Description

Technical Field

[0001] This utility model belongs to the field of intelligent vehicle lock technology, and in particular relates to an intelligent vehicle lock with a fall alarm. Background Technology

[0002] Bicycle locks are a type of security tool used to protect bicycles from theft. With technological advancements, single-function mechanical locks are no longer sufficient to meet the growing practical needs.

[0003] Some middle school students choose to cycle to and from school to shorten their commute time. However, current mechanical locks only function as locks and unlockers, making it difficult to monitor and provide feedback on the cycling status. In case of falls or other accidents, it's difficult to promptly notify parents and provide timely assistance. Therefore, these locks are functionally inadequate and offer unsatisfactory safety. Consequently, there is an urgent need to improve existing bike locks and provide a smart lock with a fall alarm function. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by providing a smart car lock that is reasonably designed, simple in structure, and has positioning, speed measurement, and fall alarm functions, thereby solving the problems existing in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A smart car lock with a fall alarm, comprising:

[0007] The bicycle lock body is fixedly installed on the seat tube of the bicycle, and a photovoltaic power generation panel and a fingerprint touch area are embedded and fixed on the upper surface of the bicycle lock body;

[0008] The controller, fixedly installed inside the vehicle lock body, controls the operation of the vehicle lock body. The controller includes an intelligent lock body unit, a central control unit, a GPS positioning unit, a wireless communication unit, and an attitude sensing unit. The intelligent lock body unit collects fingerprint information recorded in the fingerprint touch area and controls the central control unit to execute the locking and unlocking program. The GPS positioning unit obtains the geographical location information of the vehicle lock and sends the information to the central control unit. The wireless communication unit establishes a communication connection between the central control unit and an external terminal. The attitude sensing unit includes a three-axis accelerometer sensor and a gyroscope to collect the vehicle's acceleration, angle, and spatial attitude data. The central control unit can analyze the data obtained by the attitude sensing unit according to a fall detection algorithm to determine whether the vehicle has fallen.

[0009] The hidden slot is located on one side of the vehicle lock body. Inside the vehicle lock body, a battery for providing power to the vehicle lock is fixedly installed. A charging port electrically connected to the battery is provided on the inner wall of the hidden slot. A rubber sealing sheet is adhered inside the hidden slot. The battery is electrically connected to a photovoltaic power generation panel.

[0010] In a preferred embodiment, the wireless communication unit can control the central control unit to send the geographical location information obtained by the GPS positioning unit to an external terminal, which includes at least one of a smartphone, a smartwatch, and a smart bracelet.

[0011] As a preferred embodiment, the fall detection algorithm specifically includes: setting an acceleration threshold, an angular velocity threshold, and a tilt angle threshold; when the acceleration, angular velocity, and tilt angle are all greater than the set thresholds within an extreme time period, the vehicle is determined to have fallen.

[0012] As a preferred embodiment, the vehicle acceleration data obtained by the attitude sensing unit can also be used to determine the current vehicle speed. When the vehicle speed exceeds the acceleration set threshold and lasts for more than 5 seconds, the central control unit can be controlled by the wireless communication unit to send an overspeed alarm to an external terminal.

[0013] As a preferred embodiment, it also includes an on-site alarm unit, which is electrically connected to the controller. When the controller determines that the vehicle has fallen, the on-site alarm unit can issue an audible and visual alarm signal to obtain timely assistance from passersby.

[0014] In a preferred embodiment, the on-site alarm unit includes a buzzer and an LED warning light.

[0015] In a preferred embodiment, the lock body includes a drive mechanism, a bolt, and a lock body. The drive mechanism is electrically connected to the controller and is used to drive the bolt to extend and retract within the lock body to achieve locking and unlocking.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] In the solution of this utility model:

[0018] The controller uses an internal attitude sensing unit to acquire acceleration, angular velocity and spatial attitude data of the vehicle during riding. The acquired data is compared with a set threshold. When the data exceeds the threshold within an extreme time, it can be determined that the vehicle has fallen. At this time, the GPS positioning unit can be used to obtain the vehicle's geographical location, and the wireless communication unit can be used to control the central control unit to send the acquired geographical location information to the parent's external terminal, so as to facilitate the notification of the parent for timely rescue and enhance safety.

[0019] The vehicle acceleration data obtained by the attitude sensing unit can also be used to determine the current vehicle speed. If the vehicle speed exceeds the acceleration threshold and lasts for more than 5 seconds, an overspeed warning can be sent to the external terminal at the parent's location. This makes it easier to correct the child's unsafe and uncivilized riding behavior. Moreover, when it is determined that the vehicle has fallen, the controller can also control the on-site alarm unit to operate, using a buzzer and LED warning lights to provide on-site audible and visual alarms, making it easy to automatically ask passersby for help.

[0026] The embodiments described below are merely some embodiments of the present invention and do not represent all embodiments consistent with the present invention. Exemplary embodiments will now be described with reference to the accompanying drawings:

[0027] like Figure 1-3 As shown, the smart car lock with fall alarm of this utility model includes:

[0028] The bicycle lock body 1 is fixedly installed on the seat tube of the bicycle. The upper surface of the bicycle lock body 1 is inlaid with a photovoltaic power generation panel 2 and a fingerprint touch area 3.

