Abstract
Description
Technical Field
[0001] The present application relates to the technical field of bicycles, and in particular to a handlebar assembly and a bicycle. Background Art
[0002] As a means of transportation, bicycles play an important role in people's daily lives. Among them, the handlebar is an indispensable component for controlling the forward direction of the bicycle. A wheel is installed on the front fork of a traditional bicycle, the front fork is fixed to the riser, and the handlebar is fixed to the riser to control the swing direction of the front fork wheel.
[0003] However, when a traditional bicycle is parked, the handlebars will take up more space due to their larger left and right dimensions, that is, the handlebars are larger in the width direction of the bicycle. If a large number of bicycles are parked in a designated parking area, the handlebars will easily interfere with and scratch other nearby vehicles due to their protruding ends, thus limiting the upper limit of the number of bicycles that can be parked in the designated parking area, making it more difficult to park and retrieve vehicles, and reducing the user experience of bicycles.
[0004] BACKGROUND OF THE PRESENT APPLICATION The above information disclosed is only for understanding the background of the concept of the present application and may contain information that does not constitute the prior art. Utility Model Content
[0005] Based on this, in order to solve the above problems, it is necessary to provide a handlebar assembly and a bicycle.
[0006] A handlebar assembly, comprising:
[0007] A vertical pipe, wherein a limiting hole is provided on the side surface of the vertical pipe;
[0008] A handlebar, the handlebar comprising a grip and a support tube fixed to the grip, wherein either the support tube or the stand tube is rotatably sleeved on the other, and a positioning hole is formed on a side circumference of the support tube; and
[0009] A limiting structure, wherein the limiting structure includes a limiting member movably connected to the handlebar, wherein the limiting member can move relative to the handlebar to an unlocking position and a locking position, wherein at least a portion of the limiting member is simultaneously inserted into the positioning hole and the limiting hole to lock the handlebar and the seat tube, and wherein at the unlocking position, the limiting member is disengaged from the limiting hole and the positioning hole, and the handlebar can rotate relative to the seat tube.
[0010] The handlebar assembly has at least the following beneficial effects: the stem can be fixed to the front fork of the bicycle to control the direction of travel of the wheel on the front fork. When riding a bicycle equipped with the handlebar assembly, the handlebar can rotate relative to the stem in the unlocked position. At this time, the handlebar can be rotated as a whole to a state substantially perpendicular to the front fork wheel, that is, the handlebar is substantially perpendicular to the frame. Then, the limit structure is moved to the locking position to fix the handlebar and the stem relatively. At this time, the handlebar can drive the stem to rotate together. It can be understood that this is more in line with the user's riding habits. The user faces the handlebar head-on and can put both hands on the handlebar in front of the body more naturally. If a bicycle equipped with the handlebar assembly is to be parked in a specified parking area, and there are a large number of bicycles in the specified area and the distance between them is narrow, the bicycle using the handlebar assembly of the present application has an advantage. The limiter can be moved to the unlocked position. At this time, the handlebar can be rotated relative to the seat tube, and the handlebar can be rotated to a position roughly parallel to the frame, that is, the handlebar is close to the body of the bicycle, and the front wheel does not need to be rotated. The front wheel can also maintain a position roughly parallel to the frame, which reduces the size of the handlebar in the width direction of the body, and also reduces the size of the handlebar in the width direction of the body occupied by the skewed wheel, which is convenient for parking and taking out the bicycle in a limited space, and reduces interference and scratches with other nearby vehicles, thereby minimizing the risk of damage to the bicycle.
