Description

Technical Field

[0001] The utility model relates to the technical field of intelligent robots, and particularly to an automatically guided mobile charging chassis with a split design. Background Technique

[0002] Automated Guided Vehicle, abbreviated as AGV, refers to an unmanned automated vehicle with automatic guiding devices such as magnetic strips, tracks or lasers, traveling along a pre-planned path, powered by a battery, and equipped with safety protection and various auxiliary mechanisms (such as loading and assembly mechanisms).

[0003] For example, the patent document with the application number 202210099991.8 discloses an automatically guided vehicle chassis type charging mobile vehicle, including a vehicle body. A driving motor is installed inside the vehicle body, and a differential is sleeved outside the output end of the driving motor. Wheel sets are installed on both sides of the differential, and the ends of the wheel sets extend to the outside of the vehicle body. Multiple groups of storage batteries are installed inside the vehicle body, and two installation grooves are opened at the top of the vehicle body. In this invention, through the provided socket, when charging, the power transmission head is connected to the storage battery inside the vehicle body through a connecting wire, thereby charging the automatically guided vehicle. And when the power connection rod moves inside the socket, the air inside the socket will enter the air pipe, and the air flow will spray out from the air jet nozzle along the air pipe. And the air jet nozzle faces the power connection rod, so that the sprayed air flow cleans the power connection rod. The air pipe and the air jet nozzle can facilitate the entry of the power connection rod into the socket while cleaning the power connection rod, improving the use efficiency.

[0004] For similar charging mobile vehicles, during maintenance, the entire system may need to be disassembled, resulting in cumbersome and time-consuming operations, affecting work efficiency. And the charging equipment will cause wear of the connecting components during long-term use, resulting in loosening, leading to reduced charging efficiency, poor current transmission, and poor contact, thus affecting the charging effect and safety.

[0005] Therefore, in view of this, research and improvement are carried out on the existing structural deficiencies, and an automatically guided mobile charging chassis with a split design is proposed. Content of the Utility Model

[0006] The purpose of the utility model is to provide a problem that when maintaining an automatically guided mobile charging chassis with a split design, the entire system may need to be disassembled, resulting in cumbersome and time-consuming operations, affecting work efficiency. And the charging equipment will cause wear of the connecting components during long-term use, resulting in loosening, leading to reduced charging efficiency, poor current transmission, and poor contact, thus affecting the charging effect and safety.

[0007] To achieve the above object, the present utility model provides the following technical solutions: An automatically navigated mobile charging chassis with a split design, comprising a charging base, a mobile chassis, a limit lock hole, an infrared laser emitter, and an infrared laser receiver. A parking platform is provided inside the charging base. The mobile chassis is disposed on the upper end surface of the parking platform. A collision head is provided on the left end surface of the mobile chassis. The limit lock hole is provided on one side of the front and rear walls of the mobile chassis. A rechargeable battery is provided on the lower end surface on the right side of the mobile chassis. A ramp plate is provided on the left end surface of the parking platform. A charging socket is provided on the right side of the upper end surface of the parking platform. Electric telescopic rods are provided on one side of the front and rear walls of the charging base. Locking pins are provided at the output ends of the two groups of electric telescopic rods. The infrared laser emitter is provided on the side wall of the charging base. The infrared laser receiver is provided on the other side wall of the charging base.

[0008] Further, the rechargeable battery and the charging socket are engaged with each other, and the rechargeable battery and the charging socket form a charging structure.

[0009] Further, the output ends of the two groups of electric telescopic rods penetrate through the charging base and are connected to the locking pins. The positions of the two groups of limit lock holes and the two groups of locking pins correspond to each other horizontally.

[0010] Further, the apertures of the two groups of limit lock holes and the two groups of locking pins are equal in size, and the inner surface of each group of limit lock holes abuts against the outer surface of each group of locking pins.

[0011] Further, the infrared laser emitter and the infrared laser receiver form an infrared induction structure, and the positions of the infrared laser emitter and the infrared laser receiver correspond to each other horizontally.

[0012] Further, the inclination angle of the upper end surface of the ramp plate is 20 degrees, and the inclination angle of the lower end surface of the collision head is 45 degrees.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows: The split design enables the charging chassis and the charging seat to be separated, facilitating maintenance and replacement, and realizing automatic docking charging. By automatically locking the two sides of the chassis with locking pins, the connection between the charging chassis and the charging seat can be ensured to be more firm and stable, preventing movement or loosening during the charging process, reducing the need for human intervention, and improving the degree of automation. The specific content is as follows:

[0014] A charging base, a mobile chassis, a limit lock hole, an electric telescopic rod, a locking pin, an infrared laser emitter, and an infrared laser receiver are provided. By setting the mobile chassis and the charging base as a split type, the maintenance becomes simpler and more convenient, reducing the safety hazards during battery charging, facilitating its maintenance, and allowing the charging module and the battery module to be maintained separately. When the mobile chassis returns to the charging base, the control system plans the navigation route to fully embed the mobile chassis in the charging base. Through the engagement of the rechargeable battery and the charging socket, charging is carried out. When the mobile chassis moves to the charging socket, the infrared ray of the infrared laser emitter is blocked by the mobile chassis, thereby sending a signal to the control system. The control system controls the two groups of electric telescopic rods and the locking pin to pop out towards the mobile chassis and penetrate through its limit lock hole, thereby achieving automatic locking of the mobile chassis for charging. After charging is completed, the control system sends a signal to the electric telescopic rod to retract the locking pin at the output end, thereby releasing the chassis and enabling it to move freely. Such an automatic locking mechanism can ensure that the mobile chassis is firmly fixed on the charging base, preventing movement or shaking during charging, and thus avoiding accidental detachment from the charging socket.

