[0002] Bicycles, also known as bicycles or bikes, are usually small two-wheeled land vehicles. After riding on the bicycle, people use pedaling as power. It is a green and environmentally friendly means of transportation. In today's society, people are increasingly concerned about environmentally friendly transportation, and more and more people use bicycles as fitness equipment for cycling and exercise. At present, the handlebar position of most bicycles on the market is fixed and cannot be flexibly adjusted according to the rider's height, arm length, riding habits or riding scenes. This design limits the rider's comfort and controllability to a certain extent, thus affecting the overall riding experience. At the same time, if the handlebar position is too low or too high or the distance between the handlebars is too close or too far, the rider may feel fatigue and discomfort in the arms, shoulders and even waist after riding for a long time, because this may cause the rider to maintain an unnatural and uncomfortable body posture. Especially for some users with special body shapes or special needs (such as children, tall people, disabled people, etc.), the setting of fixed handlebars undoubtedly increases their riding difficulty and discomfort.

[0044] In order to make the utility model's purpose, features, and advantages more obvious and easy to understand, the following will be combined with the drawings in the utility model embodiments to clearly and completely describe the technical solutions in the utility model embodiments. Obviously, the embodiments described below are only part of the utility model embodiments, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0045] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0046] Unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0047] See also Figure 1-Figure 4 The present application provides an embodiment of a bicycle with an adjustable handle, comprising: a handle frame, two handles (a left handle 11 and a right handle 12) located on the left and right sides of the handle frame, a telescopic mechanism 4 and a lifting mechanism 5; the handle frame comprises a front fork, a front fork top 31 located above the front fork and a front fork crossbeam 35; the telescopic mechanism 4 is arranged in the front fork crossbeam 35; the telescopic mechanism 4 comprises a first stepping motor 41, a first screw rod 42 and a first threaded cap 43;

[0048] A first stepper motor 41 is disposed on both sides of the front fork top 31; the output shaft of each first stepper motor 41 is drivingly connected to a first screw rod 42, the first screw rod 42 is threadedly connected to a first threaded cap 43, and the first threaded cap 43 is fixedly connected to the handle;

[0049] The lifting mechanism 5 includes a second stepper motor 51, a second screw rod 52 and a second threaded cap 53; the second stepper motor 51 is arranged at the top of the front fork; the output shaft of the second stepper motor 51 is drivingly connected to the second screw rod 52, the second screw rod 52 is threadedly connected to the second threaded cap 53, and the second threaded cap 53 is fixedly connected to the top 31 of the front fork.

[0050] It can be understood that when the first stepper motor 41 rotates forward or reversely, the first stepper motor 41 drives the first screw 42 to rotate, and the first screw 42 and the first threaded cap 43 move relative to each other, so that the first threaded cap 43 moves in the direction of the first screw 42, thereby increasing or reducing the distance between the two handles; similarly, when the second stepper motor 51 rotates forward or reversely, the second stepper motor 51 drives the second screw 52 to rotate, and the second screw 52 and the second threaded cap 53 move relative to each other, so that the second threaded cap 53 moves in the direction of the second screw 52, ​​thereby increasing or reducing the height of the two handles.

[0051] The telescopic mechanism 4 and the lifting mechanism 5 are provided to flexibly adjust the handlebar position of the bicycle, such as the distance or height between the two handlebars, and to improve the adjustability of the handlebar, so as to improve the flexibility and applicability of the bicycle, thereby improving the comfort and controllability of the rider; during the riding process, the rider can adjust the position of the handlebar according to his or her body shape, different road conditions, speed and physical fatigue to achieve the best riding state, reduce riding fatigue and improve the riding experience.

[0052] In a specific embodiment, see Figure 5 and Figure 6 A nut assembly 6 is provided on each threaded cap; a guide plate 7 is installed on the side of each stepping motor, and the guide plate 7 is provided with a sliding channel 71 that allows the nut assembly 6 to slide and pass through.

[0053] It should be noted that the nut assembly 6 includes two nuts 61 and two screws 62. The upper surface of the threaded cap has two through holes vertically opened, and the two screws 62 are respectively inserted into the two through holes; the bottom end of the screw 62 passes through the through hole and the sliding channel 71 and is threadedly connected to the nut 61.