[0011] In one embodiment, the limiting hole includes a first limiting hole and a second limiting hole, and the first limiting hole and the second limiting hole are arranged at intervals along the circumference of the seat tube; the locking position includes a first locking position and a second locking position, in the first locking position, the positioning hole is aligned with the first limiting hole, and the limiting member is inserted into the positioning hole and the first limiting hole, and in the second locking position, the positioning hole is aligned with the second limiting hole, and the limiting member is inserted into the positioning hole and the second limiting hole. For example, when riding a bicycle equipped with the handlebar assembly, in the unlocking position, the handlebar can rotate relative to the seat tube, and the handlebar can be rotated as a whole to a state substantially perpendicular to the front fork wheel, that is, the handlebar is substantially perpendicular to the frame, and then the limiting structure is moved to the first locking position, and the handlebar and the seat tube are relatively fixed, and the handlebar can drive the seat tube to rotate together. It can be understood that this is more in line with the user's riding habits, and the user faces the handlebar head-on, and both hands can be placed on the handlebar in front of the body more naturally. For another example, if a bicycle equipped with the handlebar assembly is to be parked in a specified parking area, and there are a large number of bicycles in the specified area and the distance between them is narrow, the bicycle using the handlebar assembly of the present application has an advantage. The limit member can be moved to the unlocked position. At this time, the handlebar can be rotated relative to the seat tube, and the handlebar can be rotated to a position where it is roughly parallel to the frame, that is, the handlebar is close to the body of the vehicle, and the front wheel does not need to be rotated. The front wheel can also maintain a position roughly parallel to the frame, reducing the size of the handlebar in the width direction of the body, and also reducing the size of the wheel skewed and occupied in the width direction of the body, making it convenient to park and take the bicycle in a limited space, and reducing interference and scratches with other nearby vehicles, which can minimize the risk of damage to the bicycle. In order to prevent the handlebar from swaying during parking, the limit structure can be moved to the second locking position, and the limit member can be inserted into the positioning hole and the second limit hole at the same time, so that the handlebar is kept fixed while being close to the body of the vehicle.
[0012] In one embodiment, an axial extension line of the first limiting hole and an axial extension line of the second limiting hole are arranged at an angle.
[0013] In one embodiment, the axial extension line of the first limiting hole and the axial extension line of the second limiting hole are set at a 90-degree angle. It can be understood that in a more preferred embodiment, when riding, the handlebar in the first locking position is roughly perpendicular to the front wheel, and when parked, the handlebar in the second locking position is naturally preferably roughly parallel to the body and the front wheel. In other words, the handlebar in the first locking position is roughly perpendicular to the handlebar in the second locking position. In order to achieve this effect, the axial extension line of the first limiting hole and the axial extension line of the second limiting hole are set at a 90-degree angle in this embodiment.
[0014] In one embodiment, the outer peripheral surface of the vertical tube is further provided with a guide protrusion, and the side peripheral surface of the support tube is provided with a guide slot, and the guide slot can be slidably sleeved on the guide protrusion, and the guide protrusion abuts against the slot wall of the guide slot to limit the axial movement of the support tube in the vertical tube and limit the rotation angle of the support tube in the circumferential direction of the vertical tube. The guide protrusion is inserted into the guide slot, and the guide protrusion abuts against the slot wall of the guide slot in the axial direction of the vertical tube, which can limit the axial movement of the handlebar and the vertical tube, and prevent the handlebar from separating from the vertical tube. In addition, since the length of the guide slot is limited in the extension direction, the travel of the guide protrusion in the guide slot is limited, so the travel of the handlebar relative to the vertical tube is also limited.
[0015] In one embodiment, the guide slot is extended along the circumference of the stand tube, and the guide slot has a first end and a second end in the circumference of the stand tube. When the slot wall of the first end of the guide slot abuts the guide protrusion, the positioning hole is aligned with the first limiting hole, and when the slot wall of the second end of the guide slot abuts the guide protrusion, the positioning hole is aligned with the second limiting hole. The advantage of such a structural setting is that, specifically, when the handlebar is rotated to a state substantially perpendicular to the front wheel, the guide protrusion can be arranged to abut the slot wall of the first end of the guide slot, and the positioning hole is aligned with the first limiting hole. At this time, the limiting structure is inserted into the positioning hole and the first limiting hole, and the handlebar is fixed to the stand tube, that is, quickly positioned to the first locking position. Similarly, when the handlebar is rotated to a state substantially parallel to the front wheel, the guide protrusion can be arranged to abut the slot wall of the second end of the guide slot, and the positioning hole is aligned with the second limiting hole. At this time, the limiting structure is inserted into the positioning hole and the second limiting hole, and the handlebar is fixed to the stand tube, that is, quickly positioned to the second locking position. In other words, the groove wall at the first end of the guide groove and the groove wall at the second end of the guide groove can be used to abut the guide protrusion, so as to have a positioning effect on the relative rotation of the handlebar and the seat tube, so that the user can more conveniently rotate the handlebar relative to the seat tube to the first locking position and the second locking position.
[0016] In one embodiment, the guide protrusion is a screw, and the guide protrusion is threadedly connected to the side surface of the stand pipe.