[0020] The following further describes in detail the embodiments of the present invention with reference to the drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0021] As Figures 1 to 4As shown in the figure, an automatic navigation mobile charging chassis with a split design includes a charging base 1, a mobile chassis 2, a limit lock hole 4, an infrared laser emitter 11 and an infrared laser receiver 12. A parking platform 6 is provided in the inner cavity of the charging base 1. The charging base 1 is used to support and fix the mobile chassis 2, and at the same time provide a stable charging environment. The parking platform 6 is a platform for parking the mobile chassis 2, ensuring the stability between the charging base 1 and the mobile chassis 2, and at the same time providing a safe parking position. The mobile chassis 2 is arranged on the upper end surface of the parking platform 6. The mobile chassis 2 is the mobile platform of the robot. A collision avoidance head 3 is arranged on the left end surface of the mobile chassis 2. The inclination angle of the lower end surface of the collision avoidance head 3 is 45 degrees. The collision avoidance head 3 is used to avoid collisions and protect the mobile chassis 2 from being damaged during driving. The inclination angle of 45 degrees helps to reduce the impact force during collisions. A ramp plate 7 is arranged on the left end surface of the parking platform 6. The inclination angle of the upper end surface of the ramp plate 7 is 20 degrees. The ramp plate 7 helps the mobile chassis 2 to smoothly move up and down the ramp, ensuring the stability and smoothness of the mobile chassis 2 during movement;

[0022] A rechargeable battery 5 is arranged on the lower end surface on the right side of the mobile chassis 2. The rechargeable battery 5 is the power source of the mobile chassis 2, providing electrical energy for the mobile chassis 2, capable of storing electricity and performing cyclic charging. A charging socket 8 is arranged on the right side of the upper end surface of the parking platform 6, which is used to connect to the rechargeable battery 5 for charging. The rechargeable battery 5 and the charging socket 8 are meshed with each other. The rechargeable battery 5 and the charging socket 8 form a set of charging structure. The charging socket 8 is connected to an external power source through a wire. When meshed with the rechargeable battery 5, it will transmit electrical energy to the rechargeable battery 5 to charge it;

[0023] The limit lock hole 4 is arranged on one side of the front and rear walls of the mobile chassis 2. The limit lock hole 4 provides the fixing function for fixing the mobile chassis 2. Electric telescopic rods 9 are arranged on one side of the front and rear walls of the charging base 1. The output end of the electric telescopic rod 9 is controlled by a control system to expand and contract. The output ends of the two groups of electric telescopic rods 9 are both provided with locking pins 10. The output ends of the two groups of electric telescopic rods 9 penetrate through the charging base 1 and are connected to the locking pins 10. The aperture sizes of the two groups of limit lock holes 4 and the two groups of locking pins 10 are equal. The inner surface of each group of limit lock holes 4 is in contact with the outer surface of each group of locking pins 10. The two groups of locking pins 10 are respectively controlled by the expansion and contraction of the output ends of the two groups of electric telescopic rods 9, and penetrate into the limit lock holes 4 on both sides of the mobile chassis 2 to be fixed. The positions of the two groups of limit lock holes 4 and the two groups of locking pins 10 are horizontally corresponding to each other, and are horizontally corresponding to each other so as to correctly align with the limit lock holes 4 and the locking pins 10;

[0024] The infrared laser emitter 11 is provided on the side wall of the charging base 1. The infrared laser emitter 11 is used to emit infrared laser and is connected to the control system. The infrared laser receiver 12 is provided on the other side wall of the charging base 1. The infrared laser receiver 12 is used to receive the infrared laser emitted by the infrared laser emitter 11. The infrared laser emitter 11 and the infrared laser receiver 12 form an infrared induction structure. Through this infrared induction structure, it can be detected whether the mobile chassis 2 enters the charging base 1. The positions of the infrared laser emitter 11 and the infrared laser receiver 12 are horizontally corresponding to each other. When the mobile chassis 2 moves to the charging socket 8, the infrared ray of the infrared laser emitter 11 is blocked by the shell of the mobile chassis 2, thereby sensing the mobile chassis 2, and then sending a signal to the control system for processing.

[0025] In summary, as Figures 1 to 4 shown, for the automatically navigated mobile charging chassis with a split design, the navigation route is planned through the control system. The mobile chassis 2 can accurately return to the charging base 1 through the ramp plate 7 and be completely fitted in the charging base 1. When entering the parking platform 6 of the charging base 1, the mobile chassis 2 moves towards the charging socket 8, and the interface of the rechargeable battery 5 is engaged with the connector of the charging socket 8 through the planned navigation route, thereby charging. The infrared laser emitter 11 emits to the infrared laser receiver 12 in an induction state. When the mobile chassis 2 is charging, the infrared ray of the infrared laser emitter 11 is blocked by the mobile chassis 2, thereby sensing the mobile chassis 2 and sending a signal to the control system. The control system drives the locking pins 10 to extend towards the opposite side through the control of two groups of electric telescopic rods 9, thereby ejecting towards the mobile chassis 2 and penetrating into the limiting lock holes 4 at the same level, thereby realizing the automatic locking of the mobile chassis 2. When the charging is completed, the control system sends a signal to the electric telescopic rod 9 to contract, thereby releasing the chassis and enabling it to move freely. The anti-collision head 3 protects the front of the mobile chassis 2.
