Description

Technical Field

[0001] This utility model belongs to the field of cleaning robot charging technology, specifically relating to a cleaning robot charging base. Background Technology

[0002] A cleaning robot is a smart home appliance whose core function is to automatically clean the floor. Its purpose is to free people's hands and save time and energy. It uses the roller brush and side brush at the bottom to sweep loose garbage such as dust, hair, debris, and food scraps into the dust collection box, replacing the traditional step of manually sweeping the floor with a broom.

[0003] In existing technologies, when a cleaning robot detaches from its charging dock to perform autonomous cleaning operations, the charging socket is usually in a state of direct exposure. Moisture, corrosive components in the air, dust, and dirt that are commonly present in the environment will inevitably invade and adhere to the exposed charging electrodes and the charging socket area. This corrosion and contamination will not only significantly increase the resistance of the electrode contact surface, leading to decreased charging efficiency, poor contact, or even charging failure. Utility Model Content

[0004] The purpose of this invention is to provide a charging base for a cleaning robot that enables the cleaning robot to charge automatically, and the charging port is not exposed when the cleaning robot is detached from the charging base to perform autonomous cleaning operations.

[0005] The specific technical solution adopted by this utility model is as follows:

[0006] A charging base for a cleaning robot includes a charging frame that is adapted to fit and conform to the automatic cleaning robot. The automatic cleaning robot includes a robot body, two charging tentacles symmetrically arranged on the side of the robot body, and a positioning post at the middle of the bottom of the robot body. The charging frame has symmetrically opened charging slots, and charging components are symmetrically arranged in the charging slots. Each charging component is adapted to the charging tentacles. Each charging component includes a protective cover hinged to the end of the charging slot and an electrode plate movably disposed inside the charging slot. In the initial state, the protective cover closes the charging slot. When the automatic cleaning robot moves to a state of conformity with the charging frame, the protective cover opens the charging slot, the charging tentacles contact the electrode plates, and the electrode plates are energized.

[0007] Preferably, the bottom of the charging rack is provided with symmetrical guide strips, the guide strips are flared, the opening of the guide strips and their relative inner walls are adapted to the positioning posts, the curvature of the root of the guide strips is the same as the curvature of the side wall of the positioning posts, and the inner wall of the guide strips is provided with two soft rubber posts.

[0008] Preferably, a button switch is provided at the bottom center of the charging rack. The button switch is located between the roots of the two guide strips. The button switch is adapted to the positioning post. When the positioning post abuts against the button switch, the electrode plate is energized.

[0009] Preferably, a first spring is connected to the lower end of the protective cover, and the other end of the first spring is fixedly connected to the inner wall of the charging slot. The first spring is inclined.

[0010] Preferably, a second spring is connected to the bottom end of the electrode sheet, and the other end of the second spring is fixedly connected to the inner wall of the charging tank. The electrode sheet is made of an elastic conductive material.

[0025] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0026] A charging base for a cleaning robot includes a charging frame 2 that is adapted to fit and conform to an automatic cleaning robot 1. The automatic cleaning robot 1 includes a robot body 101, two charging tentacles 102 symmetrically arranged on the side of the robot body 101, and a positioning post 103 located at the middle of the bottom of the robot body 101. Charging slots are symmetrically opened on the charging frame 2, and charging components 21 are symmetrically arranged in the charging slots. Each charging component 21 is adapted to the charging tentacles 102. The charging component 21 includes a protective cover 211 hinged to the end of the charging slot and an electrode plate 212 movably arranged inside the charging slot. In the initial state, the protective cover 211 closes the charging slot. When the automatic cleaning robot 1 moves to a state of conformity with the charging frame 2, the protective cover 211 opens the charging slot, the charging tentacles 102 contact the electrode plate 212, and the electrode plate 212 is energized.

[0027] like Figures 1-8 As shown: The automatic cleaning robot 1 has the function of cleaning the ground. After the automatic cleaning robot 1 finishes its work, it automatically returns to the charging rack 2. The charging tentacles 102 set on the automatic cleaning robot 1 are inserted into the charging slot, and the charging tentacles 102 contact the electrode plates 212 to charge the automatic cleaning robot 1.

[0028] Preferably, the bottom of the charging rack 2 is symmetrically provided with guide strips 3, which are trumpet-shaped. The opening of the guide strip 3 and its relative inner wall are adapted to the positioning post 103. The curvature of the root of the guide strip 3 is the same as the curvature of the side wall of the positioning post 103. The inner wall of the guide strip 3 is provided with two soft rubber posts 301.

[0029] Preferably, a button switch 4 is provided at the bottom center of the charging rack 2. The button switch 4 is located between the roots of the two guide bars 3. The button switch 4 is compatible with the positioning post 103. When the positioning post 103 abuts against the button switch 4, the electrode plate 212 is energized.

