Description

Technical Field

[0001] This utility model relates to the field of laser ranging technology, and in particular to a laser ranging device with light emission and light emission isolation. Background Technology

[0002] A laser rangefinder is a high-precision device that uses a laser beam to measure the distance to a target. It achieves rapid and accurate distance detection by calculating the time difference or phase difference between the emitted and reflected light.

[0003] When distance measurement is required, the traditional method is to emit a laser beam from the transmitter of a laser rangefinder and receive the reflected light through the receiver, and then calculate the distance using a formula. However, during use, the measurement results deviate from the actual results due to the communication between ambient light and the emitted light, affecting the accuracy of distance monitoring. Therefore, this solution proposes a laser rangefinder with isolation between the emitted and received light to solve the above problems. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] This utility model provides, for example Figure 1-5 The laser ranging device with light emission and emission isolation shown includes: The bracket 1 has a mounting groove 101 on its top, and mounting components 6 are symmetrically arranged on its front and back sides. Laser transceiver 7 is mounted on one side of bracket 1; The receiving lens tube 2 is inserted and connected inside the mounting slot 101; The transmitting lens tube 3 is located on the front of the receiving lens tube 2 and is inserted into the inside of the mounting slot 101. A light-transmitting isolation component is provided on the other side of bracket 1. A fixing component is provided on top of the receiving lens tube 2 and the transmitting lens tube 3.

[0021] It should be noted that the laser transceiver 7 is an existing active sensor system that detects the distance, orientation, and three-dimensional information of the surrounding environment by emitting a laser beam and receiving the reflected signal from the target. The transmitting lens 3 is responsible for collimating, shaping, and directionally projecting the laser beam generated by the laser onto the target area. The receiving lens 2 is used to efficiently collect the weak laser signal reflected by the target and suppress background light interference through a filter to achieve high-sensitivity signal conversion. In use, both the receiving lens 2 and the transmitting lens 3 are inserted into the mounting slot 101. The receiving lens 2 and the transmitting lens 3 are fixed inside the mounting slot 101 by a fixing component. The optical isolation between the transmitter and receiver is achieved by an isolation light-transmitting component, and the receiver is isolated from the external space to block external stray light and internal crosstalk, ensuring signal purity.

[0022] Specifically, the fixing components include an adhesive groove 4 opened on the top of the receiving lens tube 2 and the transmitting lens tube 3. The adhesive groove 4 is used for adhesive to penetrate into the top of the receiving lens tube 2 and the transmitting lens tube 3. The top of the bracket 1 is provided with a cover groove 104, and an upper cover plate 5 is inserted and connected inside the cover groove 104.

[0023] It should be noted that the adhesive dispensing groove 4 is used to fix the receiving lens barrel 2 and the transmitting lens barrel 3 with optical adhesive, which plays a role in structural bonding, vibration damping and environmental sealing. The lens barrel, bracket 1 and top cover plate 5 are firmly bonded together by high-strength optical adhesive (such as epoxy resin or silicone), which ensures the long-term stable alignment of the transmitting and receiving optical paths and avoids the offset caused by mechanical vibration or temperature changes. At the same time, the elasticity of the adhesive layer can absorb some of the impact energy and reduce the impact of external vibration on measurement accuracy. In addition, the adhesive dispensing can also form a sealing barrier to prevent dust, moisture and intrusion into the optical components, and improve the reliability of the laser transceiver 7 in complex environments.

[0024] Specifically, the light-transmitting component includes a receiving hole 102 on the other side of the bracket 1 and an emission hole 103 on the other side of the bracket 1. Both the receiving hole 102 and the emission hole 103 are interconnected with the mounting groove 101.

[0025] It should be noted that the receiving aperture 102 is connected to the receiving lens tube 2, and the transmitting aperture 103 is connected to the transmitting lens tube 3, thereby isolating the transmitted and received light.

[0026] Specifically, the mounting component 6 includes mounting plates 602 that are symmetrically fixedly connected to the front and back of the bracket 1, and mounting holes 601 are symmetrically opened on both sides of the mounting plate 602.

[0027] It should be noted that there are two mounting plates 602, which are symmetrically fixed to the bottom of the front and back of the bracket 1. The mounting plates 602 are integrally formed with the bracket 1 during manufacturing. The mounting holes 601 are provided for bolts to pass through the mounting plates 602, and the position of the mounting plates 602 is fixed by bolts.

[0028] Specifically, a screw 8 is provided at the connection between the bracket 1 and the laser transceiver 7, and the screw 8 is used to fix the position of the laser transceiver 7.

[0029] It should be noted that when it is necessary to fix the position of the laser transceiver 7, the laser transceiver 7 should first be moved to fit against the bracket 1, and then the laser transceiver 7 should be fixed in position by passing the screws 8 through the laser transceiver 7 and the bracket 1 in sequence.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