[0054] During assembly, the nut 61 is rotated to adjust the tightness of the nut 61 and the screw 62, and while ensuring the tightness of the nut and the screw 62, the screw 62 can also slide smoothly in the sliding channel 71. In this way, when the screw rod and the threaded cap move relative to each other, the nut 61, the screw 62 and the guide plate 7 are combined to ensure that the threaded cap can move along the direction of the guide plate 7 and ensure the stability of the movement of the threaded cap. For the telescopic mechanism 4, the threaded cap can move forward or backward in the axial direction; for the lifting mechanism 5, the threaded cap can move forward or backward in the longitudinal direction.

[0055] In a specific embodiment, the first connecting rod 44 and the second connecting rod 54; the first threaded cap 43 is connected to the handle through the first connecting rod 44; the second threaded cap 53 is connected to the front fork top 31 through the second connecting rod 54.

[0056] In a specific embodiment, it further includes: a limiting member 72 ; a limiting member 72 is disposed at one end of the first screw rod 42 and the second screw rod 52 .

[0057] It should be noted that when the first stepper motor 41 rotates forward to drive the first threaded cap 43 to move axially, thereby increasing the distance between the handles, or when the second stepper motor 51 rotates forward to drive the second threaded cap 53 to move longitudinally, thereby increasing the height of the handles, the limit member 72 is used to limit the moving distance of the first threaded cap 43 or the second threaded cap 53; in addition, in order to further improve the stability of the screw, the limit member 72 is fixedly connected to the guide plate 7.

[0058] See also Figure 7-Figure 11 In a specific embodiment, it also includes: a pressure sensor 13 and a warning light 33; the pressure sensor 13 is arranged on the handle; the warning light 33 is arranged on the handle frame.

[0059] It should be noted that, in order to ensure the riding safety of the rider during riding, a warning light 33 and a pressure sensor 13 are provided to ensure that the rider holds the handlebar 1 tightly during riding; specifically, the pressure sensor 13 is used to collect pressure data acting on the handlebar 1. Specifically, when the rider is riding, if the rider holds the handlebar 1 with one hand for a long time or leaves the handlebar 1 with both hands, the warning light 33 flashes at this time, alerting the rider to pay attention to riding safety, and reminding the rider to adopt a correct grip posture to ensure riding safety, thereby effectively reducing the probability of accidents.

[0060] In a specific embodiment, a button assembly 34 is provided on the grip frame 3, and the button assembly 34 is electrically connected to the first stepper motor 41 and the second stepper motor 51 respectively; the button assembly 34 is used to control the operating status of the first stepper motor 41 and the second stepper motor 51.

[0061] It should be noted that the button assembly 34 includes a first button and a second button, the first button is used to control the operating state of the first stepper motor 41, and the second button is used to control the operating state of the first stepper motor 41; the button assembly 34 is provided to facilitate the rider to control the position of the handlebar, and the rider can adjust the position of the handlebar at any time according to his or her own riding status or road conditions, thereby reducing the riding difficulty of the rider.

[0062] Taking the first button as an example, in actual use, a long press can be set to start or shut down the operation state of the first stepper motor 41. When the first stepper motor 41 is started, a short press of the first button can be represented as the first stepper motor 41 rotating forward, thereby increasing the distance between the handles; short presses of the first button twice can be represented as the first stepper motor 41 rotating reversely, thereby shortening the distance between the handles.

[0063] In a specific embodiment, the bicycle body bracket is also included; an infrared sensor 21 is installed near the pedal of the bicycle body bracket; the infrared sensor 21 is used to collect the user's riding frequency (such as the number of pedaling circles per minute). The rider can record the exercise status according to the riding frequency collected by the infrared sensor 21, such as adjusting the pedaling rhythm in time for the riding user to ensure efficient riding under different road conditions and physical conditions.

[0064] In a specific embodiment, it also includes a vibration device 14, a Bluetooth module 22 and a controller 2; the controller 2 is electrically connected to the pressure sensor 13, the infrared sensor 21, the warning light 33, the vibration device 14, the Bluetooth module 22, the first stepper motor 41 and the second stepper motor 51 respectively; the Bluetooth module 22 and the controller 2 are embedded in the interior of the front fork top 31, and are used to monitor and collect data collected by the pressure sensor 13, the infrared sensor 21, the button assembly 34 and the Bluetooth module 22, and are used to control the warning light 33, the vibration device 14, the first stepper motor 41 and the second stepper motor 51.

