Some embodiments of the present invention are described in detail below with reference to the accompanying drawings. The following embodiments and features of the embodiments may be combined with each other without conflict.
First embodiment:
referring to fig. 1 and fig. 2 in combination, fig. 1 is a schematic structural diagram of a laser measuring device 100 according to a preferred embodiment of the present invention, wherein the laser measuring device is operated in a first measuring mode, and fig. 2 is an exploded schematic diagram of fig. 1. The laser measurement device 100 provided by the present invention may include a first laser rangefinder 110, a second laser rangefinder 120, and a conductive structure. It will be appreciated that in the first embodiment, the conductive structure is a first conductive structure 130 (shown with reference to fig. 4).
In this embodiment, the first laser rangefinder 110 is electrically connected to the second laser rangefinder 120 through the first conductive structure 130, so that data interaction can be performed between the first laser rangefinder 110 and the second laser rangefinder 120, and further, after the first laser rangefinder 110 and the second laser rangefinder 120 are combined, the laser emission power is increased, and the range is further increased. In addition, the first laser rangefinder 110 is connected with the second laser rangefinder 120 through a detachable connection mode, so that the laser measuring device 100 can be conveniently disassembled and assembled, and meanwhile, the laser measuring device 100 can be conveniently carried. For example, when the space for carrying the laser measuring device 100 is insufficient to accommodate two laser rangefinders, the first laser rangefinder 110 and the second laser rangefinder 120 (which may be simply referred to as two rangefinders) may be split for carrying.
The two distance meters can be the same kind of laser distance meters or different kinds of laser distance meters. For example, the laser rangefinder may be, but is not limited to, a pulsed (or echo) laser rangefinder, a phased laser rangefinder, etc., and is not specifically limited herein. Preferably, the first laser rangefinder 110 and the second laser rangefinder 120 are the same type and model of laser rangefinder.
Referring to fig. 3, a second schematic structure of the laser measuring device 100 according to the preferred embodiment of the invention is shown in the first measuring mode. In this embodiment, the first laser rangefinder 110 may include a first laser emitting end 111 and the second laser rangefinder 120 may include a second laser emitting end 121. The first laser emission end 111 and the second laser emission end 121 are arranged side by side, and are positioned on the same side, and emit two parallel laser beams along the same direction. The distance measurement is carried out through the cooperation of the two distance meters, so that the measurement accuracy and the measurement range can be improved.
Specifically, for example, the distance value(s) measured by the laser measuring device 100 is an average value of the measured distance value (a) of the first laser distance meter 110 and the measured distance value (b) of the second laser distance meter 120, so as to improve the measurement accuracy.
Referring to fig. 2, 3 and 4 in combination, fig. 4 is a cross-sectional view of section A-A in fig. 3. In the present embodiment, the laser measuring device 100 may further include an angle sensor 140 and a first connection structure 150. The angle sensor 140 is accommodated in the first laser range finder 110 and is rotatably connected with the second laser range finder 120. The first connection structure 150 is used to detachably connect the first laser rangefinder 110 with the second laser rangefinder 120. An angle sensor 140 may be provided for measuring the angle between the first laser rangefinder 110 and the second laser rangefinder 120. Which typically corresponds to the angle of the object to be measured (e.g., the angle between the two objects and the measurement point). That is, when the laser measuring device 100 operates in the first measuring mode as shown in fig. 1, the first laser rangefinder 110 and the second laser rangefinder 120 can rotate through the angle sensor 140, so that a certain included angle is formed between the two. That is, the laser measuring device 100 can be used for measuring angles as well as distances.
It should be noted that, the first laser rangefinder 110 and the second laser rangefinder 120 may rotate continuously. It is understood that the angle of rotation of the first laser rangefinder 110 relative to the second laser rangefinder 120 ranges from 0 ° to 360 °, which may include 0 ° and 360 °.
Further, the angle sensor 140 may include a sensor body 141 and a shaft body 142 rotatably connected to the sensor body 141. The sensor body 141 is fixedly disposed on the first laser range finder 110. The first laser rangefinder 110 and the second laser rangefinder 120 are rotatably connected through the sensor body 141, the shaft body 142 and the first connection structure 150, so that angle measurement can be realized.
