Description

Technical Field

[0001] This application relates to the field of ranging equipment technology, and in particular to a handheld ranging device. Background Technology

[0002] In the design of handheld imaging devices, the definition and settings of the ranging function are generally divided into two types: built-in and external. Among them, the external ranging design can be further divided into quick-release ranging and non-quick-release ranging.

[0003] Existing quick-release ranging technologies are limited by the installation method and the form and position tolerances and dimensional tolerance sets of machining. The quick-release ranging module is relatively far from the main unit, and the angle between the main unit's optical axis and the ranging optical axis may increase, leading to a decrease in ranging accuracy. Non-quick-release ranging modules are more cumbersome to install, limiting their outdoor operation. Therefore, it is necessary for those skilled in the art to provide a handheld ranging device that is easy to install and disassemble and has high ranging accuracy. Summary of the Invention

[0004] The purpose of this application is to provide a handheld ranging device that is easy to install and disassemble, and has high ranging accuracy.

[0005] To achieve the above objectives, this application provides a handheld ranging device, comprising:

[0006] body;

[0007] The ranging adapter is fixedly installed on the device body;

[0008] The ranging module is detachably mounted to the main body via a ranging adapter and powered on after docking with the main body. The ranging module includes:

[0009] Main shell;

[0010] The rotating wheel is rotatably connected to the main housing. The rotating wheel is provided with a gradually thickening claw, which is used to abut against the ranging adapter along the thickness direction when the rotating wheel rotates relative to the main housing, so that the main housing and the rotating wheel move in the direction closer to the fuselage, so as to realize the connection between the ranging module and the fuselage.

[0011] The fixing block, connected to the rotating wheel, is used to lock the main housing when the rotating wheel reaches a preset position.

[0012] To fix the rotating wheel.

[0013] In some embodiments, the ranging adapter includes a base plate and a boss disposed on the base plate, with a preset gap between the boss and the base plate for the protruding claw to extend into.

[0014] In some embodiments, the protruding claw is provided with a protruding edge that protrudes towards the inside of the protruding claw, and a mating surface is provided between the boss and the base plate to contact and abut against the protruding edge to prevent the rotation of the wheel.

[0015] In some embodiments, the main shell is provided with two first limiting blocks, and the ranging adapter is provided with a second limiting block and two limiting spaces located on both sides of the second limiting block. The second limiting block is used to fit between the two first limiting blocks, and the two limiting spaces are used to fit with the two first limiting blocks respectively to fix the main shell.

[0016] In some embodiments, the ranging module further includes:

[0017] The pressure roller is movably installed inside the rotating wheel and is used to abut against the ranging adapter when the rotating wheel rotates;

[0018] The first elastic element abuts between the pressure roller and the main housing, and is used to provide elastic force to the pressure roller, so that the pressure roller tends to move closer to the fuselage.

[0019] In some embodiments, the pressure roller is provided with a lug and a through hole, and the ranging module further includes a connecting post that passes through the through hole and is connected to the main housing.

[0020] In some embodiments, the main housing is provided with a slide rail, and the rotating wheel is provided with a plurality of protrusions distributed in a circumferential direction. Each protrusion is screwed into the slide rail and can slide along the slide rail.

[0021] The main shell is also provided with a limiting protrusion with a notch. A tail baffle is detachably connected to the rotating wheel. The tail baffle is used to rotate within the notch to drive the rotating wheel to rotate, while limiting the rotation position of the rotating wheel and preventing the protrusion from dislodging from the slide.

[0022] In some embodiments, the main housing is provided with a locking block, the fixing block is provided with a locking slot and a limiting hole, the tail baffle is provided with a guide post, the guide post is provided in the limiting hole, the fixing block moves within the limited range of the limiting hole, and when the rotating wheel rotates to a preset position, it pushes the fixing block so that the locking slot locks the locking block.

[0023] In some embodiments, the fixing block is further provided with a locking groove, which is larger at both ends and smaller in the middle. The tail baffle is provided with a receiving groove, in which a ball and a second elastic member are provided. The ball is used to slide along the locking groove, and the second elastic member abuts between the ball and the tail baffle. The second elastic member is used to provide elastic force to the ball, so that the ball has a tendency to detach from the tail baffle.

[0024] In some embodiments, the ranging module further includes a male connector and a female connector on the body. The female connector passes through the ranging adapter, and the ranging module is powered on after the female connector and the male connector are connected.

