DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, 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.

[0021] See also Figure 1-Figure 3 , this embodiment provides the following technical solutions:

[0022] like Figure 1-Figure 2 As shown, an electric bicycle handlebar and its locking mechanism include: an electric bicycle handlebar body 1, two sets of limiting rings 101 are fixedly installed on the outer surface of the electric bicycle handlebar body 1, a connecting seat 2 is rotatably installed on the outer surface of the limiting ring 101, the connecting seat 2 is installed in the frame of the electric bicycle, a sliding groove 104 is opened in the connecting seat 2, a locking mechanism 3 is slidably installed in the sliding groove 104, the locking mechanism 3 can be engaged with the outer surface of the convex tooth 102, and the convex tooth 102 is fixedly installed between the two sets of limiting rings 101.

[0023] The convex teeth 102 in the limiting ring 101 are arranged at 360 degrees on the outer surface of the handlebar body 1 of the electric bicycle.

[0024] Through the design of the handlebar body 1, the convex teeth 102, the connecting seat 2 and the locking mechanism 3 of the electric bicycle, when the vehicle is placed after use, the handlebar body 1 of the electric bicycle of the vehicle will drive the convex teeth 102 on the outer surface to rotate in the connecting seat 2 according to the user's placement position. After the placement is completed, the locking mechanism 3 will be automatically activated after the power is turned off, and the locking mechanism 3 will slide and push in the sliding groove 104 of the connecting seat 2 to engage with the outer surface of the convex teeth 102. Because the convex teeth 102 are 360° surrounded, the user can place the handlebar body 1 of the electric bicycle at any position and can also get the meshing and locking operation, without the need to swing the handlebar position to the dead angle of rotation to lock it as in the prior art. The user can place the handlebar body 1 of the electric bicycle at any angle, and it can be automatically locked when the power is turned off, without swinging the handlebar body 1 of the electric bicycle to a specific angle or position, which greatly simplifies the operation steps and reduces the cumbersome process of locking the vehicle. In addition, because the locking mechanism 3 can automatically lock the front fork at any position, the situation of failure to lock correctly is avoided, the reliability of anti-theft is increased, and it is ensured that the vehicle can be safely locked under any circumstances.

[0025] This automatic locking design is particularly useful in the application scenarios of shared electric bicycles. Users only need to park the bicycle at any location, and the bicycle will automatically lock the handlebars after the power is cut off. There is no need for users to aim at a specific position, which greatly improves the user experience and the efficiency of vehicle management. At the same time, it also avoids the vehicle being improperly locked due to misoperation or negligence, thereby increasing the safety and reliability of shared bicycles.

[0026] like Figure 3 As shown, the locking mechanism 3 includes a push plate 301 slidably mounted in the sliding groove 104 , and a tooth groove 302 is fixedly mounted on one end of the push plate 301 , and the tooth groove 302 can be engaged with the outer surface of the convex tooth 102 .

[0027] A connecting plate 303 is fixedly installed at one end of the pushing plate 301, and a connecting arm 304 is rotatably installed in the connecting plate 303. The other end of the connecting arm 304 is rotatably connected to the piston rod of the micro electric push rod 305. The micro electric push rod 305 is fixedly installed in the traction groove 103, and the traction groove 103 is opened in the connecting seat 2 and is connected to the sliding groove 104.

[0028] Among them, the micro electric push rod 305 is electrically connected to the battery in the electric bicycle frame, and the micro electric push rod 305 is electrically connected to the controller installed in the electric bicycle frame, the signal input end of the controller is electrically connected to the signal output end of the current sensor, the current sensor is electrically connected to the battery, and is used to detect the current between the positive and negative poles of the battery. When the current between the positive and negative poles of the battery is detected to be reduced to a set threshold, the controller intelligently determines that the battery is in a power-off state. When the current sensor detects that the battery is in a power-off state, the controller controls the micro electric push rod 305 to push the push plate 301 so that the tooth groove 302 engages with the convex tooth 102, thereby locking the electric bicycle handle body 1, and having a good anti-theft function.

