Description

Technical Field

[0001] The utility model relates to the technical field of surveying and mapping application equipment, in particular to a detachable measuring robot protection device. Background Art

[0002] Measuring robots, such as intelligent total stations, are widely used in precision engineering measurement or deformation monitoring. However, measuring robots are expensive and may be damaged due to various factors during field measurement, which may damage instrument components and reduce accuracy, or even lead to equipment scrapping, resulting in significant losses.

[0003] An airbag is a device that uses the compressibility of gas or the fluidity of water to achieve elasticity by filling a flexible rubber capsule with compressed air or water. Airbags can be used in various mechanical devices to buffer vibration, control movement or increase pressure. Compared with elastic elements with the same function, such as steel springs, airbags have a simple structure, reliable operation, no need for complex parameter calculations and structural design, no static deflection, easy use and maintenance, and a long service life. In practical applications, airbags have a variety of uses, such as vibration isolation, shockproof, lifting, clamping and anti-swing, etc. Their usage and quantity depend on the specific equipment.

[0004] Therefore, airbags are installed on some total stations or tripods. When they fall over, the airbags will expand rapidly to achieve a protective effect. However, these airbags are basically installed on the periphery of the base where the measuring unit is installed, that is, the area between the measuring unit and the tripod. The airbag expands at this position, and the expansion direction is difficult to control. It is mostly radial or lateral expansion. Although it can play a certain protective role when it falls over, it cannot effectively cover the measuring unit. In addition, these airbag protection devices are mostly fixed structures, which cannot be disassembled separately, and cannot be switched between multiple devices. Summary of the invention

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the utility model to clearly and completely describe the technical solution of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] In the description of the present invention, it should be noted that the directions or positional relationships indicated by the terms "middle", "upper", "lower", "left", "right", "inner", "outer", etc. are based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance. Example 1

[0031] like Figure 1 to Figure 5 As shown, a detachable measuring robot protection device includes a device shell 4, a snap-fit ​​member 3 is provided at the bottom of the device shell 4, and the snap-fit ​​member 3 is detachably mounted on a handle 2 above the measuring robot 1, and the measuring robot 1 is usually arranged on a tripod; a receiving groove 5 is provided in the surrounding walls of the device shell 4, and the receiving groove 5 has a notch opening facing downward, and an airbag 6 in a contracted state is provided in the receiving groove 5; an automatic inflation component is provided in the device shell 4, and the automatic inflation component is connected to the airbag 6 through an inflation tube 7 and is used for inflating the airbag 6; a circuit board 11 and a posture sensor 12 electrically connected to the circuit board 11 are also provided in the device shell 4, and the automatic inflation component is also electrically connected to the circuit board 11.

[0032] This measuring robot protection device uses the posture sensor 12 to sense the state of the measuring robot 1. When the measuring robot 1 falls over and is in a weightless state, the airbag 6 will receive a trigger signal and quickly inflate and pop out, wrapping the measuring robot 1 on all sides to reduce the damage to the measuring robot caused by the impact when the measuring robot 1 falls.

[0033] The protective device can be detachably mounted on the handle 2 of the measuring robot, is convenient to assemble and disassemble, and is easy to use. Moreover, the entire protective device is small in size, light in weight, and easy to carry, especially during outdoor operations, and does not increase the user's mass burden too much.

[0034] This protective device not only has a simple appearance, but also has fewer internal parts, is easy to manufacture, has a low manufacturing cost, and can be widely used in practice; this protective device can not only be adapted to different types of measuring robots, but can also be used for other types of surveying and mapping instruments to provide safety protection for measuring components.

[0035] Since the protection device is arranged above the measuring robot, in the airbag expansion mode, it is hoped that the airbag will expand downward and cover the measuring units such as the lens. Therefore, the accommodating groove 5 is arranged in the peripheral wall of the device shell, with the groove facing downward, and the airbag 6 is arranged in the accommodating groove 5. When it is inflated, it can quickly pop out from the groove and cover the periphery of the entire measuring unit; the accommodating groove 5 not only provides a space for accommodating and connecting the airbag 6, but also can select the direction for the airbag expansion with the cooperation of the groove, so that the airbag will not expand upward or laterally.

[0036] The setting of the posture sensor 12 can effectively realize the perception of the posture of the measuring robot; during the operation, by sensing the posture of the measuring robot, the airbag can be quickly popped out when the measuring robot topples over due to various external factors, thereby reducing the damage caused by falling and impact; the posture sensor 12 feeds back the monitored posture signal to the circuit board 11, and the controller (signal processing unit) on the circuit board 11 determines whether the posture of the measuring robot is normal or whether there is an abnormal state such as tipping over according to the received posture signal. If an abnormality occurs, an inflation command is issued to the inflatable component, and the inflatable component then uses the inflation tube to rapidly inflate the airbag 6, and the airbag 6 inflates and pops out and quickly covers the measuring unit to form protection.