[0029] The controller 7 is fixedly installed inside the vehicle lock body 1 to control the operation of the vehicle lock body 1. The controller 7 includes an intelligent lock body unit, a central control unit, a GPS positioning unit, a wireless communication unit, and an attitude sensing unit. The intelligent lock body unit is used to collect fingerprint information recorded in the fingerprint touch area 3 and control the central control unit to execute the lock opening and closing program. The GPS positioning unit is used to obtain the geographical location information of the vehicle lock and send the information to the central control unit. The wireless communication unit is used to establish a communication connection between the central control unit and an external terminal. The attitude sensing unit includes a three-axis accelerometer sensor and a gyroscope to collect the vehicle's acceleration, angular velocity, and spatial attitude data. The central control unit can analyze the data obtained by the attitude sensing unit according to the fall judgment algorithm to determine whether the vehicle has fallen.

[0030] Hidden groove 4 is located on one side of the vehicle lock body 1. Inside the vehicle lock body 1, a battery 8 is fixedly installed to provide power to the vehicle lock. A charging port 5 connected to the battery 8 is provided on the inner wall of the hidden groove 4. A rubber sealing sheet 6 is adhered inside the hidden groove 4. The battery 8 is connected to the photovoltaic power generation panel 2.

[0031] Based on the above structure, the wireless communication unit can control the central control unit to send the geographical location information obtained by the GPS positioning unit to an external terminal, which includes at least one of a smartphone, a smartwatch, and a smart bracelet.

[0032] In this embodiment, a communication connection between the central control unit and an external terminal can be established using a wireless communication unit, thereby enabling timely alarms to be sent to the external terminal when the vehicle is speeding or falls over.

[0033] Based on the above structure, the fall detection algorithm specifically includes: setting acceleration threshold, angular velocity threshold and tilt angle threshold. When the acceleration, angular velocity and tilt angle are all greater than the set threshold within an extreme time period, the vehicle is determined to have fallen.

[0034] Based on the above structure, the vehicle acceleration data obtained by the attitude sensing unit can also be used to determine the current vehicle speed. When the vehicle speed exceeds the acceleration set threshold and lasts for more than 5 seconds, the central control unit can be controlled by the wireless communication unit to send an overspeed alarm to the external terminal.

[0035] In this embodiment, the attitude perception unit is used to acquire the vehicle's acceleration, angular velocity, and spatial attitude data, and the data is compared with a set threshold. When the data exceeds the threshold within an extreme time period, it can be determined that the vehicle has fallen. Subsequently, the GPS positioning unit, wireless communication unit, and central control unit can be used to notify the parents for timely rescue, which enhances safety.

[0036] Based on the above structure, it also includes a field alarm unit, which is electrically connected to the controller 7. When the controller 7 determines that the vehicle has fallen, the field alarm unit can issue an audible and visual alarm signal to obtain help from passersby in a timely manner.

[0037] Based on the above structure, the on-site alarm unit includes a buzzer and an LED warning light.

[0038] In this embodiment, when the vehicle falls over, a buzzer and LED warning lights can be used to provide an on-site audible and visual alarm, making it convenient to automatically seek help from passersby.

[0039] Based on the above structure, the lock body 1 includes a drive mechanism, a bolt, and a lock body. The drive mechanism is electrically connected to the controller 7 and is used to drive the bolt to extend and retract within the lock body to achieve locking and unlocking.

[0040] In this embodiment, once the fingerprint verification is successful, the lock can be automatically opened and closed using the lock body 1, eliminating the need for a mechanical key and making the locking and unlocking process more convenient.

[0041] The working principle of this utility model is as follows:

[0042] When in use, the user's fingerprint is first verified through the fingerprint touch area 3. After successful verification, the controller 7 can control the lock body 1 to automatically lock and unlock. During the ride, the attitude sensing unit inside the controller 7 can acquire the acceleration, angular velocity and spatial attitude data of the vehicle. The acquired data is compared with the set threshold. When the data exceeds the threshold in a very short time, it can be determined that the vehicle has fallen. At this time, the GPS positioning unit can be used to obtain the geographical location of the vehicle, and the wireless communication unit can be used to control the central control unit to send the acquired geographical location information to the external terminal of the parent. This facilitates the notification of the parent to provide timely assistance and enhances safety. In addition, the vehicle acceleration data obtained by the attitude sensing unit can also be used to determine the current speed. When the speed exceeds the acceleration set threshold and lasts for more than 5 seconds, an overspeed warning can also be sent to the external terminal of the parent. This makes it convenient to educate the child and correct the child's unsafe and uncivilized riding behavior when the child arrives home.

[0043] When the vehicle is judged to have fallen, the controller 7 can also control the operation of the on-site alarm unit, and use the buzzer and LED warning light to provide on-site sound and light alarm, so as to automatically ask passers-by for help. The battery 8 can provide power for the operation of the lock, and the photovoltaic power generation panel 2 can be used to replenish the power of the battery 8. At the same time, when the photovoltaic power generation panel 2 is not charged enough, the charging port 5 provided by the lock can also be connected to an external power source for charging. When the charging port 5 is not in use, the rubber sealing sheet 6 can be inserted into the hidden groove 4 to achieve dustproof and rainproof protection for the charging port 5.

[0044] It should be noted that all electrical components in this device are existing electrical elements, and their specific circuit layout and principles are mature technologies, so they will not be described in detail.

[0045] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Any equivalent changes, modifications, substitutions, and variations made by those skilled in the art based on the concept of this utility model and on the basis of existing technology through logical analysis, reasoning, or limited experiments shall be within the scope of protection defined by the claims.