[0029] The current sensor can be a closed-loop Hall current sensor of model CHB-100P, and the controller model is a single-chip microcomputer of model STC89C51.

[0030] Through the design of the push plate 301, the tooth groove 302, the connecting arm 304 and the micro electric push rod 305, after the vehicle is powered off, the current sensor will detect that the battery current is lower than the set threshold, and it can be judged that the power has been turned off and send a signal to the controller. The controller will control the micro electric push rod 305 to move through the electronic control end, so that the micro electric push rod 305 pushes the other end of the connecting arm 304 through the piston rod to rotate in the connecting plate 303 of the push plate 301 until the connecting arm 304 is pushed to a horizontal state. The connecting arm 304 will also push the push plate 301 to slide in the sliding groove 104 and engage with the outer surface of the convex tooth 102, thereby being able to lock the electric bicycle handlebar body 1 in the connecting seat 2 to limit its rotation, thereby realizing the function of automatically locking the electric bicycle handlebar body 1 when the power is off, greatly simplifying the operation steps of locking the vehicle, reducing the tedious process of locking the vehicle, and increasing the reliability of anti-theft.

[0031] According to the above technical solution, the working steps of this solution are summarized and sorted out: when the vehicle is placed after use, the electric bicycle handlebar body 1 of the vehicle will drive the convex teeth 102 on the outer surface to rotate in the connecting seat 2 according to the user's placement position. After the placement is completed, the power is turned off, and the current sensor detects that the current of the battery is lower than the set threshold. It can be judged that the power is turned off and a signal is sent to the controller. The controller controls the micro electric push rod 305 to push the other end of the connecting arm 304 through the piston rod to rotate in the connecting plate 303 of the pushing plate 301 until the connecting arm 304 is pushed. After being pushed to a horizontal state, the connecting arm 304 will also push the pushing plate 301 to slide in the sliding groove 104 and mesh with the outer surface of the convex tooth 102. Since the convex tooth 102 is 360° surrounding, the user can place the faucet body 1 of the electric bicycle at any position and can also get the meshing and locking operation, without the need to swing the faucet position to a dead angle for locking as in the prior art, so that the faucet body 1 of the electric bicycle can be locked in the connecting seat 2 to limit its rotation, thereby realizing the function of automatically locking the faucet body 1 of the electric bicycle when the power is cut off;

[0032] After power is turned on, the current sensor will detect that the current of the battery is greater than the set threshold, and it can be determined that the power is turned on and send a signal to the controller, and the controller will control the micro electric push rod 305 to pull the other end of the connecting arm 304 through the piston rod to rotate in the connecting plate 303 of the push plate 301, and then the push plate 301 can be pulled back in the sliding groove 104 to disengage from the convex tooth 102, thereby completing the purpose of automatic unlocking. This automatic locking design is particularly useful in the application scenario of shared electric bicycles. Users only need to park at any position, and the bicycle will automatically lock the handlebars after power is cut off. There is no need for users to align with a specific position, which greatly improves the user experience and the efficiency of vehicle management. At the same time, it also avoids the vehicle from being correctly locked due to misoperation or negligence of users, thereby increasing the safety and reliability of shared bicycles.

[0033] In summary: the user can place the handlebar body 1 of the electric bicycle at any angle, and it can be automatically locked when the power is cut off. There is no need to swing the handlebar body 1 of the electric bicycle to a specific angle or position, which greatly simplifies the operation steps and reduces the tedious process of locking the bicycle. In addition, since the push plate 301 can allow the convex tooth 102 to rotate to any position to automatically lock the front fork, the situation of failure to lock correctly is avoided, the reliability of anti-theft is increased, and it is ensured that the vehicle can be safely locked under any circumstances.
