Detailed Description

Referring to fig. 1 to 4, a bicycle anti-theft alarm device 1 is disclosed, which comprises a battery 101, a control chip 102, an alarm unit 103 and a sensor 104, and is mounted on a bicycle front fork 200, wherein: the battery 101 is electrically connected to the control chip 102, the alarm unit 103 and the sensor 104; the control chip 102 is respectively in signal connection with the sensor 104 and the alarm unit 103; when the sensor 104 detects a shock, it sends a detection signal to the control chip 102, and the control chip 102 sends an alarm signal to the alarm unit 103 for operation.

In the embodiment, the battery 101, the control chip 102 and the sensor 104 are mounted inside the front fork 200 (in the left side of the drawing) through the cover seat 110, and the alarm unit 103 is mounted inside the head tube 210 of the front fork 200 through the concealed seat 120, so most of the structure of the present invention is located inside the front fork 200. In addition, the alarm unit 103 is electrically connected to the control chip 102 and the battery 101 by wire sets, and since the bicycle is provided with brake lines and even front fork damping adjustment lines at the position of the front fork 200, the difference between the wire sets and the lines is not easily distinguished by a thief. The cover base 110 is assembled with a circuit board 105 for fixing the control chip 102 and the sensor 104, and is electrically connected to the battery 101, the alarm unit 103 and the sensor 104 through the circuit board 105.

The sensor 104 is an accelerometer, which is also called an accelerometer, an acceleration sensor, or a gravitational acceleration sensor. The alarm unit 103 is a speaker, for example, so the alarm unit 103 is operated to emit sound. The concealed seat 120 is generally a hollow barrel-shaped structure, and has an opening at the bottom thereof, through which the wire set is provided to penetrate and the sound generated by the operation of the alarm unit 103 can be transmitted outwards.

When the bicycle anti-theft alarm device 1 is actually operated, when a thief pulls or rides the bicycle, the sensor 104 detects the vibration of the bicycle and sends a detection signal to the control chip 102, the control chip 102 sends an alarm signal to the alarm unit 103 for operation, and the alarm unit 103 sends a sound to remind surrounding people to pay attention, so that the thief usually escapes from a scene in a hurry at a moment, the bicycle is prevented from being stolen, and the anti-theft alarm effect is achieved. And the utility model discloses install in bicycle front fork 200 positions to the tradition additionally installs the outside tool to lock pattern in the bicycle, consequently has the hidden difficult quilt of structure to perceive the effect by the thief.

The utility model discloses thief-proof warning device 1 of bicycle further includes switch 106, this battery 101 of this switch 106 electric connection for control this battery 101 output with not export in this control chip 102, this alarm unit 103, this sensor 104. In order to switch the operation of the anti-theft alarm device 1 between on and off states, i.e. during normal riding or home storage, the switch 106 (the switch 106 is a push switch, for example) can be directly operated manually to switch the on operation and the off operation of the anti-theft alarm.

The anti-theft alarm device 1 for bicycle of this embodiment further comprises a charging port 107 electrically connected to the battery 101, and the charging port 107 is for example a USB connector, and the battery 101 is charged after the connector for providing external power through the charging port 107 is inserted. The charging port 107 partially fixes the circuit board 105, penetrates the top position of the cover base 110 to be partially exposed, and is additionally sleeved with the cover 108 at the position of the charging port 107 at the exposed part, so as to prevent dust, foreign matters and water from entering the charging port 107 to influence the charging operation.

The utility model discloses thief-proof alarm device 1 of bicycle further includes bluetooth antenna 109 and this control chip 102 of electric connection, in addition with mobile device 300 through this bluetooth antenna 109 and the two-way wireless signal connection of this control chip 102. Through the mobile device 300, the switching between the on operation and the off operation of the warning device can be performed under remote wireless operation, so as to provide another option for the user to operate the device. The bluetooth antenna 109 is disposed on the circuit board 105. The mobile device 300 may be a smart phone, a notebook computer or a tablet computer, and is exemplified by a smart phone.

Referring to fig. 5, the mobile device 300 (including the operation interface 310, the operation interface 310 includes a battery power pattern 311, a bluetooth pattern 312, an on alert pattern 313, an off alert pattern 314, and a setting pattern 315. The operation interface 310 of the mobile device 300 is used to turn on and off the device, for example, when the on alert pattern 313 is operated and the operation is triggered, the alarm unit 103 sounds for 20 seconds and then pauses for 10 seconds to cycle until the off alert pattern 314 is operated and the alarm unit 103 stops sounding, the battery power pattern 311 shows the current remaining power of the battery 101, the bluetooth pattern 312 provides the on operation and the off operation stop of the bluetooth communication for operating the mobile device 300, and the setting pattern 315 changes/sets the connection password between the mobile device 300 and the device.

The electronic device further includes a damping adjustment set 220 electrically connected to the battery 101, and the control chip 102 sends a damping adjustment signal to the damping adjustment set 220 when sending the warning signal, so that the damping adjustment set 220 operates to change the damping response of the front fork 200. As shown in fig. 6 to 9, when the motor 221 of the damping adjustment set 220 operates, the valve rod 222 is indirectly driven to displace along the axial direction of the front fork 200, so that the valve rod 222 forms the closed flow passage 223 and the open flow passage 223, and thus the fluid (here, damping oil is taken as an example) cannot flow and smoothly flows, and a locked state of the front fork 200 (i.e. the front fork 200 has no damping effect, and the upper tube 230 and the lower tube 240 of the front fork 200 cannot displace axially relative to each other as shown in fig. 6 and 7) and an unlocked state of the front fork 200 (providing a damping effect, and the upper tube 230 and the lower tube 240 of the front fork 200 can displace axially relative to each other within a limited range as shown in fig. 8 and 9) are respectively formed.

For example, when the front fork 200 is unlocked, the front fork 200 is continuously operated to absorb a part of the force during the pedaling process of a thief, and a large amount of physical power is required to be consumed. Or when the road surface is not paved (stone road, dirt road or mixed stone and mud road), the locking state of the front fork 200 is set (the shock-absorbing operation cannot be provided, and the upper tube 230 and the lower tube 240 of the front fork 200 cannot axially displace relatively), so that the bicycle is not easy to operate when riding on a rugged road surface. In other words, the damping adjustment set 220 is operated to change the damping state of the front fork 200, so as to delay the theft of the bicycle or shorten the theft distance, thereby increasing the possibility of real-time recovery. The operator interface 310 of the mobile device 300 may also be operated to perform the damping response of the damping adjustment set 220, for example, in the setting diagram 315.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any way, and all simple modifications, equivalent changes and modifications made by the technical spirit of the present invention to the above embodiments still fall within the scope of the technical solution of the present invention.