[0030] like Figures 1-8 As shown: When the automatic cleaning robot 1 finishes its work and returns to the charging rack 2 to recharge, its positioning post 103 will move along the guide strip 3 on the charging rack 2. The positioning post 103 moves to the button switch 4 and touches it, triggering the electrode plate 212 on the charging rack 2 to be energized and start charging the automatic cleaning robot 1. At the same time, the positioning post 103 abuts against the soft rubber post 301 on the charging rack 2. The soft rubber post 301 provides flexible resistance to ensure that the robot stays stably on the charging rack 2 during the charging process and will not accidentally detach. When the automatic cleaning robot 1 needs to leave the charging rack 2 to start working, its own driving force is sufficient to overcome the flexible resistance of the soft rubber post 301, so that the positioning post 103 disengages from the abutting state with the soft rubber post 301, thereby achieving smooth detachment.

[0031] Preferably, the lower end of the protective cover 211 is connected to a first spring 5, the other end of the first spring 5 is fixedly connected to the inner wall of the charging slot, and the first spring 5 is set at an angle.

[0032] Preferably, the bottom end of the electrode sheet 212 is connected to a second spring 6, and the other end of the second spring 6 is fixedly connected to the inner wall of the charging tank. The electrode sheet 212 is made of an elastic conductive material.

[0033] Preferably, the protective cover 211 has a rubber ring 7 on its side wall, which abuts against the electrode plate 212 when the automatic cleaning robot 1 is charging.

[0034] like Figures 1-8 As shown: When the charging contact 102 enters the charging slot, it pushes the protective cover 211 to rotate into the charging slot. At this time, the first spring 5 deforms, and the charging contact 102 continues to move forward until it contacts the electrode plate 212. At this time, the second spring 6 allows the electrode plate 212 to move up and down in accordance with the position of the charging contact 102, ensuring a tight and reliable electrical connection. At the same time that the charging contact 102 abuts against the electrode plate 212, the rubber ring 7 also abuts against the side wall of the electrode plate 212, effectively preventing dust and other particles from falling into the charging slot during charging. When the automatic cleaning robot 1 detaches from the charging rack 2 to work, the first spring 5 rebounds, and after the protective cover 211 is reset, the rubber ring 7 set on its side wall fits tightly against the charging slot port, sealing the entire charging slot port and preventing dust from entering the slot.

[0035] Preferably, a baffle 8 is installed on the inner side wall of the charging slot. The baffle 8 is located on the side of the protective cover 211, and the baffle 8 is compatible with the side wall of the protective cover 211.

[0036] like Figures 1-8 As shown: When the automatic cleaning robot 1 detaches from the charging rack 2, the first spring 5 rebounds, driving the protective cover 211 to rotate towards the charging slot port. The baffle 8 at the charging slot port abuts against the protective cover 211, constraining its rotation angle and ensuring that the protective cover 211 covers the charging slot port, forming a closed protection.

[0037] The working principle of this utility model is as follows: When the automatic cleaning robot 1 finishes its work and returns to the charging rack 2 for charging, its positioning post 103 will move along the guide strip 3 on the charging rack 2. The positioning post 103 moves to the button switch 4 and touches it, triggering the electrode plate 212 on the charging rack 2 to be energized and start charging the automatic cleaning robot 1. At the same time, the positioning post 103 abuts against the soft rubber post 301 on the charging rack 2. The soft rubber post 301 provides flexible resistance to ensure that the robot stays stably on the charging rack 2 during the charging process and will not accidentally detach. When the automatic cleaning robot 1 needs to leave the charging rack 2 to start working, its own driving force is sufficient to overcome the flexible resistance of the soft rubber post 301, so that the positioning post 103 detaches from the abutting state with the soft rubber post 301, thereby achieving smooth detachment.

[0038] like Figures 1-8 As shown: When the charging contact 102 enters the charging slot, it pushes the protective cover 211 to rotate into the charging slot. At this time, the first spring 5 deforms, and the charging contact 102 continues to move forward until it contacts the electrode plate 212. At this time, the second spring 6 allows the electrode plate 212 to move up and down in accordance with the position of the charging contact 102, ensuring a tight and reliable electrical connection. At the same time that the charging contact 102 abuts against the electrode plate 212, the rubber ring 7 also abuts against the side wall of the electrode plate 212, effectively preventing dust and other particles from falling into the charging slot during charging. When the automatic cleaning robot 1 detaches from the charging rack 2 to work, the first spring 5 rebounds, and after the protective cover 211 is reset, the rubber ring 7 set on its side wall fits tightly against the charging slot port, sealing the entire charging slot port and preventing dust from entering the slot.

[0039] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