[0025] Compared to the aforementioned background technology, the handheld ranging device provided in this application includes a body, a ranging adapter, and a ranging module. The ranging adapter is fixedly mounted on the body, and the ranging module is detachably mounted on the body via the ranging adapter. The ranging module is electrically connected to the body (power is applied after the ranging module is connected to the body). Further, the ranging module includes a main shell, a rotating wheel, and a fixing block. The rotating wheel is rotatably connected to the main shell and has gradually varying thickness protrusions. These protrusions abut against the ranging adapter along the thickness direction when the rotating wheel rotates relative to the main shell, causing the main shell and the rotating wheel to move towards the body during rotation, thus connecting the ranging module to the body. The fixing block connects to the rotating wheel and locks the main shell when the rotating wheel reaches a preset position, thereby fixing the rotating wheel. During installation, first, rotate the ranging module's rotating wheel to a position where it does not interfere with the ranging adapter, and then assemble the ranging module onto the body. Next, rotate the rotating wheel so that the claws on the wheel abut against the ranging adapter, causing the main housing and the rotating wheel to move closer to the body as the wheel rotates, thus connecting the ranging module to the body. When the rotating wheel reaches a preset position, push the fixing block to lock it into place, thereby securing the rotating wheel. This completely fixes the ranging module to the body. Furthermore, disassembling the ranging module can be accomplished by reversing the above steps. Compared to traditional handheld ranging devices that are inconvenient to assemble and disassemble with the main unit and have low ranging accuracy, the handheld ranging device provided in this application embodiment allows for convenient and quick installation of the ranging module onto the main unit. The ranging module is positioned by the rotation of the rotating wheel and the movement of the fixing block. The ranging module is easy and quick to install and disassemble, and the positioning accuracy after assembly is high. The assembled ranging module is powered by the main unit. At the same time, the above installation method can avoid the possibility of changes in the angle between the main unit's optical axis and the ranging optical axis, thereby ensuring the parallelism and consistency of the main unit's optical axis and the ranging optical axis, which is beneficial to ensuring ranging accuracy.

[0051] The handheld ranging device provided in this application includes a body 10, a ranging adapter 20, and a ranging module 30. The ranging adapter 20 is fixedly installed on the body 10, and the ranging module 30 is detachably installed on the body 10 through the ranging adapter 20. The ranging module 30 is electrically connected to the body 10.

[0052] It should be noted that the so-called electrical connection between the ranging module 30 and the body 10 means that the ranging module 30 is powered on after it is connected to the body 10. In order to achieve the electrical connection between the ranging module 30 and the body 10, the ranging module 30 also includes a male connector 306 (including multiple ejector pins). The male connector 306 is mounted on the ranging support frame 307. Correspondingly, the body 10 is provided with a female connector 101 (including multiple ejector pin holes) corresponding to the male connector 306. The electrical connection between the ranging module 30 and the body 10 is achieved by connecting the male connector 306 and the female connector 101.

[0053] Furthermore, the ranging module 30 includes a main housing 308, a rotating wheel 311, and a fixing block 314. The rotating wheel 311 is rotatably connected to the main housing 308 and is used to rotate relative to the main housing 308 around an axis in a first direction. The rotating wheel 311 is provided with a gradually thickened claw 3111. The claw 3111 is used to abut against the ranging adapter 20 along the thickness direction when the rotating wheel 311 rotates relative to the main housing 308, so that the main housing 308 and the rotating wheel 311 move in the direction closer to the body 10 when the rotating wheel 311 rotates, so as to realize the connection between the ranging module 30 and the body 10. The fixing block 314 is connected to the rotating wheel 311 and is used to lock the main housing 308 when the rotating wheel 311 rotates to a preset position, thereby achieving the purpose of fixing the rotating wheel 311. At the same time, the fixing block 314 also has the function of a paddle, that is, by paddle the tail of the fixing block 314, the rotating wheel 311 is driven to rotate.

[0054] During installation, first, rotate the wheel 311 of the ranging module 30 to a position where it does not interfere with the ranging adapter 20, and then mount the ranging module 30 onto the body 10. Then, rotate the wheel 311 so that the claw 3111 on the wheel 311 abuts against the ranging adapter 20, thereby causing the main housing 308 and the wheel 311 to move in a direction closer to the body 10 when the wheel 311 rotates, so as to connect the ranging module 30 to the body 10. When the wheel 311 rotates to the preset position, push the fixing block 314 to make the fixing block 314 lock the main housing 308, thereby achieving the purpose of fixing the wheel 311. In this way, the ranging module 30 can be completely fixed onto the body 10.

