding vehicle, which can improve the use experience of the riding vehicle by adjusting the installation position of the support handle on the frame.

[0004] To achieve this purpose, the present invention adopts the following technical solutions:

[0005] In the first aspect, an adjustable connecting device is provided for connecting and installing the support handle and the frame of a riding vehicle. The connecting device includes:

[0006] A connecting piece that can be installed on the frame. The connecting piece is provided with a first mounting hole along its own axis direction. The mounting end of the support handle is adjustably installed in the first mounting hole. The connecting piece has a clamping state for clamping the mounting end and a releasing state for releasing the mounting end;

[0007] A locking shaft is vertically and penetratingly installed in the connecting piece. One end of the locking shaft abuts against and defines the outer wall of the connecting piece. An adjusting block is rotatably installed at the other end of the locking shaft. The curved surface of the adjusting block abuts against the outer wall of the connecting piece. Rotating the adjusting block can drive the connecting piece to switch between the clamping state and the releasing state.

[0008] As an optional technical solution, the adjusting block is a cam. When the connecting piece is in the clamping state, the horizontal height of the center of the cam surface of the adjusting block is lower than the horizontal height of the rotation center of the adjusting block;

[0009] When the connecting member is in the released state, the horizontal height of the center of the cam surface of the adjusting block is greater than or equal to the horizontal height of the rotation center of the adjusting block.

[0010] As an alternative technical solution, a cutting groove is axially formed on the side wall of the connecting member.

[0011] As an alternative technical solution, the connecting device further includes a rotation center member. The support handle can rotate around the rotation center member. The rotation center member is vertically and penetratingly installed in the connecting member and is located below the locking shaft. A long hole groove is radially formed through the installation end. The section of the locking shaft penetrating the connecting member and the section of the rotation center member penetrating the connecting member both penetrate the installation end through the long hole groove.

[0012] When the support handle is adjusted to the highest position, the rotation center member abuts against the inner wall surface of the lower end of the long hole groove.

[0013] When the support handle is adjusted to the lowest position, the locking shaft abuts against the inner wall surface of the upper end of the long hole groove.

[0014] As an alternative technical solution, an adjustment hole and a second installation hole are formed on the side wall of the connecting member. The locking shaft is adjustably installed in the adjustment hole, and the rotation center member is fixedly installed in the second installation hole.

[0015] When the support handle is adjusted to the most forward position, the locking shaft abuts against the inner wall surface of the front end of the adjustment hole.

[0016] When the support handle is adjusted to the most rearward position, the locking shaft abuts against the inner wall surface of the rear end of the adjustment hole.

[0017] As an alternative technical solution, the connecting device further includes a safety component. The safety component is installed on the adjusting block. The safety component includes a limiting block. A limiting groove is formed at one end of the locking shaft where the adjusting block is installed. One end of the limiting block can slide into the limiting groove to limit the rotation of the adjusting block relative to the locking shaft.

[0018] As an alternative technical solution, the safety component further includes a connecting rod. One end of the connecting rod is connected to the adjusting block. The connecting rod is used to drive the adjusting block to rotate. A first through hole is formed inside the connecting rod. A cable is slidably installed in the first through hole. One end of the cable is connected to the limiting block. The cable is used to drive the limiting block to slide into or out of the limiting groove.

[0019] As an alternative technical solution, a sheath is threadedly connected to one end of the connecting rod away from the adjusting block. A thrust structure is installed inside the sheath, and the other end of the cable is connected to the thrust structure.

[0020] As an alternative technical solution, the thrust structure includes a limiting block and a spring. One end of the limiting block is connected to the cable, and the other end of the limiting block is connected to the spring. The spring presses the limiting block against the inner wall of the sheath.

[0021] In a second aspect, a riding vehicle is provided, including a frame and a support handle. The frame and the support handle are connected and installed through any of the connecting devices described above.

[0022] The beneficial effects of the present invention are as follows:

[0023] In the adjustable connecting device provided by the present invention, the adjusting block is rotatably installed at one end of the locking shaft. The curved surface of the adjusting block abuts against the outer wall of the connecting member. When it is necessary to adjust the position of the support handle relative to the frame, the adjusting block is rotated, and the connecting member switches to the loosening state. The user manually adjusts the support handle. When the support handle is adjusted to a position suitable for the user's operation, the adjusting block is rotated in the reverse direction, and the connecting member switches to the clamping state. The support handle is clamped and fixed by the connecting member, thereby preventing the support handle from loosening relative to the frame. BRIEF DESCRIPTION OF THE DRAWINGS

[0047] As Figures 1 to 8 shown, this embodiment provides a riding vehicle, including a frame 100 and a support handle 200. The frame 100 and the support handle 200 are connected and installed through a connecting device. The connecting device is used to adjust the installation position of the support handle 200 on the frame 100 to meet the riding experience of users. In this embodiment, the support handle 200 is a handlebar. In some other embodiments, the support handle 200 can also be a seat handle.

