Description

Technical Field

[0001] This utility model belongs to the field of logistics box technology, and in particular relates to a trigger-type low battery warning device for an electronic locator of a logistics box. Background Technology

[0002] With the rapid development and progress of the logistics industry, the usage of logistics boxes has shown a year-on-year upward trend. At the same time, users' demands for logistics timeliness are constantly increasing, making the installation of positioning devices on logistics boxes a real need. Currently, traditional positioning devices mainly include mobile electronic devices equipped with positioning chips. In order to accurately locate logistics boxes in real time, these mobile electronic devices must continuously provide stable power to the positioning chip and other loads. Furthermore, to ensure that the electronic devices remain in normal working condition, the system periodically checks the power level of the electronic devices. During the check, if insufficient power is detected, the system will immediately issue an alarm to ensure the safety of the logistics box and the accuracy of its positioning. Currently, traditional low-power alarm methods mainly include two types: one is to use a display, such as an LCD screen, to show the signal; the other is to use an audible alarm, such as a speaker and buzzer, for voice warning. However, in practical applications, it has been found that these two traditional alarm methods have certain limitations. Specifically, once a power outage occurs, or when the power drops to a level that cannot support the operating current requirements of the display and audible alarm, these warning messages will immediately disappear, failing to continue conveying necessary warning information to the user. Utility Model Content

[0003] To address the problems existing in the prior art, this utility model provides a trigger-type low battery warning device for electronic locators of logistics boxes. When the electronic locator on the logistics box is low on power, it can provide timely warnings. At the same time, the warning information can be saved in the event of a power outage.

[0004] The technical solution adopted in this utility model is as follows:

[0005] A trigger-type low battery warning device for an electronic locator of a logistics box includes:

[0006] The base has a first groove on its upper surface and a second groove at the bottom of the first groove; a cylindrical protrusion is provided on the upper surface of the first groove.

[0007] A coil connected to a trigger power supply, the coil being mounted in a second groove, and the central axis of the coil being perpendicular to the bottom surface of the second groove;

[0008] A rotating rod, the rotating rod including a magnetic core power rod inserted into the coil, the upper end of the magnetic core power rod being connected to a drive rod;

[0009] The warning component is located on the upper surface of the first groove. The warning component has a circular hole that mates with the protrusion and an oblong hole that mates with the drive rod. The warning component is provided with a warning color block.

[0010] A cover plate is installed on the upper surface of the base, and a viewing window is provided on the cover plate.

[0011] Preferably, the drive rod includes a horizontal rod parallel to the first groove and a slide rod perpendicular to the first groove. One end of the horizontal rod is fixedly connected to the upper end of the magnetic core power rod, and the other end of the horizontal rod is fixedly connected to the lower end of the slide rod.

[0012] Preferably, the magnetic core power rod, the horizontal rod, and the slide rod are integrally formed.

[0013] Preferably, the slide bar and the elongated hole are in a clearance fit.

[0014] Preferably, the outer diameter of the magnetic core power rod is smaller than the inner diameter of the coil.

[0015] Preferably, the central axis of the circular hole and the long axis of the oblong hole are located in the same plane.

[0016] Preferably, the protrusion and the circular hole are in a clearance fit.

[0017] Preferably, the warning component includes a rectangular outer frame for attaching warning sign blocks, and the outer frame has a groove or through hole for engaging the warning sign blocks.

[0018] Preferably, the viewing window is a transparent glass window.

[0019] Preferably, the window is a through hole.

[0020] Compared with the prior art, the advantages and positive effects of this application are:

[0021] In traditional electronic locator technology for logistics boxes, when the locator's battery level drops to low, a power source is triggered, sending an initiation current to the display and / or alarm. Upon receiving this current, the display and / or alarm activate, performing their alarm functions. However, this mechanism has a significant drawback: once the trigger power is cut off, the display and / or alarm cease operation, resulting in the loss of previously accumulated alarm information. Specifically, the display will no longer show low battery warnings, and the alarm will stop emitting any alarm signals.