Further, please refer to fig. 4 and fig. 5 in combination, wherein fig. 5 is a partially enlarged schematic view of the I portion in fig. 4. At least two first conductive structures 130 are provided to electrically connect the two rangefinders. Optionally, the laser measurement device 100 comprises two first conductive structures 130. The first conductive structure 130 may include a first conductive contact 131 disposed on the shaft 142 and a second conductive contact 132 disposed on the second laser rangefinder 120. The first conductive contact 131 and the second conductive contact 132 are sheet-like structures having a conductive function. For example, the first and second conductive contacts 131 and 132 may be, but not limited to, a copper sheet, an aluminum sheet, or the like. The shape, structure and size of the two may be the same or different, so long as the first conductive contact 131 can contact with the second conductive contact 132 and can be electrically connected, which is not particularly limited herein.
In the present embodiment, the laser measuring device 100 may further include a cover 143 for covering the angle sensor 140. The cover 143 is disposed at a position of the first laser rangefinder 110 corresponding to the angle sensor 140, and the cover 143 is provided with a through hole for exposing the shaft 142, so that the shaft 142 and the second laser rangefinder 120 are connected through the first connection structure 150, and entry of impurities such as dust can be avoided.
It should be noted that, measurement circuits (not shown) are provided in both rangefinders. The first conductive contact 131 is electrically connected to measurement circuitry in the first laser rangefinder 110 and the second conductive contact 132 is electrically connected to measurement circuitry in the second laser rangefinder 120. In this way, when the two first conductive contacts 131 and the two second conductive contacts 132 are correspondingly contacted, the electrical connection between the first laser rangefinder 110 and the second laser rangefinder 120 is realized.
In other embodiments, the first conductive contact 131 and the second conductive contact 132 may be replaced by other structures. For example, two jacks are disposed on the shaft 142, two pins matched with the two jacks are disposed on the second laser rangefinder 120, and the electrical connection of the two rangefinders is realized through the two jacks and the two pins.
When the laser measuring device 100 is operated in the first measuring mode, the second laser rangefinder 120 is connected to the shaft 142 via the first connection structure 150, so that the two rangefinders are rotatably connected. The first conductive contact 131 is electrically contacted with the second conductive contact 132, so that the first conductive contact and the second conductive contact are electrically connected, and further data communication and interaction are realized.
Referring to fig. 4 again, in the present embodiment, the first connecting structure 150 may include a first magnetic member 151 and a second magnetic member 152. The first magnetic element 151 is accommodated in the first laser range finder 110, and the second magnetic element 152 is accommodated in the angle sensor 140 and is disposed opposite to the first magnetic element 151. The first laser range finder 110 may be provided with a groove for fixing the first magnetic member 151, and the angle sensor 140 may be provided with a groove for fixing the second magnetic member 152. The first magnetic member 151 and the second magnetic member 152 (which may be simply referred to as two magnetic members) are respectively fastened by disposing the first magnetic member 151 and the second magnetic member 152 in the corresponding fastening grooves.
It should be noted that, when the laser measuring device 100 is operated in the first measuring mode, two ends of the first magnetic member 151 and the second magnetic member 152, which are close to each other, are opposite in magnetic pole. That is, the first magnetic member 151 and the second magnetic member 152 are attracted to each other to mechanically connect the first laser rangefinder 110 and the angle sensor 140, thereby achieving the detachable connection of the first laser rangefinder 110 and the second laser rangefinder 120.
Of course, in other real-time modes, the first magnetic member 151 and the second magnetic member 152 may be fixed to the corresponding laser rangefinder by embodiments different from those described above. For example, the first magnetic member 151 and the second magnetic member 152 may be adhered and fixed on the corresponding laser rangefinder by glue.
The shape, structure and size of the two magnetic pieces can be the same or different. For example, both may be of a cylindrical structure or a sheet-like structure of the same size, and the like, and are not particularly limited herein. The materials constituting the magnetic material may be the same magnetic material or different magnetic materials. For example, the magnetic material may be, but is not limited to, a magnet, a magnetic steel, a magnet, or the like. Preferably, the magnetic material is a permanent magnetic material, such as ferrite.