[0048] As Figures 1 to 3 shown, the connecting device of this embodiment includes a connecting member 1 and a locking shaft 2. The connecting member 1 can be installed on the frame 100. The connecting member 1 is provided with a first installation hole 11 along its own axis direction. The installation end 201 of the support handle 200 can be adjustably installed in the first installation hole 11. The connecting member 1 has a clamping state for clamping the installation end 201 and a releasing state for releasing the installation end 201. The locking shaft 2 is vertically penetrated and installed in the connecting member 1. One end of the locking shaft 2 abuts against and limits the outer wall of the connecting member 1. An adjusting block 3 is rotatably installed at the other end of the locking shaft 2. The curved surface of the adjusting block 3 abuts against the outer wall of the connecting member 1. Rotating the adjusting block 3 can drive the connecting member 1 to switch between the clamping state and the releasing state.

[0049] Specifically, the adjusting block 3 is rotatably installed at one end of the locking shaft 2, and the curved surface of the adjusting block 3 abuts against the outer wall of the connecting member 1. When it is necessary to adjust the position of the support handle 200 relative to the frame 100, rotate the adjusting block 3 so that the base circle surface of the adjusting block 3 abuts against the outer wall of the connecting member 1, and the connecting member 1 switches to the releasing state. The user manually adjusts the support handle 200. When the support handle 200 is adjusted to a position suitable for the user to operate, rotate the adjusting block 3 in the reverse direction so that the cam curved surface of the adjusting block 3 abuts against the outer wall of the connecting member 1, and the connecting member 1 switches to the clamping state. The support handle 200 is clamped and fixed by the connecting member 1, thereby preventing the support handle 200 from loosening relative to the frame 100.

[0050] Optionally, a cutting groove is axially provided on the side wall of the connecting member 1 to make the connecting member 1 more easily elastically deformed.

[0051] Optionally, the adjusting block 3 is a cam. When the connecting member 1 is in the clamping state, the horizontal height of the center of the cam curved surface of the adjusting block 3 is lower than the horizontal height of the rotation center of the adjusting block 3; when the connecting member 1 is in the releasing state, the horizontal height of the center of the cam curved surface of the adjusting block 3 is greater than or equal to the horizontal height of the rotation center of the adjusting block 3. The rotation center of the adjusting block 3 is the center of the base circle. When the connecting member 1 is in the clamping state, setting the horizontal height of the center of the cam curved surface of the adjusting block 3 to be lower than the horizontal height of the rotation center of the adjusting block 3 can ensure that the adjusting block 3 realizes self-locking by relying on the reverse acting force of the connecting member 1, and the adjusting block 3 will not automatically rotate during the riding process.

[0052] In this embodiment, the connecting device further includes a rotation center member 4. The support handle 200 can rotate around the rotation center member 4. The rotation center member 4 vertically penetrates and is installed in the connecting member 1 and is located below the locking shaft 2. A long hole slot 202 is radially penetrated through the installation end 201. A section of the locking shaft 2 penetrating through the connecting member 1 and a section of the rotation center member 4 penetrating through the connecting member 1 both penetrate through the installation end 201 via the long hole slot 202.

[0053] As Figure 4 and Figure 5 shown, when the support handle 200 is adjusted to the highest position, the rotation center member 4 abuts against the inner wall surface of the lower end of the long hole slot 202; when the support handle 200 is adjusted to the lowest position, the locking shaft 2 abuts against the inner wall surface of the upper end of the long hole slot 202.

[0054] The rotation center member 4 and the locking shaft 2 can limit the adjustment of the support handle 200 between the highest position and the lowest position, preventing the support handle 200 from completely detaching from the vehicle frame 100. Optionally, the rotation center member 4 is a bolt.

[0055] As Figure 6 and Figure 7 shown, in this embodiment, an adjustment hole 12 and a second installation hole 13 are provided on the side wall of the connecting member 1. The locking shaft 2 is adjustably installed in the adjustment hole 12, and the rotation center member 4 is fixedly installed in the second installation hole 13. The support handle 200 rotates with the rotation center member 4 as the rotation center line.

