Description

Technical Field

[0001] This invention relates to the field of engineering surveying equipment technology, and more specifically, to an airbag protection device for an automatic total station. Background Technology

[0002] Total stations, as engineering surveying equipment, are expensive and require high precision, making them extremely prone to damage. Collisions or tipping over during use can cause damage. While there are devices on the market designed to protect total stations, such as the invention patent CN112212840B which discloses a total station for urban geological surveying and mapping, the invention includes an adjustment base. An organic body is movably connected to the middle of the upper surface of the adjustment base, and a rotating base is movably connected to the lower surface of the adjustment base. A piston rod is fixedly connected to the other end of the rotating base, and an adjustment rod is movably sleeved at the other end of the piston rod. A piston block is movably sleeved at the upper end of the piston rod's inner cavity. This invention connects a collapse protection mechanism with an automatic leveling mechanism. When using a tripod, if an air supply device is required, the tripod can be tilted and the adjustment rod manually pulled out to its full length before leveling the base. This allows for the recirculation of internal gas. Furthermore, when the equipment is stowed, the cushioning airbag extends to its maximum, acting as a storage unit for the total station. There is no need to worry about the corrosion of the tripod's internal components due to ambient humidity at the measurement site. However, existing solutions using airbags to protect the total station from tipping typically have the airbag directly wrapped around the side of the total station. This occupies a significant amount of space, requiring ample installation space in the total station design. Conversely, if installed by folding, the airbag's poor design can prevent rapid inflation, potentially causing it to become stuck. Summary of the Invention

[0003] This invention discloses an airbag protection device for an automatic total station, which aims to improve the problem that the existing airbag device has an unreasonable structure, which makes the airbag unable to expand and deploy quickly and easily impact the total station.

[0004] The present invention adopts the following solution:

[0005] This application provides an airbag protection device for an automatic total station, including an airbag suitable for installation on the outside of the total station, a detection device, an inflation device, and a control device. The inflation device connects the airbag and the detection device. When the detection device is triggered, it is adapted to control the inflation device to inflate the airbag through the control device. The airbag is adapted to be folded and installed on the outside of the total station, and includes a wrapping part and a protective part. The wrapping part is connected below the protective part to wrap the detection device and the inflation device. The protective part includes a protective body connected to the wrapping part on the lower side and a petal-shaped bladder connected to the protective body on the upper side. The protective body has multiple connecting points inside to form multiple interconnected air chambers inside the protective body to reduce the amount of air required to fill the protective body. The petal-shaped bladder includes multiple small airbags surrounding the upper side of the protective body. The multiple small airbags extend outward from the connection point of the protective body and gradually decrease in width to form the petal-shaped bladder that wraps inward when inflated.

[0006] Furthermore, the protective part forms an airbag space for containing gas through a double-layer airbag fabric. The periphery of the double-layer airbag fabric is connected by a double-layer jointing structure to plan and define the shape of the air chamber and improve the pressure holding effect.

[0007] Furthermore, the surface of the airbag fabric has a coating to improve the pressure-holding effect.

[0008] Furthermore, the protective body is provided with two rows of parallel connecting points of the joint tissue, so that when folding, the connecting line formed by each row of connecting points of the joint tissue is used as the folding line.

[0009] Furthermore, the two fold lines divide the protective body into an upper air chamber connected to the petal-shaped bladder, a lower air chamber connected to the wrapping part, and an intermediate air chamber located between the upper and lower air chambers. When the protective body is folded, the intermediate and lower air chambers are folded in the forward direction according to the fold lines, while the upper and intermediate air chambers are folded in the reverse direction. The petal-shaped bladder is rolled up from top to bottom in the same direction as the upper air chamber, and the rolling width is the same as or similar to the folded width of the protective body.

[0010] Furthermore, the folded protective portion is adapted to be placed inside the package portion as described above.

[0011] Furthermore, the lower air chamber is provided with an air inlet connected to the air inflation device.

[0012] Furthermore, the airbag is provided with connecting buckles at both ends that can be connected to each other and whose length is adjustable.

[0013] Furthermore, the inflation device and the detection device are connected to a control circuit, which is connected when the connecting buckles are engaged.

[0014] Furthermore, after the airbag is inflated, the end of the petal-shaped bladder is higher than the main body of the total station.