[0055] In addition, the ranging module 30 can be disassembled by following the reverse order of the above operations. That is, when disassembling, first disconnect the connection between the fixing block 314 and the main housing 308, and then disconnect the connection between the rotating wheel 311 and the ranging adapter 20.

[0056] It should be noted that the aforementioned preset position refers to the position where the rotating wheel 311 rotates to the point where the ranging adapter 20 contacts the limiting structure on the protruding claw 3111, thereby preventing the rotating wheel 311 from rotating further.

[0057] Meanwhile, the aforementioned first direction can be determined by the rotation direction of the rotating wheel 311. Preferably, the first direction can be as follows: Figure 1 The X-axis direction is shown.

[0058] Compared to traditional handheld ranging devices where the ranging module 30 is inconvenient to install and disassemble and has low ranging accuracy, the handheld ranging device provided in this application embodiment allows for convenient and quick installation of the ranging module 30 onto the body 10. The ranging module 30 is positioned using the rotation of the wheel 311 and the movement of the fixing block 314. The ranging module 30 is easy and quick to install and disassemble, and has high positioning accuracy after assembly. The assembled ranging module 30 is powered by the body 10. At the same time, the above installation method can avoid the possibility of changes in the angle between the optical axis of the whole machine and the ranging optical axis, thereby ensuring the parallelism and consistency of the optical axis of the whole machine and the ranging optical axis, which is beneficial to ensuring ranging accuracy.

[0059] It should be noted that the main housing 308 contains a ranging assembly, specifically including a ranging pressure ring 301, a ranging front housing 302, a ranging irregular sealing ring 303, an O-ring seal 304, and a ranging laser module 305. The ranging pressure ring 301, the ranging front housing 302, the ranging irregular sealing ring 303, the O-ring seal 304, and the ranging laser module 305 are assembled and installed inside the main housing 308. Other parts of the ranging assembly are well known to those skilled in the art and will not be discussed further in this document.

[0060] In some embodiments, in order to facilitate the engagement of the ranging adapter 20 with the claw 3111, the ranging adapter 20 includes a base plate 201 and a boss 202 provided on the base plate 201. The boss 202 and the claw 3111 are correspondingly engaged. A preset gap 203 is provided between the boss 202 and the base plate 201. The preset gap 203 is used for the claw 3111 to extend into.

[0061] Preferably, the rotating wheel 311 is provided with two protruding claws 3111 (or more than two protruding claws 3111). The two protruding claws 3111 are distributed along the circumference of the rotating wheel 311. The rotating wheel 311 is a thin-walled cylindrical structure. The two protruding claws 3111 are integrally provided on the inner wall of the rotating wheel 311 and extend from the inner wall towards the center. The line connecting the two protruding claws 3111 passes through the center of the rotating wheel 311.

[0062] Furthermore, the thickness of any protrusion 3111 gradually decreases along the direction of rotation of the rotating wheel 311 during assembly. For example, when the ranging module 30 is assembled with the body 10, the rotating wheel 311 rotates clockwise, so the thickness of both protrusions 3111 gradually decreases clockwise.

[0063] Corresponding to the two protruding claws 3111, the ranging adapter 20 includes two bosses 202, and a preset gap 203 is provided between each boss 202 and the base plate 201 for the protruding claw 3111 to extend into. The dimension of the preset gap 203 along the first direction is greater than the maximum thickness of the protruding claw 3111.

[0064] Understandably, the two gradually thickening protrusions 3111 engage with the two protrusions 202 of the ranging adapter 20, respectively, so that during the rotation of the wheel 311, the protrusions 202 first contact the thinner part of the protrusion 3111 and then the thicker part. In this way, with the body 10 and the ranging adapter 20 as stationary reference points (both fixed), during the rotation of the wheel 311, the wheel 311 and the main housing 308 can move in a direction close to the body 10, thereby completing the assembly of the ranging module 30 and the body 10.

[0065] In some embodiments, in order to facilitate limiting the rotation of the wheel 311, any of the protruding claws 3111 is provided with a protruding edge 3112, the protruding edge 3112 protruding towards the inner side of the protruding claw 3111. Correspondingly, a mating surface 204 is provided between the boss 202 and the base plate 201. The mating surface 204 is used to contact and abut against the protruding edge 3112 to prevent the wheel 311 from rotating.

