Other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative efforts shall fall within the scope of protection of the present utility model. In addition, all the connection / connection relationships involved in the patent do not simply refer to the direct connection of components, but refer to the formation of a more optimal connection structure by adding or reducing connection accessories according to the specific implementation situation. The various technical features in the present utility model can be combined with each other without conflict.
[0031] Reference Figures 1 to 4 , a charging alignment structure for a floor sweeper, which is used to improve the accuracy and fault tolerance of the floor sweeper 4 when docking with the base station 5 for charging, thereby reducing the problem of charging failure caused by poor contact. The charging alignment structure of the floor sweeper is used in conjunction with the floor sweeper 4. The floor sweeper 4 is a prior art and includes conventional structures such as drive wheels and charging contacts. Therefore, the specific structure and working principle of the floor sweeper 4 will not be described in detail here. The charging alignment structure of the floor sweeper includes a base assembly and a connector assembly 3. Among them, the base assembly includes a base body 1 and a guiding member 2. The base body 1 is the base of the entire charging alignment structure of the floor sweeper, used to carry each component. The base body 1 has a laterally open receiving cavity 11. Usually, functional components for charging, adding cleaning liquid, and cleaning garbage are arranged in the receiving cavity 11 of the base station 5. During operation, the floor sweeper 4 enters the receiving cavity 11 to dock with these functional components for charging, cleaning and other operations; the guiding member 2 is used to guide at least part of the floor sweeper 4 into the receiving cavity 11 for charging, cleaning and other operations. The connector assembly 3 is arranged on the base body 1 and is located in the receiving cavity 11. When the floor sweeper 4 enters the receiving cavity 11 and the charging contacts of the floor sweeper 4 are in contact with and conduct with the connector assembly 3, the floor sweeper 4 can be charged. The connector assembly 3 includes a charging spring piece 31 and a spring piece bracket 32. A floating member is arranged on the spring piece bracket 32. The charging spring piece 31 is floatingly connected to the spring piece bracket 32 through the floating member. The spring piece bracket 32 is fixedly connected to the base body 1. The charging spring piece 31 is arranged on the spring piece bracket 32 through the floating member. When the floor sweeper 4 enters the receiving cavity 11 for charging, if the floor sweeper 4 fails to return to the charging position properly, that is, there is an alignment error between the charging contacts of the floor sweeper 4 and the charging spring piece 31, due to the floating member arranged between the charging spring piece 31 and the spring piece bracket 32, the charging spring piece 31 can be adjusted floatingly to ensure that the charging contacts of the floor sweeper 4 can accurately contact and conduct with the charging spring piece 31, thereby improving the accuracy and fault tolerance of the return charging.
[0032] Reference Figures 2 to 4, Further, the floating member is a floating spring 33. The shrapnel bracket 32 includes a bracket front end 321 and a bracket rear end 323. The bracket front end 321 and the bracket rear end 323 are sequentially connected to form the overall shrapnel bracket 32. Specifically, the charging shrapnel 31 is installed on the side of the bracket front end 321 facing away from the bracket rear end 323. One end of the floating spring 33 is connected to the bracket front end 321, and the other end is connected to the bracket rear end 323. When the sweeping robot 4 is in the process of returning to charge and aligning, the floating spring 33 is subjected to the force of the sweeping robot 4 and undergoes elastic contraction, so that the charging shrapnel 31 is aligned and contacted with the charging contact of the sweeping robot 4 for the charging operation. The surface of the charging shrapnel 31 is provided with charging bumps, which are in contact with and conduct electricity with the charging contacts of the sweeping robot 4 during charging. In this embodiment, a pin 311 is fixedly connected to the charging shrapnel 31, and a hole groove is provided on the pin 311. A buckle position matching the hole groove is provided on the inner wall of the bracket front end 321. During installation, the pin 311 of the charging shrapnel 31 is inserted into the bracket front end 321, and at this time, the buckle position is snapped into the hole groove to realize the connection and fixation of the charging shrapnel 31 to the bracket front end 321.