[0037] The attitude sensor 12 includes but is not limited to a three-axis gyroscope, a three-axis accelerometer, a three-axis electronic compass and other motion sensors, and outputs three-dimensional attitude data in real time through the relevant algorithms of the internal processor and special data fusion technology. The airbag 6 can be made of TPU (thermoplastic polyurethane), which is an environmentally friendly material with good elasticity and wear resistance and can be reused. The gas filled in the airbag 6 can be an inert gas.

[0038] Furthermore, the fastener 3 is a plurality of clamps, a plurality of straps or a plurality of claws, or a combination of these. Such fasteners are easy to use and install, and are not limited to the type of fasteners in practice, provided that the device housing can be firmly fixed to the handle.

[0039] Furthermore, the device housing 4 is a rectangular structure, and the receiving groove 5 is a circumferential rectangular ring groove. Although the device housing can also be a circular or elliptical structure, in combination with the long strip form of the measuring unit of the measuring robot, a simpler rectangular structure can be selected as the housing, and the receiving groove 6 is a rectangular ring groove arranged around the circumference.

[0040] Furthermore, a power supply 13 is provided inside the device housing 4, such as a rechargeable lithium battery. The power supply 13 is connected to the circuit board 11, the posture sensor 12 and the automatic inflation component. A switch connected to the circuit board 11 or the power supply 13 is also provided below the device housing 4.

[0041] The power supply 13 can supply power to the circuit board, the posture sensor and the automatic inflation component. The switch 14 can be a general on / off switch or a power switch. By setting the switch 14, the entire device can be turned off or started. The entire protection device will only work after the switch 14 is turned on. After the switch 14 is turned off, the protection device can be loaded and unloaded, and moved.

[0042] Furthermore, an openable and closable cover 15 is provided below the device housing 4. The cover 15 is connected to the device housing 4 by a number of screws and can be opened when needed. The switch 14 can be arranged on the cover 15 for easy use, which can also prevent the switch 14 and the cover 15 from being exposed above, so as to prevent rainwater from entering the device housing when the weather is bad.

[0043] The circuit board can be installed on the inner wall of the cover or the device shell through connecting columns. Some installation positions can be set on the inner wall of the cover or the device shell to install the power supply, posture sensor and automatic inflation component. Some mounting seats, connectors and other auxiliary connection and installation can be configured.

[0044] Furthermore, the automatic inflation component includes a gas collecting bottle 8 arranged in the device housing 4, the output end of the gas collecting bottle 8 is connected to the inflation tube 7 and an inflation valve 9 is provided on the output end, the inflation valve 9 is connected to a drive motor 10, and the drive motor 10 is electrically connected to the circuit board 11.

[0045] The automatic inflation component receives the signal generated by the posture sensor and can control the drive motor 10 to drive the inflation valve to open and close, so that the gas collecting bottle 8 quickly releases gas to quickly eject the airbag 6. In some embodiments, the inflation valve can also be a solenoid valve. In this case, the drive motor can be omitted and the solenoid valve can be directly used to receive the opening and closing instructions.

[0046] In some embodiments, Figure 4 The slot is provided with a virtual shielding cover 16 or a shielding film. Both the shielding cover 16 and the shielding film are relatively thin structures, which can temporarily close the slot to prevent the airbag 6 from being exposed. Since the shielding cover 16 and the shielding film are virtual connections (for example, preset breakpoint lines), once subjected to external forces, such as the impact force of the airbag expansion, they can be opened instantly without affecting the ejection of the airbag.

[0047] This detachable measuring robot protection device can be installed on the handle of the measuring robot through the ring fastener after the measuring robot is set up, and it can start working by turning on the switch. It should be noted that this protection device must be installed above the handle to prevent obstruction of the rotation of the measuring robot telescope and blocking the telescope's line of sight; and the device must be turned off before disassembly to prevent the posture sensor from detecting an abnormal posture of the device itself and causing the airbag to pop out.

[0048] The airbag of the protective device will pop out downwards and wrap around the measuring robot to reduce the impact after the measuring robot falls over. The measuring robot protective device is an integrated product of lithium battery, attitude sensor, automatic inflation component and airbag light. The lithium battery powers the entire device; the automatic inflation component inflates the airbag; the attitude sensor is used to detect the attitude of the measuring robot. Example 2

[0049] The difference between this embodiment and embodiment 1 is that a guide structure is provided below the device housing, as shown in FIG. Figure 6 As shown, a circle of guide cover plates 17 is arranged inwardly below the notch, and the guide cover plates 17 are arranged obliquely outwardly.

[0050] By providing the guide cover plate 17 , the ejected airbag 6 can be guided to expand downward and outward, thereby preventing the airbag from expanding unrestrictedly toward the middle and directly hitting the measuring unit.

[0051] Furthermore, the guide cover plates 17 on both sides are provided with card slots, and the card slots are used to be connected to the handle 2. Such an installation method cooperates with the snap fasteners to more stably install it on the handle of the measuring robot.

[0052] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
