Detachable handheld laser scanner system supporting multiple plug-in combinations

A detachable handheld laser scanner system supporting multiple plug-in combinations, comprising:

• a main unit;
• an extension member;
• and
• a plurality of external components;
• wherein a housing of the main unit is provided with the extension member;
• the extension member comprises an engagement cavity, a data interface and a clamping part;
• the engagement cavity is recessed on a side of the housing along a first direction;
• the data interface is provided on an inner wall of the engagement cavity;
• and the clamping part is movably provided in the housing;
• the engagement cavity has a first side wall and a second side wall opposite to each other in a second direction, wherein the second direction intersects the first direction;
• the clamping part is provided with a limiting portion configured to act on the plurality of external components;
• the plurality of external components comprise a lidar module, a structured-light scanning module, an image acquisition module or a combination thereof;
• each of the plurality of external components is provided with an engagement portion configured to engage with the engagement cavity;
• a surface of the engagement portion is provided with a data connector configured to mate with the data interface;
• in response to a case that each of the plurality of external components is inserted into the engagement cavity along the first direction, the engagement portion is engaged with the engagement cavity in the first direction, the clamping part is configured to be operated to cause the limiting portion to abut against the engagement portion together with the first side wall in the second direction to achieve a locked state between the main unit and the plurality of external components, and the data connector is configured to mate with the data interface to establish data communication;
• in response to a case that the clamping part is operated to allow a distance between the limiting portion and the first side wall in the second direction to be not smaller than a distance between the first side wall and the second side wall, each of the plurality of external components is configured to disengage from the engagement cavity along the first direction to achieve an unlocked state;
• the main unit is configured to be selectively connected to corresponding one or more of the plurality of external components according to different application scenarios through a detachable connection between the extension member and the corresponding one or more of the plurality of external components, so as to realize a point-cloud accuracy enhancement function, a micro-target modeling function, an image-texture fusion function or a combination thereof;
• an outer contour of the engagement portion is configured to match a contour of the inner wall of the engagement cavity;
• at least two side walls of the engagement portion are each provided with a guide rib extending along the first direction;
• and the inner wall of the engagement cavity is provided with a guide groove configured to slidably receive the guide rib;
• the data connector is configured as a contact-type connector;
• the data interface is configured as an elastic contact piece set adapted to the contact-type connector;
• the elastic contact piece set is electrically connected to a main control chip of the main unit through a flexible printed circuit board;
• the clamping part comprises a push rod slidably provided in the housing;
• a first end of the push rod is configured to extend outside the housing to form an operating portion, and a second end of the push rod is oriented toward the engagement cavity and is provided with the limiting portion;
• the limiting portion is configured as a wedge-shaped protrusion inclined toward the first side wall;
• the engagement portion is provided with a limiting slot at a position corresponding to the wedge-shaped protrusion, and the limiting slot is configured to engage with the wedge-shaped protrusion;
• and
• in response to a case that the operating portion is pushed along the second direction, the wedge-shaped protrusion is configured to be inserted into the limiting slot and to abut against the first side wall to achieve the locked state.