[0056] When the support handle 200 is adjusted to the most forward position, the locking shaft 2 abuts against the inner wall surface of the front end of the adjustment hole 12; when the support handle 200 is adjusted to the most rearward position, the locking shaft 2 abuts against the inner wall surface of the rear end of the adjustment hole 12.

[0057] When it is necessary to adjust the support handle 200 away from the user, the connecting member 1 is switched to the loose state, the support handle 200 is pushed forward (i.e., the support handle 200 is moved away from the user), the locking shaft 2 abuts against the inner wall surface of the front end of the adjustment hole 12, and then the connecting member 1 is switched to the clamping state; when it is necessary to adjust the support handle 200 closer to the user, the connecting member 1 is switched to the loose state, the support handle 200 is pushed backward (i.e., the support handle 200 is moved closer to the user), the locking shaft 2 abuts against the inner wall surface of the rear end of the adjustment hole 12, and then the connecting member 1 is switched to the clamping state.

[0058] As Figure 8As shown, in this embodiment, the connection device also includes a safety component 5, which is installed on the adjustment block 3. The safety component 5 includes a limit block 51. The end of the locking shaft 2 where the adjustment block 3 is installed is provided with a limit slot 21, and one end of the limit block 51 can slide into the limit slot 21 to limit the rotation of the adjustment block 3 relative to the locking shaft 2. When the connecting member 1 is switched to the clamping state, in order to prevent the adjustment block 3 from rotating due to external force, causing the connecting member 1 to switch to the loose state by mistake, the safety component 5 is installed on the adjustment block 3 in this embodiment. The limit block 51 of the safety component 5 is limited between the adjustment block 3 and the locking shaft 2, and the adjustment block 3 cannot rotate relative to the locking shaft 2, thereby preventing the connecting member 1 from switching from the clamping state to the loose state during riding, which may cause a safety accident.

[0059] In this embodiment, the safety assembly 5 further includes a connecting rod 52, one end of which is connected to the adjusting block 3. The connecting rod 52 is used to drive the adjusting block 3 to rotate. The user can directly turn the connecting rod 52 to rotate the adjusting block 3.

[0060] In this embodiment, a first through hole is provided inside the connecting rod 52, and a cable 53 is slidably installed in the first through hole, one end of the cable 53 is connected to the limit block 51, and the cable 53 is used to drive the limit block 51 to slide into or out of the limit groove 21. Optionally, the cable 53 is a steel wire rope, and the user can drive the limit block 51 through the steel wire rope. When the limit block 51 is out of the limit groove 21, the connecting rod 52 is moved to rotate the adjustment block 3.

[0061] In this embodiment, the end of the connecting rod 52 away from the adjusting block 3 is threadedly connected with a sheath 54, a push-pull structure is installed in the sheath 54, and the other end of the cable 53 is connected to the push-pull structure. Optionally, one end of the connecting rod 52 is provided with an external thread, and one end of the sheath 54 is provided with an internal thread, and the connecting rod 52 and the sheath 54 are threadedly connected. When the user rotates the sheath 54 in the direction of starting the safety, the end of the connecting rod 52 with the external thread extends into the sheath 54, and the cable 53 slidably installed in the connecting rod 52 pushes the limit block 51 to the limit groove 21; when the user rotates the sheath 54 in the direction of unlocking the safety, the end of the connecting rod 52 with the external thread moves out of the sheath 54, and the cable 53 pulls the limit block 51 to slide out of the limit groove 21.

[0062] In this embodiment, the push structure includes a limiting block 55 and a spring 56. One end of the limiting block 55 is connected to the cable 53, and the other end of the limiting block 55 is connected to the spring 56. The spring 56 pushes the limiting block 55 to contact the inner wall of the sheath 54. When the sheath 54 rotates relative to the connecting rod 52, the spring 56 always pushes the limiting block 55 to the inner wall of the sheath 54. The position of the limiting block 55 relative to the sheath 54 remains unchanged, so that the cable 53 can slide relative to the connecting rod 52.

[0063] In addition, the above are only the preferred embodiments of the present invention and the technical principles applied. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, re-adjustments and substitutions can be made by those skilled in the art without departing from the protection scope of the present invention. Therefore, although the present invention has been described in more detail through the above embodiments, the present invention is not limited to the above embodiments only. Without departing from the concept of the present invention, more other equivalent embodiments can be included, and the scope of the present invention is determined by the scope of the appended claims.