[0015] Beneficial effects: This invention employs a detection device that, when the instrument is impacted or dropped, controls an inflation device to release gas to inflate the airbag. The inflated airbag quickly expands, enveloping the instrument and forming a cushion of a certain thickness around it, providing a buffer and protecting the instrument from damage. The foldable protective body folds in a specific manner for easy and secure deployment without jamming. A petal-shaped bladder surrounds the upper part of the protective body, allowing the airbag to quickly envelop the total station upon deployment, requiring less gas. The deployed airbag provides 360° all-around protection, effectively and comprehensively protecting the equipment. Attached Figure Description

Detailed Implementation

[0017] Combination Figures 1 to 8 As shown, this embodiment provides an airbag protection device for an automatic total station, including an airbag 24 suitable for installation on the outside of the total station 1, a detection device 21, an inflation device 22, and a control device. The inflation device 22 connects the airbag 24 and the detection device 21. When the detection device 21 is triggered, it is adapted to control the inflation device 22 to inflate the airbag 24 through the control device. The airbag 24 is adapted to be folded and installed on the outside of the total station 1, and includes a wrapping part 241 and a protective part. The wrapping part 241 is connected below the protective part to wrap the detection device 21 and the inflation device 22. The protective part includes a lower side and... The protective body 2421 is connected to the wrapping part 241, and the petal-shaped bladder 2422 is connected to the upper side of the protective body 2421. The protective body 2421 has a plurality of connecting tissue connection points 2424 inside to form a plurality of interconnected air chambers 2423 inside the protective body 2421 to reduce the amount of air required to fill the protective body 2421. The petal-shaped bladder 2422 includes a plurality of small air bladders surrounding the upper side of the protective body 2421. The small air bladders extend outward from the connection point of the protective body 2421 and gradually decrease in width to form an inwardly wrapping petal-shaped bladder 2422 when inflated.

[0018] Combination Figures 1 to 3 As shown, in this embodiment, the total station 1 is an existing device, and a protective device 2 is installed on the side of the total station 1. The protective device 2 includes an airbag 24, a detection device 21, an inflation device 22, a control device, and a battery. The control device is connected to the detection device 21, the inflation device 22, and the battery, so as to control the inflation device 22 to quickly release gas after receiving a trigger signal from the detection device 21. Here, the inflation device 22 can be a compressed gas cylinder, and the detection device 21 can use an existing acceleration sensor or a combination of multiple sensors to monitor data such as acceleration, vibration, and impact force. When the measuring device is impacted and falls, the control device automatically determines whether the total station 1 needs protection according to a preset algorithm. When it is determined that protection is needed, the inflation device 22 is activated, causing the airbag 24 to inflate and unfold, wrapping the total station 1 and preventing damage. Detecting whether an object is tipped over using sensors is existing technology, and its specific structure and sensor model are not limited here.

[0019] Combination Figures 4 to 7As shown, in this embodiment, the airbag 24 includes a wrapping part 241 and a protective part. The wrapping part 241 is used to wrap the airbag 24, the detection device 21, the inflation device 22, the control device, and the battery, and can also wrap the folded protective part. The wrapping part 241 has a reserved channel for the protective part to unfold. The protective part includes a protective body 2421 connected to the wrapping part 241, and a petal-shaped bladder 2422 connected to the protective body 2421. Specifically, the protective part is composed of separable double-layer airbag fabric, and the periphery of the airbag fabric is a double-layer bonding structure, which is integrally formed during weaving, thereby connecting the double-layer airbag fabric to form the airbag 24. The layout of the separable double-layer airbag fabric and the double-layer bonding structure forms an inflatable airbag body, and a coating is applied to the surface of the airbag 24. Since the body does not require sewing, i.e., there are no needle holes, an airbag with better pressure retention can be formed after inflation. Furthermore, the airbag fabric surface has a coating to improve the pressure retention effect. The airbag 24 has a good pressure-holding effect, which can prevent injury from repeated rolling. After use, the airbag 24 can be deflated and folded again for repeated use, saving costs.

[0020] Continue to combine Figures 4 to 7 As shown, multiple interconnected air chambers 2423 are formed within the protective body 2421 through connecting points 2424. Specifically, the protective body 2421 has two rows of parallel connecting points 2424, so that during folding, the connecting lines formed by each row of connecting points 2424 serve as the folding lines. In one embodiment, the upper and lower rows of connecting points 2424 are staggered, which can further improve the limitation on the height of the airbag fabric when unfolded, and the two rows of connecting points 2424 will not overlap when folded, reducing the thickness after folding. The connecting point 2424 is used to connect the double-layer airbag fabric to limit the height of the airbag fabric's expansion. This allows the originally spherical airbag to be constrained into a flat airbag with uniform thickness (similar to a soda cracker), significantly reducing the amount of gas required. For example, in this embodiment, only one compressed gas cylinder is needed to fully fill it, and the inflation speed of the airbag 24 is greatly increased, allowing it to quickly form a protective structure the moment the total station 1 is impacted, avoiding the problem of the airbag not fully inflating after the total station 1 has already tipped over. It should be noted that in this embodiment, the connecting point 2424 also allows the lower air chamber to form two rows of chambers, ensuring uniform thickness after inflation and consistent force direction during expansion, resulting in symmetrical air chambers.