[0017] In one of the embodiments, the limiting structure further includes a fixing sleeve sleeved on the outer circumference of the support tube and a handle rotatably connected to the fixing sleeve, and the limiting member is provided on a side of the handle close to the support tube.
[0018] In one of the embodiments, a side surface of the fixing sleeve is further provided with an avoidance hole, the avoidance hole is aligned with the positioning hole, and when in the locking position, the limiting member at least partially penetrates the avoidance hole and the positioning hole to be inserted into the limiting hole.
[0019] In one embodiment, the limiting member is a pin, and the pin passes through the handle and is fixed to the handle.
[0020] In one embodiment, the limiting member is at least partially adapted to the limiting hole, and the limiting hole is adapted to the positioning hole. Such a structural setting allows the limiting member to fit closely with the hole wall of the positioning hole after being inserted into the positioning hole, avoiding the gap between the limiting member and the hole wall of the positioning hole, which makes it easy to shake. It also allows the limiting member to fit closely with the hole wall of the limiting hole when inserted into the limiting hole, avoiding the gap between the limiting member and the hole wall of the limiting hole, which makes it easy to shake.
[0021] In one embodiment, the limiting member is at least partially columnar.
[0022] In one embodiment, the number of the handles is two, and the two handles are located on opposite sides of the support tube.
[0023] In one embodiment, the seat tube is used to connect to a front fork of a bicycle to control the driving direction of a wheel connected to the front fork.
[0024] In one embodiment, the vertical tube is rotatably sleeved on the outer circumference of the support tube, the limiting structure also includes a compression spring and a fixed sleeve sleeved on the outer circumference of the vertical tube, a limiting cavity is provided in the fixed sleeve, the limiting member includes an operating part, a connecting part and a limiting part connected in sequence, the connecting part passes through the limiting cavity, the compression spring is arranged in the limiting cavity and sleeved on the connecting part, one end of the compression spring elastically abuts against the limiting part, and the other end of the compression spring elastically abuts against the inner wall of the limiting cavity, the limiting part can be inserted into the limiting hole and the positioning hole under the elastic force of the compression spring, the operating part is located outside the limiting cavity and is used for user operation to pull the limiting part to overcome the elastic force of the compression spring and withdraw from the limiting hole and the positioning hole.
[0025] In one embodiment, the support tube is rotatably sleeved on the outer circumference of the stand tube, the limiting structure also includes a compression spring and a fixed sleeve sleeved on the outer circumference of the support tube, a limiting cavity is provided in the fixed sleeve, the limiting member includes an operating part, a connecting part and a limiting part connected in sequence, the connecting part passes through the limiting cavity, the compression spring is provided in the limiting cavity and sleeved on the connecting part, one end of the compression spring elastically abuts against the limiting part, the other end of the compression spring elastically abuts against the inner wall of the limiting cavity, the limiting part can be inserted into the limiting hole and the positioning hole under the elastic force of the compression spring, the operating part is located outside the limiting cavity and is used for user operation to pull the limiting part to overcome the elastic force of the compression spring and withdraw from the limiting hole and the positioning hole.
[0026] The present application also provides a bicycle, which includes a frame and a handlebar assembly as described in any one of the above embodiments connected to the frame.
[0027] Since the bicycle includes the handlebar assembly described in any of the above embodiments, the bicycle also includes at least the following beneficial effects: the stem of the handlebar assembly can be fixed to the front fork of the bicycle to control the direction of travel of the wheel on the front fork. When the bicycle is to be ridden, the handlebar can rotate relative to the stem in the unlocked position. At this time, the handlebar can be rotated as a whole to a state substantially perpendicular to the front fork wheel, that is, the handlebar is substantially perpendicular to the frame. Then the limit structure is moved to the locking position to fix the handlebar and the stem relatively. At this time, the handlebar can drive the stem to rotate together. It can be understood that this is more in line with the user's riding habits. The user faces the handlebar head-on and can put both hands on the handlebar in front of the body more naturally. If a bicycle is to be parked in a designated parking area, and there are a large number of bicycles in the designated area with narrow spacing between them, then a bicycle using the handlebar assembly of the present application has an advantage, because the limiter can be moved to the unlocked position, and the handlebar can be rotated relative to the seat tube, so that the handlebar can be rotated to a position roughly parallel to the frame, that is, the handlebar is close to the vehicle body, and the front wheel does not need to be rotated, and the front wheel can also be maintained in a position roughly parallel to the frame, thereby reducing the size of the handlebar in the width direction of the vehicle body, and also reducing the size of the handlebar in the width direction of the vehicle body occupied by the skewed wheel, making it convenient to park and take the bicycle in a limited space, and reducing interference and scratches with other nearby vehicles, thereby minimizing the risk of damage to the bicycle.