[0033] Furthermore, the base body 1 includes an infrared lens 12 for installing the shrapnel bracket 32. An installation hole 121 for installing the shrapnel bracket 32 is provided on the infrared lens 12. The installation hole 121 communicates with the receiving cavity 11. The shrapnel bracket 32 is installed in the installation hole 121. The bracket rear end 323 is fixedly installed on the infrared lens 12 and is located on the side of the installation hole 121 facing away from the receiving cavity 11. The bracket front end 321 is movable in the installation hole 121, and the bracket front end 321 can extend into the receiving cavity 11 from the installation hole 121. The floating spring 33 is arranged between the bracket front end 321 and the bracket rear end 323. A guiding column 322 is fixedly connected to the side of the bracket front end 321 facing the bracket rear end 323. The floating spring 33 is sleeved on the guiding column 322. One end of the floating spring 33 is fixedly connected to the bracket front end 321, and the other end is fixedly connected to the bracket rear end 323. A relief hole 3231 is provided on the bracket rear end 323. The shape and size of the relief hole 3231 are adapted to the guiding column 322. When the charging shrapnel 31 is squeezed, the floating spring 33 is elastically compressed, and at this time, the guiding column 322 slides in the relief hole 3231. The bracket front end 321 and the bracket rear end 323 are floatingly connected by the floating spring 33. When the sweeping robot 4 is in the process of returning to charge and aligning, pressure is applied to the charging shrapnel 31, and the floating spring 33 elastically contracts, so that the charging shrapnel 31 has a floating space in the axial direction of the guiding column 322, ensuring the precise alignment between the charging shrapnel 31 and the charging contacts of the sweeping robot 4; and under the elastic action of the floating spring 33, the charging shrapnel 31 can also be pressed against the charging contacts of the sweeping robot 4, ensuring full contact between the charging shrapnel 31 and the charging contacts of the sweeping robot 4, and effectively reducing the possibility of charging failure of the sweeping robot 4 due to poor contact.
[0034] A bracket limit block is fixedly connected to one side of the bracket front end 321 close to the bracket tail end 323. When the floating spring 33 is elastically released, the bracket limit block abuts against the side of the infrared lens 12 facing away from the accommodating cavity 11. The bracket limit block restricts the movement of the bracket front end 321 to reduce the possibility of the bracket front end 321 being detached from the infrared lens 12.
[0035] In this embodiment, two guide posts 322 are provided on the front end 321 of the bracket, and floating springs 33 are sleeved on the two guide posts 322. Accordingly, the rear end 323 of the bracket is provided with a clearance hole 3231 corresponding to the two guide posts 322. The front end 321 of the bracket has a certain curvature, and accordingly, the charging spring 31 is also set with a certain curvature. The curvature of the front end 321 of the bracket and the charging spring 31 is matched with the curvature of the outer shape of the sweeper 4. When the sweeper 4 contacts the connector assembly 3 for charging, the curved outer shape can make the charging spring 31 fit the sweeper 4 more closely. Two floating springs 33 are provided, and the two floating springs 33 can be adjusted independently, thereby changing the inclination angle of the charging spring 31, further ensuring that the charging spring 31 contacts the charging contact on the sweeper 4, and improving the alignment fault tolerance rate.
[0036] Reference Figure 1 and Figure 2 The guide member 2 is connected to the base body 1. Since the receiving chamber 11 is usually set at a certain height from the ground, the guide member 2 is set on the base body 1. The sweeper 4 climbs along the guide member 2 to enter the receiving chamber 11. Usually, the sweeper 4 extends into the receiving chamber 11 in an inclined posture. The guide member 2 has a climbing surface 21 connected to the receiving chamber 11. The climbing surface 21 is provided with a guide groove 22. The guide groove 22 is used for the driving wheel of the sweeper 4 to pass through, and guides the sweeper 4 to move along the guide groove 22 to at least partially enter the receiving chamber 11.
