Description

Technical Field

[0001] The present invention relates to the field of robots, and in particular to a rapid startup and sleep device based on a magnetic switch. Background Art

[0002] This invention is used for a fast startup and sleep device for a water rescue robot (application number: 201930312306.4). Due to special requirements, water rescue robots require a fast startup response. Furthermore, because water rescue robots operate in harsh environments, a device with strong anti-interference capabilities, battery conservation, and increased standby time is required.

[0003] The invention patent with application number 2018109704963 discloses a wake-up and sleep circuit for a Hall switch, which includes a controlled circuit, a Hall switch, a magnetic component, and a single-chip microcomputer. The power input terminal of the Hall switch is connected to the power supply, the signal output terminal of the Hall switch is connected to the signal input terminal of the single-chip microcomputer, and the signal output terminal of the single-chip microcomputer is connected to the controlled circuit. The Hall switch senses the magnetic component and outputs a first level signal when the magnetic induction intensity reaches a preset magnetic intensity value, and outputs a second level signal when the magnetic induction intensity is lower than the preset magnetic intensity value. When the single-chip microcomputer receives the first level signal output by the Hall switch, it controls the controlled circuit to sleep, and when it receives the second level signal output by the Hall switch, it controls the controlled circuit to work. The present invention can solve the problem of high power consumption of existing solar lamps when they are stored or in standby mode. However, the above patent has the following defects: the above patent needs to output multiple signals, which increases the cost. When used in a complex electromagnetic environment, it is extremely susceptible to interference and fluctuations of the external electromagnetic field, which will affect the magnetic induction intensity and thus affect the signal output. The reliability is not high and it cannot be used in environments such as mud and sand. Summary of the Invention

[0042] The present invention will be described in detail below with reference to specific embodiments. The following examples will help those skilled in the art to further understand the present invention, but are not intended to limit the present invention in any form. It should be noted that, for those skilled in the art, several changes and improvements can be made without departing from the scope of the present invention. These all fall within the scope of protection of the present invention.

[0043] like Figures 1 to 4 The magnetic switch-based quick power-on and power-off device provided by the present invention includes an injection-molded housing 4, a switch housing 6, a rubber plug 1, a magnetic relay switch 5, and a circuit to be controlled, wherein the magnetic relay switch 5 controls the on / off of the circuit to be controlled. The switch housing 6 is mounted on the injection-molded housing 4 and includes a slot for receiving the rubber plug 1. The magnetic relay switch 5 is mounted on the switch housing 6. A sealing ring 2 is provided on the outer periphery of the rubber plug 1. The rubber plug 1 is provided with a perforation through which a rope is passed. A strong magnet is mounted within the rubber plug 1. When the rubber plug 1 is inserted into the slot, the strong magnet 3 acts on the magnetic relay switch 5, thereby controlling the on / off of the circuit to be controlled. When the rubber plug 1 is inserted into the slot, the strong magnet 3 approaches the magnetic relay switch 5, closing the magnetic relay switch 5. When the rubber plug 1 is removed from the slot, the strong magnet 3 moves away from the magnetic relay switch 5, opening the magnetic relay switch 5. The strong magnet 3 and the magnetic relay switch 5 do not contact each other. When the magnetic relay switch 5 is closed, the circuit to be controlled is in the working state; when the magnetic relay switch 5 is opened, the circuit to be controlled is in the dormant state; or when the magnetic relay switch 5 is closed, the circuit to be controlled is in the dormant state; when the magnetic relay switch 5 is opened, the circuit to be controlled is in the working state.

[0044] Furthermore, the switch housing 6 is provided with a flange on its outer periphery. The injection-molded housing 4 is provided with a housing mounting hole. The switch housing 6 extends into the housing mounting hole, with the flange surface resting against the surface surrounding the housing mounting hole. The portion of the switch housing 6 extending into the housing mounting hole is provided with threads on its outer side. The switch housing 6 is secured to the injection-molded housing 4 via the flange and a nut 7 that matches the threads.

[0045] The working principle of the present invention is as follows: Figure 4 For example, when the rubber plug 1 is inserted into the switch housing 6, the strong magnet 3 and the magnetic relay switch 5 gradually approach each other. When the magnetic induction intensity exceeds the threshold, the magnetic relay switch 5 is in the normally closed state. At this time, the circuit board 10 controls the device to enter the dormant state with the lowest energy consumption.

[0046] The rope hole on the rubber plug 1 is fixed to the bracket by a rope. When the device is removed from the bracket, the rope plug 1 is pulled out of the switch housing 6. At this time, the strong magnet 3 and the magnetic relay switch 5 are gradually separated due to the distance. When the magnetic induction intensity is lower than the threshold, the magnetic relay switch 5 is in the normally open state. At this time, the circuit board 10 energizes all components, putting the device into working state.

[0047] The present invention switches the device between the power-on and standby states through a magnetic switch, has a rapid response and high reliability when powered on, and saves battery energy and increases the standby time when in standby mode.

[0048] The above describes specific embodiments of the present invention. It should be understood that the present invention is not limited to the specific embodiments described above, and those skilled in the art may make various changes or modifications within the scope of the claims, which do not affect the essence of the present invention. The embodiments of this application and the features in the embodiments may be combined with each other in any manner unless there is a conflict.