[0039] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below.
[0040] See also Figures 1 to 6In some embodiments, the present application provides a handlebar assembly 10, which includes a stem 100, a handlebar 200 and a limiting structure 300. The stem 100 has a limiting hole 110 on its lateral circumference, and the handlebar 200 includes a grip 210 and a support tube 220 fixed to the grip 210, and the support tube 220 has a positioning hole 221 on its lateral circumference. Either the support tube 220 or the stem 100 can be rotatably mounted on the other; for example, in one embodiment, the support tube 220 can be rotatably mounted on the outer circumference of the stem 100; for example, in another embodiment, the stem 100 can be rotatably mounted on the outer circumference of the support tube 220. The limiting structure 300 includes a limiting member 310 movably connected to the handlebar 200, and the limiting member 310 can move to an unlocking position and a locking position relative to the handlebar 200. Figure 1 and Figure 4 As shown, in the locking position, at least a portion of the limiting member 310 is inserted into the positioning hole 221 and the limiting hole 110 at the same time to lock the handlebar 200 and the seat tube 100; Figure 2 As shown, in the unlocked position, the limiting member 310 is disengaged from the limiting hole 110 and the positioning hole 221 , and the handlebar 200 can rotate relative to the seat tube 100 .
[0041] The handlebar assembly 10 has at least the following beneficial effects: the stem 100 can be fixed to the front fork of the bicycle to control the direction of travel of the wheel on the front fork. When riding a bicycle equipped with the handlebar assembly 10, in the unlocked position, the handlebar 200 can be rotated relative to the stem 100, such as Figure 1 As shown, at this time, the handlebar 200 can be rotated as a whole to a state that is approximately perpendicular to the front fork wheel, that is, the handlebar 200 is approximately perpendicular to the frame, and then the limiting structure 300 is moved to the locking position, and the handlebar 200 and the seat tube 100 are relatively fixed. At this time, the handlebar 200 can drive the seat tube 100 to rotate together. It can be understood that this is more in line with the user's riding habits when riding. The user faces the handlebar 200 and both hands can be placed on the handlebar 200 in front of the body more naturally. If a bicycle equipped with the handlebar assembly 10 is to be parked in a specified parking area, and there are a large number of bicycles in the specified area and the spacing between them is narrow, then the bicycle using the handlebar assembly 10 of the present application has an advantage. The limiting member 310 can be moved to the unlocking position. At this time, the handlebar 200 can rotate relative to the seat tube 100, as shown in FIG. Figure 3As shown, the handlebar 200 can be rotated to a position roughly parallel to the frame, that is, the handlebar 200 is close to the body of the vehicle, and the front wheel does not need to be rotated, and the front wheel can also maintain a position roughly parallel to the frame, thereby reducing the size of the handlebar 200 in the width direction of the body, and also reducing the size of the wheel skewed and occupied in the width direction of the body, making it convenient to park and take the bicycle in a limited space, and reducing interference and scratches with other nearby vehicles, thereby minimizing the risk of damage to the bicycle.