[0037] Furthermore, there are two guide grooves 22, which are symmetrically arranged on the climbing surface 21 and are in an "eight"-shaped structure. The spacing between the two guide grooves 22 is adapted to the spacing between the driving wheels of the sweeping machine 4. And the width of the guide groove 22 is set to gradually narrow along the direction in which the sweeping machine 4 crawls into the receiving chamber 11. The guide groove 22 is set to limit the climbing direction of the sweeping machine 4 to ensure that the sweeping machine 4 climbs at the correct angle, which is beneficial to improving the positioning accuracy of the sweeping machine 4. The width of the guide groove 22 is set to gradually narrow along the crawling direction of the sweeping machine 4, further increasing the guidance of the sweeping machine 4 into the receiving chamber 11.
[0038] Furthermore, a positioning groove 23 is formed on the climbing surface 21, and the positioning groove 23 is formed on the side of the guiding groove 22 close to the accommodating cavity 11. The opening shape of the positioning groove 23 is adapted to the shape of the driving wheel of the sweeper 4. The positioning groove 23 further positions the sweeper 4 for recharging alignment, so as to further ensure the accurate positioning of the sweeper 4 and the accuracy of alignment. Moreover, through the arrangement of the positioning groove 23, with a simple structure, the sweeper 4 can be parked in an inclined posture in the accommodating cavity 11 for charging operation. Two balance clamping points 25 are fixedly arranged on the climbing surface 21, and the two guiding grooves 22 are located between the two balance clamping points 25. The balance clamping points 25 on both sides support the sweeper 4. When the sweeper 4 is parked in the positioning groove 23 for charging, it is in an inclined posture. The balance clamping points 25 are provided to effectively support the sweeper 4, effectively reducing the possibility that the sweeper 4 tilts or shakes during charging, resulting in inaccurate alignment and poor contact between the charging elastic sheet 31 and the charging contact of the sweeper 4, which affects the normal charging process.
[0039] In one embodiment, anti-slip rib strips 24 are arranged at intervals on the surfaces of the guiding groove 22 and the positioning groove 23 in the advancing direction of the sweeper 4. The free ends of the anti-slip rib strips 24 are in the shape of a wedge tip inclined towards the accommodating cavity 11. The arrangement of the anti-slip rib strips 24 can improve the grip ability of the driving wheel of the sweeper 4, making its climbing process smoother. It can be understood that in other embodiments, the friction between the sweeper 4 and the guiding groove 22 and the positioning groove 23 can also be increased by other forms such as setting frosted surfaces, patterns or anti-slip layers to ensure the smooth climbing of the driving wheel.
[0040] Furthermore, guiding surfaces 221 are arranged on the climbing surface 21 on the sides where the two guiding grooves 22 are away from each other. The guiding surfaces 221 are inclined to the guiding grooves 22, and the inclination degree of the guiding surfaces 221 increases along the climbing direction of the guiding grooves 22. The guiding surfaces 221 are provided to guide the driving wheels of the sweeper 4, so that the driving wheels of the sweeper 4 can accurately enter the guiding grooves 22. Positioning inclined surfaces 231 are also formed on the climbing surface 21 on the sides where the positioning grooves 23 are away from each other. The positioning inclined surfaces 231 guide the driving wheels of the sweeper 4, so that the sweeper 4 can accurately snap into the positioning grooves 23 when climbing along the guiding grooves 22.
[0041] In one embodiment, a positioning boss 26 that matches the bottom bone position of the sweeper 4 is fixedly connected to the bottom of the base body 1. When the drive wheels of the sweeper 4 are inserted into the positioning grooves 23, the positioning boss 26 abuts against the bottom bone position of the sweeper 4 to mechanically position the sweeper 4, further ensuring the accuracy of the charging alignment of the sweeper 4. The top of the positioning boss 26 is in an arc chamfer structure. Setting the top in an arc chamfer structure is beneficial to reducing the possibility of the positioning boss 26 scratching the sweeper 4 when the sweeper 4 abuts against the positioning boss 26.
[0042] Based on the above charging alignment structure of the sweeper, the present utility model further provides:
[0043] A sweeper base station, including the sweeper charging alignment structure with the above-mentioned structure. The base station 5 can provide stable and reliable charging services for the sweeper 4, improving the charging alignment accuracy and user experience of the sweeper 4.