[0066] Specifically, the protruding edge 3112 is integrally provided at the part with the greatest thickness of the protruding claw 3111, and the protruding edge 3112 protrudes along the inner side of the protruding claw 3111. The inner side refers to the side of the protruding edge 3112 that is close to the other protruding edge 3112. The abutment surface 204 on the boss 202 is located inside the preset gap 203. The abutment surface 204 can be a filling block structure between the boss 202 and the base plate 201.

[0067] In this way, during the rotation of the wheel 311, the boss 202 first contacts the thinner part of the claw 3111, and then contacts the thicker part of the claw 3111, until the abutment surface 204 on the boss 202 contacts the protruding edge 3112 on the claw 3111, at which point the wheel 311 can no longer rotate. At this time, the fixing block 314 can be pushed toward the main shell 308, so that the main shell 308 and the fixing block 314 are engaged, thereby achieving the purpose of fixing the wheel 311.

[0068] In some embodiments, in order to facilitate the positioning of the main shell 308, the main shell 308 is provided with two first limiting blocks 3081. The two first limiting blocks 3081 are arranged opposite each other and both extend along a first direction. Correspondingly, the ranging adapter 20 is provided with a second limiting block 205 and two limiting spaces 206. The two limiting spaces 206 are respectively located on both sides of the second limiting block 205. The second limiting block 205 is used to fit between the two first limiting blocks 3081, and the two limiting spaces 206 are respectively used to fit with the two first limiting blocks 3081 to fix the main shell 308.

[0069] It should be noted that during the rotation of the rotating wheel 311, as the rotating wheel 311 and the main shell 308 move in the direction close to the fuselage 10, on the one hand, the male head 306 on the main shell 308 and the female head 101 on the fuselage 10 are connected and powered on; on the other hand, the two first limiting blocks 3081 on the main shell 308 are respectively engaged with the two limiting spaces 206, so that the main shell 308 can be fixed to the fuselage 10.

[0070] In some embodiments, the ranging module 30 further includes a pressure roller 310 and a first elastic member 309. The pressure roller 310 is movably mounted inside the rotating wheel 311 and is used to abut against the ranging adapter 20 when the rotating wheel 311 rotates. The first elastic member 309 abuts between the pressure roller 310 and the main housing 308 and is used to provide elastic force to the pressure roller 310, so that the pressure roller 310 tends to move closer to the fuselage 10.

[0071] Specifically, the first elastic element 309 can be a wave spring. During the rotation of the rotating wheel 311, the end face of the boss 202 of the ranging adapter 20 will press against the pressure wheel 310. As the rotating wheel 311 and the main housing 308 move in the direction close to the body 10, the pressure wheel 310 moves in the direction away from the body 10, and the wave spring is compressed. In this way, the wave spring can provide elastic force to the pressure wheel 310. This not only makes the pressure wheel 310 tend to move closer to the body 10 (the ranging adapter 20 always abuts against the inner wall of the claw 3111 on the rotating wheel 311), but also makes it easy to disassemble the ranging module 30 (when the claw 3111 on the rotating wheel 311 releases the restriction on the boss 202 of the ranging adapter 20, the ranging module 30 automatically pops out under the action of elastic force).

[0072] In addition, the wave spring design provides a good feel during operation, making it convenient and effortless.

[0073] In some embodiments, in order to facilitate the guidance of the pressure roller 310, the pressure roller 310 is provided with lugs 3103. The number of lugs 3103 is preferably two. Both lugs 3103 are provided with through holes 3104. Correspondingly, the ranging module 30 also includes two connecting posts 312. The two connecting posts 312 pass through the two through holes 3104 and are connected to the main housing 308.

[0074] The two connecting posts 312 serve as guides, ensuring that the pressure roller 310 moves along its axial direction (first direction). Each of the two connecting posts 312 has an annular protrusion at its end, which prevents the pressure roller 310 from detaching from the connecting post 312.

[0075] In some embodiments, in order to facilitate the sliding of the wheel 311, the main housing 308 is provided with a slide rail 3082, and the wheel 311 is provided with a plurality of protrusions 3113 distributed along the circumferential direction (preferably four protrusions 3113). Each protrusion 3113 is screwed into the slide rail 3082 and can slide along the slide rail 3082.

