Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to an automatic falling-off device for a charging gun of an ambulance. Background Art

[0002] Ambulances are widely used first aid tools. Given that they are used in most emergencies, they must be ready and available at all times. However, ambulances now use an increasing number of first aid and communication devices, and the power supply for these devices, which relies solely on the vehicle's own battery, is no longer sufficient for practical use. Therefore, dedicated batteries are installed and can be charged via an external power source. When the ambulance is on standby, the ambulance's functional battery / storage battery can be charged using mains electricity.

[0003] This charging design, which better suits the actual use of ambulances, requires an external charging gun and plug to be plugged into the charging port. For ease of use and quick charging, the charging port is preferably located on the vehicle's exterior wall. The charging plug does not have an additional lock, and the plug and socket simply use a static fit. However, when an emergency requires the use of the vehicle, the driver may forget to unplug the charging gun and drive away, potentially damaging the gun tip or severing the wire, posing a safety hazard.

[0004] In summary, the charging interface and wiring design of existing ambulances have technical problems that are easily damaged during use and cause safety hazards. Utility Model Content

[0007] The utility model provides an automatic detachment device for an ambulance charging gun, in which a reduction gearbox is arranged at a position on the side wall of the ambulance for plugging in the charging gun, and the reduction gearbox is arranged on the inner side wall of the ambulance, and a push-out shaft is passed through the reduction gearbox, and the push-out shaft is matched with the reduction gear group in the reduction gearbox, and the position where the end of the push-out shaft is facing is the end position of the charging gun, and the reduction gear group is matched with an output motor, which outputs a rotational motion through the output motor, and drives the axial feed of the push-out shaft through the reduction transmission of the reduction gear group to reach a position that abuts against the end of the charging gun. Further feed of the push-out shaft can push and disengage the charging gun from the charging position plugged in on the side wall of the ambulance, and the start control of the output motor can be achieved by manual operation of the user, or more conveniently, it can be automatically triggered by other means, as long as the charging gun is detached when the ambulance is in motion. This design can automatically, simply and quickly detach the charging structure from the ambulance, effectively avoiding damage to the plug and wiring used for charging when the ambulance is temporarily driven.

[0008] As a preferred solution, it also includes a plug-in charging shell fixedly set on the side wall of the ambulance, and a charging groove with a shape that matches the shape of the plug of the charging gun is provided on one side of the plug-in charging shell. The reduction gear box is fit and fixed to the other side of the plug-in charging shell, and the plug-in charging shell is provided with a through-hole structure for the ejection shaft to extend into at the axial end position corresponding to the ejection shaft.

[0009] This design provides an optimal charging matching design. A plug-in charging shell for directly plugging into the plug of the charging gun is set at the plug-in position of the charging gun and the side wall of the ambulance. The plug-in charging shell is provided with a charging groove on one side of the outer wall of the ambulance. The shape of the charging groove can match the concave and convex part of the plug of the charging gun. The reduction gear box is fittedly installed on the other side of the plug-in charging shell. The through-hole structure on the plug-in charging shell can accommodate the ejection shaft to pass through it so as to push out the charging gun plugged in the charging groove.

[0010] As a preferred solution, the reduction gear set includes an output gear and a main gear that mesh with each other. The output gear is sleeved on the output shaft of the output motor, and the main gear is sleeved on the outer circumference of the ejection shaft. The outer circumference of the main gear is a lead screw structure, and the center hole of the main gear is provided with an internal thread structure. The output shaft and the main gear engage with each other via a nut and lead screw structure. This design provides a preferred reduction gear set structure, which consists of two meshing gears, one of which directly engages with the output motor, and the other gear engages with the ejection shaft via a threaded lead screw structure. This design has a simple structure and stable and effective transmission.

[0011] As a preferred solution, the output gear and main gear are helical gears arranged axially perpendicular to each other, and the output motor is mounted and fixed to the outer wall of the reduction gearbox. Based on the above structural design, the spatial distribution of the two gears is optimized. The two gears are perpendicular to each other and both are helical gears, which effectively saves space within the reduction gearbox.

[0012] As a preferred solution, the charging gun's plug is provided with a circular groove opposite the end of the ejection shaft, designed to abut against the end of the ejection shaft. This design further optimizes the charging gun's structure by providing a circular groove on the end of the plug, effectively preventing the end of the ejection shaft from scratching the charging gun surface and preventing slipping during the push process.

[0013] As a preferred solution, the edge of the opening of the charging groove that plugs into the charging housing is provided with a stepped structure. This design optimizes the shape of the charging groove and provides a stepped structure at the edge of its opening end, which can limit the insertion depth of the charging gun during charging and ensure the firmness of the plug-in.

[0014] As a preferred solution, the output motor is electrically connected to a signal trigger module, which is connected to the ambulance's ignition starter signal. The ignition starter triggers the output motor. This design further improves the automated control of the charging gun's release, allowing the charging gun to be easily released by triggering the ejection shaft when the vehicle starts, making the charging gun's release fully automated and more convenient.