[0021] The petal-shaped bladder 2422 is connected to the upper part of the protective body 2421. Specifically, the petal-shaped bladder 2422 includes a plurality of small air bladders surrounding the upper side of the protective body 2421 and connected at the bottom end. The small air bladders extend outward from the connection point of the protective body 2421 and gradually decrease in width to form an inwardly wrapped air bladder when inflated. This creates gaps between adjacent small air bladders, requiring less air and allowing for rapid inflation. In one embodiment, the ends of the small air bladders are provided with lugs to connect the tails of adjacent small air bladders, so that they automatically form an inwardly wrapped air bladder when inflated. In a preferred embodiment, after the air bladder 24 is inflated, the ends of the petal-shaped bladder 2422 are higher than the main body of the total station 1, so that the air bladder 24 can completely cover the main body of the total station 1 after unfolding, providing multi-directional protection for the total station 1.

[0022] Continue to combine Figures 4 to 8 As shown, in this embodiment, the two fold lines divide the protective body 2421 into an upper air chamber 2423 connected to the petal-shaped sac 2422, a lower air chamber 2423 connected to the wrapping portion 241, and an intermediate air chamber 2423 located between the upper and lower air chambers 2423. When the protective body 2421 is folded, the intermediate and lower air chambers 2423 are folded in the forward direction according to the fold lines, while the upper and intermediate air chambers 2423 are folded in the reverse direction. The petal-shaped sac 2422 is rolled up from top to bottom in the same direction as the upper air chamber 2423, and the rolling width is the same as or similar to the folded width of the protective body 2421. There are gaps between adjacent connecting tissue points 2424 to allow communication between the air chambers 2423. The folded protective portion is suitable for placement within the wrapping portion 241. This folding method allows the protective body 2421 to be filled with gas first when the inflation device 22 is inflated. Because the protective body 2421 is folded in both directions, its three-layered air chambers 2423 do not jam during unfolding, allowing for rapid expansion. Then, gas enters the petal-shaped bladders 2422 to inflate each small air bladder. Since the small air bladders fold outwards from top to bottom, they are not affected during unfolding and can expand quickly, wrapping around the total station 1 from the outside in, like a chrysanthemum. During unfolding, the air bladder 24 completely encloses the entire total station 1, and the unfolding direction is stable upwards during inflation, preventing impact on the total station 1 and providing better equipment protection.

[0023] The lower air chamber 2423 is provided with an air inlet 2425 connected to the inflation device 22 to ensure that it unfolds from the lower right to the upper right when unfolded, and to facilitate connection with the inflation device 22 provided in the wrapping part 241.

[0024] In this embodiment, the airbag 24 is provided with interconnectable and length-adjustable connecting buckles 23 at both ends. The airbag 24 is fastened via the connecting buckles 23, allowing for convenient installation and disassembly. The control device is equipped with a start switch, which is located within the connecting buckles 23. Therefore, the entire protection device 2 is activated only when the connecting buckles 23 are engaged. Specifically, the inflation device 22 and the detection device 21 are connected to a control circuit that connects the start switch and the control device. The control circuit is connected when the connecting buckles 23 are engaged, thus activating the entire protection device 2. When the connecting buckles 23 are disconnected, the control circuit is also disconnected, ensuring that the protection device 2 is in the active state when installed on the total station 1.

[0025] During operation, the folded airbag 24 is placed inside the wrapping section 241, in an uninflated state, shaped like a belt. The airbag 24 is wrapped around the total station 1 or other measuring equipment, adjusted to the appropriate length to ensure it tightly wraps around the equipment. The switch is then activated by fastening the connecting buckle 23. When the instrument is impacted or dropped, the sensor detects a signal, triggering the control device to release gas from the inflation device 22 to inflate the airbag 24. The inflated airbag 24 quickly unfolds, enveloping the instrument and forming a cushion of a certain thickness around it, providing a buffer and protecting the instrument from damage.

[0026] The protective device 2 of this invention has the following advantages: it is simple to use, simply attaching to the measuring equipment; it is highly adaptable, reusable, and low in cost; the device has a fully automatic monitoring function, capable of instantaneous activation for timely protection; the airbag 24 has pressure-holding capacity, providing multiple protections in the event of a rollover; after deployment, the airbag provides 360° all-around wrapping, effectively protecting the equipment; the airbag is a one-time woven fabric, simplifying the weaving process.

All technical solutions that fall within the scope of the present invention are within the scope of protection of the present invention.