[0076] Correspondingly, the main housing 308 is also provided with a limiting protrusion 3083, the limiting protrusion 3083 is provided with a notch 3084, and a tail baffle 313 is detachably connected to the rotating wheel 311. The tail baffle 313 is used to rotate within the notch 3084 to drive the rotating wheel 311 to rotate, while limiting the rotation position of the rotating wheel 311 and preventing the protrusion 3113 from disengaging from the slide rail 3082.

[0077] Specifically, the rotating wheel 311 is rotated to a certain angle and inserted into the main housing 308, such as... Figure 12As shown; then, the rotating wheel 311 rotates to a position 180 degrees parallel to the main shaft (the optical axis of the whole machine), and the four protrusions 3113 of the rotating wheel 311 rotate into the slide rail 3082. After that, the tail baffle 313 is installed on the rotating wheel 311. At this time, the rotating wheel 311 can slide on the track in the limited position, as shown. Figure 13 As shown.

[0078] In some embodiments, in order to facilitate the engagement and connection between the fixing block 314 and the main housing 308, the main housing 308 is provided with a locking block 3085, the fixing block 314 is provided with a locking slot 3141 and a limiting hole 3142 (waist-shaped hole), and the tail baffle 313 is provided with a guide post 315. The guide post 315 is located in the limiting hole 3142. The fixing block 314 moves within the limited range of the limiting hole 3142. When the rotating wheel 311 rotates to the preset position (the abutment surface 204 on the boss 202 contacts the protruding edge 3112 on the protruding claw 3111, and the rotating wheel 311 can no longer rotate), the fixing block 314 is pushed in the second direction so that the locking slot 3141 locks the locking block 3085.

[0079] The aforementioned second direction can be determined by the rotational position of the rotating wheel 311. Preferably, the second direction can be as follows: Figure 1 The Y-axis direction is shown.

[0080] In some embodiments, the fixing block 314 is further provided with a locking groove 3143, which is larger at both ends and smaller in the middle. The tail baffle 313 is provided with a receiving groove 3131, in which a ball 316 and a second elastic member 317 are provided. The second elastic member 317 can be a compression spring. The ball 316 is used to slide along the locking groove 3143. The second elastic member 317 abuts between the ball 316 and the tail baffle 313. The second elastic member 317 is used to provide elastic force to the ball 316, so that the ball 316 has a tendency to disengage from the tail baffle 313.

[0081] In this way, in the initial position, the guide post 315 is located at the left end of the limiting hole 3142, and the ball 316 is located at the left end of the engaging groove 3143. As the fixing block 314 moves to the left and completes the engaging connection with the main shell 308, the guide post 315 is located at the right end of the limiting hole 3142, and the ball 316 is located at the right end of the engaging groove 3143.

[0082] Understandably, the arrangement of the ball 316 and the second elastic element 317 can provide a "click" sound when the fixing block 314 and the main shell 308 are engaged, thereby indicating to the operator that the fixing block 314 and the main shell 308 have been engaged.

[0083] In addition, a cover plate 319 is provided on the fixing block 314. The cover plate 319 is connected to the fixing block 314. A gasket 318 is provided on the inner side of the cover plate 319. The gasket 318 is a silicone gasket.

[0084] In some embodiments, in order to facilitate the assembly of the pressure roller 310, the pressure roller 310 includes an annular body 3101, and the annular body 3101 is provided with a plurality of grooves 3102 distributed along the circumferential direction. The grooves 3102 are used to avoid the protrusions 3113 on the rotating wheel 311, so that the pressure roller 310 can be installed inside the rotating wheel 311.

[0085] In summary, this application provides a handheld ranging device that is fixed by rotation. The ranging module 30 is mounted on the body 10 by limiting its position in the X-axis direction. The rotating wheel 311 is rotated (i.e., rotated around the X-axis) to a certain position by the tail baffle 313 and then fixed. Then, the fixing block 314 is pushed to move in the Y-axis direction, effectively limiting the displacement of the ranging module 30 in the Y-axis direction. After installation, the ranging module is powered by the entire device. This application ensures the parallelism of the ranging module 30 and the body 10 along the X-axis through end-face contact, and ensures the parallelism of the ranging module 30 and the body 10 along the Y-axis through two sets of limiting devices. This ensures the parallelism and consistency of the optical axis of the entire device and the ranging optical axis, thereby guaranteeing ranging accuracy.