Referring to fig. 5 again, the second laser rangefinder 120 is provided with at least one limiting member (which may be referred to as a first limiting member 162 in this embodiment), and the shaft 142 may be provided with at least one limiting hole (which may be referred to as a first limiting hole 161 in this embodiment) matching the first limiting member 162. The first limiting piece 162 is protruding on the surface of the second laser range finder 120 opposite to the first laser range finder 110, and can be accommodated in the first limiting hole 161. The second laser range finder 120 and the shaft body 142 realize rapid alignment between the first laser range finder 110 and the second laser range finder 120 through the first limiting piece 162 and the first limiting hole 161 so as to avoid the influence of the relative movement of the second laser range finder 120 and the shaft body 142 on the accuracy of the measured angle. In addition, in the process of installing the laser measuring device 100, the first limiting piece 162 and the first limiting hole 161 can accurately position the two distance measuring devices, so that the installation operation is convenient. The number of the first limiting members 162 and the first limiting holes 161 may be set according to practical situations, and is not particularly limited herein.
Further, the first limiting member 162 may have a sheet-like structure or a columnar structure, which is not particularly limited herein.
It should be noted that, in other embodiments, the sensor body 141 may be fixedly disposed on the second laser rangefinder 120. When the laser measuring device 100 operates in the first measuring mode, the first laser rangefinder 110 is connected to the shaft 142 through the first connection structure 150 to achieve mechanical connection of the two rangefinders, and then electrical connection of the two rangefinders is achieved through the first conductive structure 130.
In this embodiment, the first laser rangefinder 110 and/or the second laser rangefinder 120 may be provided with a display module 190 for displaying measurement data and a key set. The measurement data includes at least one of angle data and distance data. For example, a display module 190 may be provided on both rangefinders to display measurement data separately.
Specifically, the display module 190 may be, but is not limited to, a liquid crystal display, a nixie tube, etc., which is not particularly limited herein.
In this embodiment, the first laser rangefinder 110 and/or the second laser rangefinder 120 may be provided with a power module to continuously provide power for the measurement of the laser measurement device 100. The power module may be a dry battery, a lithium ion battery, or the like, and is not particularly limited herein.
Second embodiment:
referring to fig. 6 and 7 in combination, fig. 6 is a third schematic structural diagram of the laser measuring device 100 according to the preferred embodiment of the present invention, in which the laser measuring device is operated in the first measuring mode, and fig. 7 is a cross-sectional view of the section B-B in fig. 6. The laser measuring device 100 according to the second embodiment has substantially the same shape structure, operation principle and technical effects as those of the first embodiment, except that the first connection structure 150 according to the second embodiment is different from the connection structure according to the first embodiment. The first connecting structure 150 in the second embodiment is a mortise and tenon structure, and the second laser rangefinder 120 is connected with the shaft body 142 by means of mutual fastening.
Specifically, the first connection structure 150 in the second embodiment may include a fixing groove (may be referred to as a first fixing groove 153 in the second embodiment) provided on the second laser rangefinder 120, and a fixing piece (may be referred to as a first fixing piece 154 in the second embodiment) provided on the shaft body 142 to be mated with the first fixing groove 153. The first fixing groove 153 and the first fixing piece 154 are matched with each other to form a mortise-tenon structure, and the mortise-tenon structure and the first fixing piece are mutually buckled to enable the second laser range finder 120 to be connected with the shaft body 142, so that the connection of the first laser range finder 110 and the second laser range finder 120 is achieved.
Referring to fig. 7, 8 and 10 in combination, fig. 8 is a partially enlarged schematic view of a portion II in fig. 7, and fig. 10 is an exploded schematic view of fig. 6. In the present embodiment, the first conductive contact 131 may be disposed on the first fixing member 154, and the second conductive contact 132 may be disposed at a position corresponding to the first fixing groove 153. When the laser measuring device 100 needs to be assembled to work in the first measuring mode, the first fixing piece 154 on the first laser range finder 110 can be slid into the first fixing groove 153, so that the mechanical connection of the two range finders is realized; after the first fixing piece 154 slides into the first fixing groove 153, the two first conductive contact pieces 131 are contacted with the corresponding second conductive contact pieces 132, so that the first laser range finder 110 and the second laser range finder 120 are electrically connected.