[0042] Specifically, Figure 6 As shown, in some embodiments, the limiting hole 110 includes a first limiting hole 111 and a second limiting hole 112, and the first limiting hole 111 and the second limiting hole 112 are arranged at intervals along the circumference of the seat tube 100; the locking position includes a first locking position and a second locking position, when in the first locking position, the positioning hole 221 is aligned with the first limiting hole 111, and the limiting member 310 is inserted into the positioning hole 221 and the first limiting hole 111, and when in the second locking position, the positioning hole 221 is aligned with the second limiting hole 112, and the limiting member 310 is inserted into the positioning hole 221 and the second limiting hole 112. For example, when riding a bicycle equipped with the handlebar assembly 10, in the unlocked position, the handlebar 200 can rotate relative to the seat tube 100, as shown in FIG. Figure 1 As shown, at this time, the handlebar 200 can be rotated as a whole to a state that is approximately perpendicular to the front fork wheel, that is, the handlebar 200 is approximately perpendicular to the frame, and then the limiting structure 300 is moved to the first locking position to relatively fix the handlebar 200 and the seat tube 100. At this time, the handlebar 200 can drive the seat tube 100 to rotate together. It can be understood that this is more in line with the user's riding habits when riding. The user faces the handlebar 200 and both hands can be placed on the handlebar 200 in front of the body more naturally. For another example, if a bicycle equipped with the handlebar assembly 10 is to be parked in a specified parking area, and there are a large number of bicycles in the specified area and the spacing between them is narrow, then the bicycle using the handlebar assembly 10 of the present application has an advantage, and the limiting member 310 can be moved to the unlocking position. At this time, the handlebar 200 can rotate relative to the seat tube 100, as shown in FIG. Figure 3As shown, the handlebar 200 can be rotated to a position roughly parallel to the frame, that is, the handlebar 200 is close to the body of the vehicle, and the front wheel does not need to be rotated, and the front wheel can also maintain a position roughly parallel to the frame, thereby reducing the size of the handlebar 200 in the width direction of the body, and also reducing the size of the wheel skewness and the size occupied in the width direction of the body, so that it is convenient to park and take the bicycle in a limited space, and reduce interference and scratches with other nearby vehicles, which can minimize the risk of damage to the bicycle. In order to prevent the handlebar 200 from swaying during parking, the limiting structure 300 can be moved to the second locking position at this time, and the limiting member 310 can be inserted into the positioning hole 221 and the second limiting hole 112 at the same time, so that the handlebar 200 can be kept fixed while being close to the body of the vehicle.
[0043] More specifically, if Figure 6 As shown, in some embodiments, an axial extension line of the first limiting hole 111 and an axial extension line of the second limiting hole 112 are arranged at an angle.
[0044] For example, in Figure 6 In the illustrated embodiment, the axial extension line of the first limiting hole 111 and the axial extension line of the second limiting hole 112 are arranged at a 90-degree angle. It is understandable that in a more preferred embodiment, when riding, the handlebar 200 in the first locking position is substantially perpendicular to the front wheel, and when parked, the handlebar 200 in the second locking position is naturally preferably substantially parallel to the vehicle body and the front wheel. In other words, the handlebar 200 in the first locking position is substantially perpendicular to the handlebar 200 in the second locking position. In order to achieve this effect, the axial extension line of the first limiting hole 111 and the axial extension line of the second limiting hole 112 are arranged at a 90-degree angle in this embodiment.
[0045] See also Figure 1 , Figure 2 , Figure 5 and Figure 6In some embodiments, the outer circumferential surface of the seat tube 100 is further provided with a guide protrusion 120, and the lateral circumferential surface of the support tube 220 is provided with a guide slot 222, and the guide slot 222 is slidably sleeved on the guide protrusion 120, and the guide protrusion 120 abuts against the slot wall of the guide slot 222 to limit the axial movement of the support tube 220 in the seat tube 100 and the rotation angle of the support tube 220 in the circumferential direction of the seat tube 100. The guide protrusion 120 is inserted into the guide slot 222, and the guide protrusion 120 abuts against the slot wall of the guide slot 222 in the axial direction of the seat tube 100, which can limit the axial movement of the handlebar 200 and the seat tube 100, and prevent the handlebar 200 from being separated from the seat tube 100. In addition, since the length of the guide slot 222 is limited in the extension direction, the sliding stroke of the guide protrusion 120 in the guide slot 222 is limited, so the rotation stroke of the handlebar 200 relative to the seat tube 100 is also limited.
[0046] Furthermore, if Figure 5 As shown, in some embodiments, the guide slot 222 is extended along the circumference of the riser 100, and the guide slot 222 has a first end 2221 and a second end 2222 in the circumference of the riser 100. When the slot wall of the first end 2221 of the guide slot 222 abuts against the guide protrusion 120, the positioning hole 221 is aligned with the first limiting hole 111. When the slot wall of the second end 2222 of the guide slot 222 abuts against the guide protrusion 120, the positioning hole 221 is aligned with the second limiting hole 112. The advantage of such a structural arrangement is that, specifically, when the handlebar 200 is rotated to a state substantially perpendicular to the front wheel, the guide protrusion 120 can be arranged to abut against the groove wall of the first end 2221 of the guide slot 222, and the positioning hole 221 can be aligned with the first limiting hole 111. At this time, the limiting structure 300 is inserted into the positioning hole 221 and the first limiting hole 111, and the handlebar 200 is fixed to the seat tube 100, that is, it is quickly positioned to the first locking position. Similarly, when the handlebar 200 is rotated to a state substantially parallel to the front wheel, the guide protrusion 120 can be arranged to abut against the groove wall of the second end 2222 of the guide slot 222, and the positioning hole 221 can be aligned with the second limiting hole 112. At this time, the limiting structure 300 is inserted into the positioning hole 221 and the second limiting hole 112, and the handlebar 200 is fixed to the seat tube 100, that is, it is quickly positioned to the second locking position. In other words, the groove wall of the first end 2221 of the guide groove 222 and the groove wall of the second end 2222 of the guide groove 222 can be used to abut the guide protrusion 120, so as to have a positioning effect on the relative rotation of the handlebar 200 and the seat tube 100, so that the user can more conveniently rotate the handlebar 200 relative to the seat tube 100 to the first locking position and the second locking position.