[0065] It is understandable that those skilled in the art can, based on common knowledge, perform calculations and analyses on the collected pressure data, cycling cadence and cycling navigation data, and the controller 2 can perform calculations on the above-mentioned real-time collected data to enhance the flexibility and applicability of the product and improve the rider's riding experience.

[0066] For example, during a user's riding, if the controller 2 does not receive the handlebar pressure data within a preset time or detects that the pressure data is lower than a preset pressure value, the controller 2 can send an alarm signal to the warning light 33 to control the warning light 33 to flash red, alerting the rider to pay attention to riding safety.

[0067] Among them, the vibration device 14 can be installed in the handlebar; the Bluetooth module 22 is connected to the external communication device for communication, and is used to transmit the rider's riding navigation information uploaded by the external communication device to the controller 2. The controller 2 can generate a corresponding vibration signal according to the riding direction in the riding navigation data and transmit it to the vibration device 14. Exemplarily, during normal riding (the rider's hands hold the left handlebar 11 and the right handlebar 12 respectively, when the next intersection is a fork in the road, and the rider needs to turn right at the next intersection, the riding navigation data is transmitted to the controller 2 through the Bluetooth module 22. The controller 2 controls the vibration device 14 of the right handlebar 12 to send a vibration signal according to the riding direction data (to the right) in the riding navigation data, so as to remind the rider that he needs to turn right at the next intersection, thereby improving the riding efficiency and safety of the user.

[0068] At the same time, those skilled in the art can also use the controller 2 to control the start of the corresponding stepper motor according to the collected cycling navigation data and cycling cadence; for example, in order to achieve scientific cycling, when the cycling road conditions in the cycling navigation data show that the road conditions ahead are complex and crowded, and the rider's cycling cadence is higher than the normal cadence, the normal cadence can be set to 90r / min according to the fast riding condition, and the controller 2 controls the driving stepper motor to adjust the position of the handlebar to the upper handle position, thereby adjusting the rider's riding posture; otherwise, the position of the handlebar is adjusted to the lower handle position; it can be understood that a third button can also be set on the handlebar frame, and the third button is electrically connected to the controller 2. Before the controller 2 controls the driving stepper motor, the warning light 33 can flash green to remind the rider whether to switch the riding posture. If not, the rider can trigger the third button, and the controller 2 does not start the stepper motor.

[0069] Therefore, the controller 2 provides the hardware foundation for the intelligent processing of the bicycle. The specific data analysis and processing involved to further realize the intelligent functions are methods that can be implemented by skilled technicians based on common knowledge. These methods are not within the protection scope of this solution. The above description is only combined with common knowledge to illustrate the beneficial effects that can be achieved by improving this hardware structure. At the same time, the control of the warning light 33, the vibration device 14 and the stepper motor by the controller 2 is also common knowledge. Those skilled in the art can select the controller 2, the warning light 33, the vibration device 14 and the stepper motor for connection as needed. Therefore, how to control is not described in detail in this embodiment; in addition, the pressure sensor 13, the warning light 33, the Bluetooth module 22, the stepper motor, the controller 2, and the button assembly 34 are all prior art, and their working principles and circuit connections are not described in detail.

[0070] In a specific embodiment, it also includes a display screen and a battery module 9; the display screen is installed on the front fork top 31 to display the user's riding data; the battery module 9 is used to provide power to various electrical components of the bicycle. It is understandable that the riding data displayed on the display screen may include but is not limited to riding navigation data and riding cadence.

[0071] In a specific embodiment, the handle frame 3 and the handle 1 are both made of carbon fiber material; the vehicle body support is made of metal material.

[0072] It should be noted that the handle frame 3 made of carbon fiber has the characteristics of light weight, high rigidity and shock absorption, making the bicycle more durable; the body bracket made of metal material can improve the durability and load-bearing capacity of the bicycle and reduce the cost of maintenance.

[0073] As described above, the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments can still be modified, or some of the technical features can be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
