Technical Field
[0001] The utility model relates to the technical field of bicycle anti-theft, in particular to a hidden anti-theft device for an electric-assisted bicycle. Background Art
[0002] A power-assisted bicycle is a new type of two-wheeled vehicle, a type of bicycle. It uses a battery as an auxiliary power source, is equipped with a motor, and has a power-assist system. It is a new type of transportation tool that can integrate human riding and motor assistance. In the field of power-assisted bicycles, there are mainly two types of motor installation positions. One is mid-mounted, that is, the motor is installed in the middle position of the vehicle body, that is, the motor at the five-way position, called a mid-mounted motor. The mid-mounted motor is connected to the frame and is connected to the rear wheel through a chain to transmit power. At the same time, pedals are installed on both sides of the motor. When the motor has no power supply, the rider can achieve human riding by pedaling, and the resistance is no different from that of a normal bicycle.
[0003] Generally, in order to protect the safety of their property, bicycle owners will equip their bicycles with anti-theft devices, namely anti-theft locks. There are many types of anti-theft locks on the market. Among them, there is a circular lock with excellent performance and high stability. However, since it affects the appearance of the bicycle after installation, it is criticized by many people or even abandoned. For this reason, we propose a hidden anti-theft device for electric power bicycles. Utility Model Content

[0015] In summary, the utility model mainly has the following beneficial effects:
[0016] 1. The utility model sets a fixing block, a connecting block, a mounting part and a rotating shaft. First, the mounting part of the anti-theft lock is sleeved on the adjusting rod at the bottom of the seat cushion, and then the lock tongue can be pulled to move the rear wheel to limit the position of the rear wheel for theft prevention. When opening, only the key needs to be inserted into the control switch and twisted to reset the lock tongue for unlocking. Furthermore, when the anti-theft lock is not in use, the anti-theft lock is rotated upward, and the anti-theft lock will rotate to the bottom of the seat cushion under the action of the rotating shaft, so as to achieve its concealment, improve the aesthetics of the bicycle, and meet the requirements of users.
[0017] 2. The utility model provides a locking rod, a rotating disk, a locking block, a sliding groove, a sliding block and a reset spring. When the anti-theft lock is hidden and stored, the rotation of the anti-theft lock will synchronously drive the rotating disk to rotate. After the rotating disk rotates, the locking rod on its outer wall will be driven to rotate. When the locking rod rotates to contact the locking block, it will squeeze the locking block to move outward and make the locking block stretch the reset spring. When the locking rod moves to the side of the locking groove on the inner side of the locking block, the locking block will immediately reset under the action of the reset spring, thereby realizing the locking limit of the locking rod, that is, realizing the limit of the rotating shaft, and also realizing the limit of the anti-theft lock, thereby ensuring the stability of the anti-theft lock when it is hidden and stored.

[0026] Furthermore, in this embodiment, the rotating shaft 7 is rotatably connected to the inner wall of the connecting block 6 via a bearing, and the outer wall of the rotating shaft 7 is fixedly sleeved to the inner wall of the fixing block 4 .
[0027] See also Figure 3 , discs 8 are fixed on the outer walls of the connecting block 6 at both ends of the rotating shaft 7, and the disc 8 is slidably connected to the outer wall of the connecting block 6. Two groups of engaging rods 9 are symmetrically arranged on the outer wall of the disc 8, and the ends of the two groups of engaging rods 9 are both arranged in arc shapes to assist the engaging of the engaging rods 9 with the engaging block 12.
[0028] See also Figure 3 A locking block 10 is installed on the outer wall of the connecting block 6 in the rotation direction of the locking rod 9, and a locking groove adapted to the locking rod 9 is opened on the inner side of the locking block 10, and a lever 11 extending upward is fixed to the top of the locking block 10 to achieve the locking and limiting effect of the locking rod 9, that is, to achieve the limiting effect of the rotating shaft 7.
[0029] See also Figure 3-4 The end surface of the connecting block 6 is located at the bottom end of the locking block 10 and is provided with a slide groove 12, and a slider 13 is slidably connected in the inner wall of the slide groove 12 and is fixedly connected to the top end and the bottom end of the locking block 10. The slider 13 is connected to a return spring 14 installed on the inner wall of the slide groove 12 to realize the movement and return of the locking block 10.
[0030] The working principle of the utility model is as follows: first, the mounting portion 5 of the anti-theft lock is sleeved on the adjustment rod at the bottom of the seat cushion, and then the lock tongue 2 can be pulled to move the rear wheel to limit the position of the rear wheel for anti-theft.