[0047] Furthermore, in some embodiments, the guide protrusion 120 is a screw, and the guide protrusion 120 is threadedly connected to the side surface of the stand pipe 100 .
[0048] See also Figure 2 and Figure 4 In some embodiments, the limiting structure 300 also includes a fixing sleeve 320 sleeved on the outer circumference of the support tube 220 and a handle 330 rotatably connected to the fixing sleeve 320 , and the limiting member 310 is provided on the side of the handle 330 close to the support tube 220 .
[0049] Specifically, Figure 2 As shown, in some embodiments, the side surface of the fixing sleeve 320 is further provided with an avoidance hole 321, and the avoidance hole 321 is aligned with the positioning hole 221. When in the locked position, the limiting member 310 at least partially passes through the avoidance hole 321 and the positioning hole 221 to be inserted into the limiting hole 110.
[0050] Specifically, Figure 4 As shown, in some embodiments, the limiting member 310 is a pin, and the pin passes through the handle 330 and is fixed to the handle 330 .
[0051] Specifically, in some embodiments, the limiting member 310 is at least partially adapted to the limiting hole 110, and the limiting hole 110 is adapted to the positioning hole 221. Such a structural setting allows the limiting member 310 to fit closely with the hole wall of the positioning hole 221 after being inserted into the positioning hole 221, avoiding the gap between the limiting member 310 and the hole wall of the positioning hole 221, which makes it easy to shake. It can also allow the limiting member 310 to fit closely with the hole wall of the limiting hole 110 when inserted into the limiting hole 110, avoiding the gap between the limiting member 310 and the hole wall of the limiting hole 110, which makes it easy to shake.
[0052] Specifically, in some of the embodiments, the limiting member 310 is at least partially columnar.

[0057] The present application also provides a bicycle, which includes a frame and a handlebar assembly 10 described in any one of the above embodiments connected to the frame.
[0058] Since the bicycle includes the handlebar assembly 10 described in any of the above embodiments, the bicycle also includes at least the following beneficial effects: the stem 100 of the handlebar assembly 10 can be fixed to the front fork of the bicycle to control the direction of travel of the wheel on the front fork. When the bicycle is to be ridden, the handlebar 200 can rotate relative to the stem 100 in the unlocked position. At this time, the handlebar 200 can be rotated as a whole to a state substantially perpendicular to the front fork wheel, that is, the handlebar 200 is substantially perpendicular to the frame, and then the limiting structure 300 is moved to the locking position to relatively fix the handlebar 200 and the stem 100. At this time, the handlebar 200 can drive the stem 100 to rotate together. It can be understood that this is more in line with the user's riding habits. The user faces the handlebar 200 head-on and can put both hands on the handlebar 200 in front of the body more naturally. If a bicycle is to be parked in a designated parking area, and there are a large number of bicycles in the designated area with a narrow spacing between them, the bicycle using the handlebar assembly 10 of the present application has an advantage, because the limit member 310 can be moved to the unlocked position, and the handlebar 200 can be rotated relative to the seat tube 100, so that the handlebar 200 can be rotated to a position substantially parallel to the frame, that is, the handlebar 200 is close to the vehicle body, and the front wheel does not need to be rotated, and the front wheel can also maintain a position substantially parallel to the frame, thereby reducing the size of the handlebar 200 in the width direction of the vehicle body, and also reducing the size of the handlebar 200 occupied in the width direction of the vehicle body due to the skew of the wheel, making it convenient to park and take out the bicycle in a limited space, and reducing interference and scratches with other nearby vehicles, thereby minimizing the risk of damage to the bicycle.
