AI Technical Summary
Existing fall alarms for the elderly suffer from high component costs, low detection accuracy, and low reliability.
Adopting a wearable design, it uses a conductive metal bead to slide and connect a contact point when the elderly person falls, directly controlling the power supply of the alarm unit and issuing an alarm. This simplifies the design to a mechanical structure and avoids the use of electronic detectors.
This reduces component costs, improves the accuracy and reliability of alarms, and ensures that the elderly receive timely assistance.

TECHNICAL FIELD
[0001] The present application relates to a wearable old people fall alarm, belongs to the technical field of alarm, especially an alarm that can automatically send out an alarm after the old people fall. BACKGROUND
[0002] Fall is the number one killer of accidental injury of old people, there are many old people falling in our country every year, and the consequences are very serious if the old people falling cannot be treated. For this reason, there are various old people falling alarms on the market, which are used to send out an alarm after the old people fall, attract the attention of outsiders and provide help, and the falling alarm plays a positive role. The fastest rescue after the old people fall is the best solution to avoid more serious injuries. The working principle of various old people falling alarms on the market is to collect information through electronic detectors or sensors to determine whether the old people fall, and then instruct the controller to control whether to start the alarm, which has the following disadvantages: 1. The more electronic parts, the higher the cost; 2. The accuracy of the information collected by the electronic detector or sensor is affected by many factors, and the accuracy directly affects the actual use effect; 3. There is no any part with 100% qualified rate in reality, and the qualified rate is lower when multiple parts are combined, and theoretically the more electronic parts, the higher the probability of failure; SUMMARY
[0003] In order to overcome the above shortcomings of the existing old people falling alarm, the present application provides a wearable old people falling alarm, which is worn on the waist or arm of the old people, and the sliding of the conductive metal beads in the trigger is used to control whether to start the alarm. When the old people fall, the kinetic energy generated by the conductive metal beads in the trigger or the gravity of the conductive metal beads under the action of the kinetic energy makes the two contact points of the trigger connected, so as to connect the power supply of the alarm unit and then send out an alarm, the alarm form: sound alarm or light alarm or combination of sound alarm and light alarm, so as to attract the attention of outsiders and provide help, so that the old people falling can get the fastest rescue. The simpler the way, the more reliable the technical solution is.
[0004] The technical scheme adopted by the present application to solve its technical problems is: a wearable old people fall alarm, comprising: a shell, an alarm unit, a power line, a battery and a trigger, characterized in that: the alarm unit, the power line, the battery and the trigger are installed in the shell, the alarm unit, the battery and the trigger are connected by three power lines, one of which connects the alarm unit and the battery, the second connects the battery and the contact two, and the third connects the contact one and the alarm unit, the trigger is responsible for controlling whether the alarm unit sends an alarm, and the battery is responsible for providing power; the trigger is composed of: a shell, a contact one, a contact two and a conductive metal bead, the contact one, the contact two and the conductive metal bead are installed in the shell, the contact one and the contact two are in a disconnected state under normal circumstances or when the old people do not fall, and the conductive metal bead is slidable within the design range, when the old people fall, the conductive metal bead slides under the action of kinetic energy generated when the old people fall or the gravity of the conductive metal bead itself, so as to connect the two contacts in the trigger, thereby connecting the power supply of the alarm unit and further sending an alarm. When the old people get up or are helped up, the conductive metal bead slides under the action of its own gravity, so as to disconnect the two contacts in the trigger, thereby turning off the alarm function; the alarm unit alarm form: sound alarm or light alarm or combination alarm of sound alarm and light alarm, the battery is a disposable battery or a rechargeable battery.
[0005] The beneficial effects of the present application are: 1. Simple and direct mechanical technical scheme is used to replace electronic detectors or sensors to determine whether the old people have fallen, thereby saving part cost; 2. Simple and direct mechanical technical scheme is used to avoid false positives or false negatives of electronic sensors, thereby improving alarm accuracy; BRIEF DESCRIPTION OF DRAWINGS

[0011] Embodiment:
[0012] The present application is a wearable fall alarm for the elderly, so the alarm needs to be fixed on the body of the elderly with a strap. Since it is common sense and not the key point of the technical solution, the technical parameters such as the material of the strap will not be discussed here. In order to better illustrate the technical solution, the following common sense settings are made: 1. The conductive metal beads 9 have a conductive function; 2. The conductive metal beads 9 will not connect the contact point one 7 and the contact point two 8 when the elderly are walking normally or have not fallen, which is a common sense technology in the industry. Technical solution: a wearable fall alarm for the elderly, comprising: a shell 1, an alarm unit 2, a power cord 3, a battery 4 and a trigger 5, characterized in that: the alarm unit 2, the power cord 3, the battery 4 and the trigger 5 are installed in the shell 1, the alarm unit 2, the battery 4 and the trigger 5 are connected by three power cords 3, one of which connects the alarm unit 2 and the battery 4, the second connects the battery 4 and the contact point two 8, and the third connects the contact point one 7 and the alarm unit 2. The trigger 5 is responsible for controlling whether the alarm unit 2 sends an alarm, and the battery 4 is responsible for providing power; the trigger 5 is composed of: a shell 6, a contact point one 7, a contact point two 8, and a conductive metal bead 9, the contact point one 7, the contact point two 8 and the conductive metal bead 9 are installed in the shell 6, the contact point one 7 and the contact point two 8 are in a disconnected state under normal circumstances or when the elderly have not fallen, and the conductive metal bead 9 is slidable within the design range.