Referring to fig. 10, 11 and 12 in combination, fig. 11 is an exploded view of the angle sensor 140 shown in fig. 10 at one viewing angle, and fig. 12 is an exploded view of the angle sensor 140 shown in fig. 10 at another viewing angle. In this embodiment, the shape and the number of the conductive structures may be the same as or similar to those provided in the first embodiment, and will not be described here. In addition, the angle sensor 140 in the second embodiment may further include a ball plunger 144.
The sensor body 141 is rotatably connected with the shaft body 142, the ball plunger 144 is arranged on the shaft body 142, and a positioning hole matched with the ball plunger 144 is arranged at a position of the second laser range finder 120 corresponding to the angle sensor 140. Through the positioning hole and the ball plunger 144, the two distance meters can be accurately positioned in the installation process, and the installation operation is convenient.
The mutual rotation angle of the two rangefinders in this embodiment is the same as that of the first embodiment, and will not be described here again. When the first laser rangefinder 110 rotates relative to the second laser rangefinder 120, it can be used to measure angles or distances between any two points. When the first laser rangefinder 110 and the second laser rangefinder 120 overlap, that is, the first laser transmitting end 111 and the second laser transmitting end 121 are located on the same side, and the lasers transmitted along the same direction are parallel, the laser measuring device 100 can be used for measuring the distance.
Third embodiment:
referring to fig. 13 and 14 in combination, fig. 13 is a schematic structural diagram of a laser measuring device 100 according to a preferred embodiment of the present invention operating in a second measuring mode, and fig. 14 is an exploded schematic diagram of fig. 13. In this embodiment, the laser measuring device 100 may include a connection structure, a conductive structure, and a first laser rangefinder 110 and a second laser rangefinder 120 as in the first embodiment. The connection structure is a second connection structure 170 in the third embodiment, and is used for detachably connecting an end of the first laser rangefinder 110 away from the first laser emitting end 111 with an end of the second laser rangefinder 120 away from the second laser emitting end 121. The conductive structure is a second conductive structure 180 in the third embodiment, and is used to electrically connect the two rangefinders when the laser measuring device 100 is operating in the second measurement mode.
Specifically, the second conductive structure 180 is configured to electrically connect the first laser rangefinder 110 and the second laser rangefinder 120 when the end of the first laser rangefinder 110 away from the first laser transmitting end 111 is detachably connected with the end of the second laser rangefinder 120 away from the second laser transmitting end 121.
For example, when the laser measuring device 100 operates in the second measuring mode, the first laser rangefinder 110 and the second laser rangefinder 120 are connected through the second connection structure 170, so that the first laser rangefinder 110 and the second laser rangefinder 120 are coplanar and arranged in line, and are electrically connected through the second conductive structure 180, so that the laser emitted by the first laser emitting end 111 and the laser emitted by the second laser emitting end 121 emit laser along two opposite directions, and the two laser beams are parallel or on the same line.
It will be appreciated that the laser measurement device 100 may be used to measure distance when operating in the second measurement mode. The measured distance value(s) is the sum of the measured distance value (a) of the first laser distance meter 110, the measured distance value (b) of the second laser distance meter 120 and the length (c) of the measuring distance meter, so that the range (or the maximum range) of the measured distance is increased.
In addition, the laser measuring device 100 is also advantageous for measuring the distance between two objects in an enclosed space. For example, if it is desired to measure the distance between two parallel walls in the room, the laser measuring device 100 is only required to be assembled into a structure of the second measuring mode, that is, the two rangefinders are connected by the second connecting structure 170 and electrically connected by the second conductive structure 180. The operator does not need to make the laser measuring device 100 abut against one of the walls, and can measure the distance between two parallel walls only by making the laser measuring device 100 be positioned at any position between the two walls and making the two emitted lasers respectively perpendicular to the walls of the two walls.