[0022] To address this issue, this invention proposes an improved technical solution. In this solution, when the electronic locator on the logistics box detects insufficient power, the triggered power supply sends a starting current to a coil. The magnetic core drive rod in the coil begins to rotate under the influence of the induced current, which in turn drives a drive rod to rotate. This drive rod then drives a warning component, causing it to rotate around a protrusion as its fulcrum. Guided and limited by an elongated hole, the warning component moves a warning indicator color block to a specific viewing window position. Workers can check for the presence of the warning indicator color block through this window. If the warning indicator color block appears in the window, it means the power is insufficient and the battery needs to be charged or replaced promptly. Conversely, if no warning indicator color block appears, it indicates sufficient power and there is no need to worry. Even if the trigger power supply fails in this case of insufficient power, the electromagnetic induction force between the coil and the magnetic core drive rod will disappear, causing the magnetic core drive rod to stop rotating. However, since the warning indicator color block has already been moved to the viewing window position, it will remain there and will not disappear due to the power failure. In this way, even in the event of a power outage, staff can still see the warning indicator blocks through the viewing window, thus ensuring that alarm information is not lost.

[0032] Please see Figures 1 to 5 A trigger-type low battery warning device for an electronic locator of a logistics box, comprising:

[0033] The base 1 has a first groove 1-1 on its upper surface. The first groove can be rectangular or circular. The bottom of the first groove is flat. Then, a second groove 1-2 is formed at the bottom of the first groove 1-1. The second groove can also be rectangular or circular. The bottom of the second groove is flat. A cylindrical protrusion 1-3 is provided on the upper surface of the first groove. The base and the protrusion can be integrally formed, or a threaded hole can be first formed on the upper surface of the first groove, and an external thread can be provided at the lower end of the protrusion. The two are connected by threads.

[0034] A coil 3 connected to a trigger power supply is installed in a second groove, with its lower surface adhered to the second groove, and the central axis of the coil 3 perpendicular to the bottom surface of the second groove; since the trigger power supply is existing technology, it will not be described in detail here.

[0035] Rotating rod 4, the rotating rod 4 includes a magnetic core power rod 4-1 inserted into the coil 3. When the trigger power supply supplies power to the coil 3, the magnetic core power rod begins to perform rotational motion under the action of electromagnetic induction. The upper end of the magnetic core power rod is connected to a drive rod, and the drive rod is L-shaped in whole.

[0036] The warning component is located on the upper surface of the first groove. The warning component has a circular hole 2-1 that mates with the protrusion and an oblong hole 2-2 that mates with the drive rod. The warning component is provided with a warning color block 5. In order to reduce friction, the protrusion and the circular hole are fitted with a clearance.

[0037] Cover plate 6 is installed on the upper surface of base 1, and a viewing window 6-1 is provided on cover plate 6; cover plate 6 and base 1 can be fixed with bolts or screws.

[0038] To better understand the technical solution, the following is a non-limiting explanation:

[0039] The drive rod includes a horizontal rod 4-2 parallel to the first groove and a slide rod 4-3 perpendicular to the first groove. One end of the horizontal rod is fixedly connected to the upper end of the magnetic core power rod, and the other end of the horizontal rod is fixedly connected to the lower end of the slide rod.

[0040] To improve structural strength, the magnetic core power rod, horizontal rod, and slide rod are integrally formed.

[0041] The slide bar and the oblong hole are fitted with a clearance.

[0042] The outer diameter of the magnetic core power rod is smaller than the inner diameter of the coil 3.

[0043] The central axis of the circular hole and the long axis of the oblong hole are located in the same plane.

[0044] The warning component includes a rectangular outer frame 2, on which a groove or through hole is provided for engaging the warning sign color block 5.

[0045] The viewing window can be a transparent glass window, or it can be a through hole instead of transparent glass.

[0046] Working principle:

[0047] First, the same steps as traditional technology include: before using the logistics box, ensure that the power supply meets the requirements, and then start the electronic locator. At this time, the power supply enters the working state and continuously provides working current to the electronic locator and other loads. The power sensor in the electronic locator detects the remaining power of the power supply in real time or at regular intervals. When the remaining power of the power supply is lower than the threshold, it triggers the power supply to send an alarm prompt to the alarm device.

[0048] To prevent the alarm message from disappearing after a power outage, this invention employs the following steps: A trigger power source sends a working current to the coil in the low battery warning device. This generates a magnetic field, causing the magnetic core rod within the coil to rotate under the influence of the magnetic field. This rotation drives the horizontal rod and the slide rail. During this movement, the slide rail rotates the warning component, causing it to rotate around a protrusion as its fulcrum. Guided and limited by the oblong hole, the warning component moves the warning indicator color block to the viewing window position and stops. When a power outage occurs, the current in the coil disappears, the magnetic field disappears, and the magnetic core rod loses its rotational power, leaving the warning indicator color block still stationary in the viewing window position.

[0049] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model are included within the scope of protection of this utility model.
