Description

A protective structure for a vehicle-mounted mapping device Technical Field

[0001] This utility model relates to the field of surveying and mapping technology, specifically to a protective structure for a vehicle-mounted surveying and mapping device. Background Technology

[0002] Vehicle-mounted surveying refers to installing surveying equipment on a vehicle to quickly and efficiently acquire information about roads and their surroundings, often used in highway planning. Currently, surveying equipment is typically mounted directly on the roof of the vehicle. Since surveying is conducted outdoors, it frequently encounters rain, snow, and fog. In such conditions, tarpaulins must be used to cover the equipment to prevent damage from rain, snow, and fog. This requires manually setting up the tarpaulins, which cannot be done while the vehicle is in motion, hindering timely protection of the equipment and presenting both inconvenience and inherent risks. Summary of the Invention

[0003] The present invention aims to address the aforementioned shortcomings by providing a protective structure for a vehicle-mounted mapping device. This structure comprises a chassis and a cargo box mounted on the chassis. A mounting base is fixedly installed at one end of the cargo box near the driver's cab. A lifting mechanism is mounted on the mounting base, and a mapping device is fixedly installed at the top of the lifting mechanism. An exit is provided on the top of the cargo box corresponding to the mapping device, and a sliding cover is provided at the exit. An operating area is provided at the end of the cargo box furthest from the driver's cab.

[0004] To facilitate control of the lifting mechanism's raising and the top cover's sliding, a limit switch one is installed on the mounting base, and a limit switch two that cooperates with the top cover is fixedly installed at the end of the top of the body away from the driver's cab. Limit switch one, limit switch two, the lifting mechanism, and the top cover's sliding drive mechanism are all connected to the control device.

[0005] To ensure a tighter contact between the top cover and the outlet, fixed plates are arranged parallel to each other on both sides of the outlet. The fixed plates are provided with a front slide groove and a rear slide groove with identical structures. The rear slide groove has a downward-sloping inclined groove at the end near the cab. The front slide groove and the rear slide groove are respectively provided with pulleys, and the pulleys are connected to the top cover.

[0006] To improve the sealing between the top cover and the outlet, a sealing strip is provided at the contact point between the bottom of the top cover and the outlet.

[0007] To facilitate the maintenance of the surveying device, an inspection door is provided on the side wall of the compartment corresponding to the location of the surveying device.

[0008] This utility model has the following beneficial effects:

[0009] This utility model installs the surveying device inside the vehicle body. When in operation, the surveying device is raised and positioned outside the vehicle body via a lifting mechanism. When not in operation, the top cover seals the outlet, effectively protecting the surveying device and avoiding the damage that could easily occur when the surveying device is directly installed on the roof of the vehicle.

[0010] This utility model is equipped with limit switch one, limit switch two and control device, which can be operated with one button in the cab, making the raising and retraction of the surveying device more convenient and faster. During surveying, if the weather changes, the surveying device can be retracted into the cargo box at any time to avoid damage to the surveying device caused by the weather.

[0016] The following drawings will disclose several embodiments of this utility model. For clarity, many physical details will be described in the following description. However, it should be understood that these physical details should not be used to limit this utility model. That is, in some embodiments of this utility model, these physical details are not essential. In addition, for the sake of simplicity, some conventional structures and components will be shown in the drawings in a simple schematic manner.

[0017] Furthermore, in this utility model, the use of terms such as "first" and "second" is for descriptive purposes only and does not specifically refer to any order or sequence, nor is it intended to limit the utility model. They are merely used to distinguish components or operations described with the same technical terms and should not be construed as indicating or implying their relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of various embodiments can be combined with each other, but only if they are feasible for those skilled in the art. If a combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0018] As shown in Figures 1 to 3, a protective structure for a vehicle-mounted mapping device comprises a chassis 1 and a body 2 mounted on the chassis 1. A mounting base 3 is fixedly installed at one end of the body 2 near the driver's cab. A lifting mechanism 5 is installed on the mounting base 3. A mapping device 6 is fixedly installed at the top of the lifting mechanism 5. An exit is provided on the top of the body 2 corresponding to the mapping device 6. A top cover 8 that can slide on the top of the body 2 is provided at the exit. An operating area is provided at the end of the body 2 away from the driver's cab.

[0019] Furthermore, a limit switch 4 is installed on the mounting base 3, and a limit switch 10 that cooperates with the top cover 8 is fixedly installed at the top of the body 2 away from the driver's cab. The limit switch 4, the limit switch 10, the lifting mechanism 5, and the drive mechanism 7 for sliding the top cover 8 are all connected to the control device.

[0020] Furthermore, a fixing plate 9 is arranged parallel to both sides of the outlet. The fixing plate 9 is provided with a front slide groove and a rear slide groove 91 with the same structure. The rear slide groove 91 is provided with a downward inclined groove 92 at the end near the cab. A pulley 81 is provided in the front slide groove and the rear slide groove 91 respectively. The pulley 81 is connected to the top cover 8.

[0021] Furthermore, a sealing strip is provided at the bottom of the top cover 8 where it contacts the outlet.

[0022] Furthermore, an inspection door is provided on the side wall of the compartment 2 corresponding to the location of the surveying device 6.

[0023] When the surveying device 6 needs to be raised, the top cover 8 moves to the right under the drive of the drive mechanism 7. When the right end of the top cover 8 contacts the limit switch 10, the top cover 8 stops moving, and the lifting mechanism 5 starts to rise until the surveying device 6 is raised outside the compartment 1.

[0024] When the surveying device 6 needs to be retracted, the lifting mechanism 5 descends. When the lifting mechanism 5 is fully retracted, it touches the limit switch 4, and the lifting mechanism 6 stops moving. The top cover 8 moves to the left under the drive of the drive mechanism 7 until it completely covers the exit.

[0025] Because the front and rear chutes 91 are provided with downward-sloping inclined grooves 92 at the end near the cab, when the top cover 8 moves to the inclined groove 91, it will move downward, making the top cover 8 contact the outlet more tightly. A sealing strip is provided at the contact point between the bottom of the top cover 8 and the outlet, which can effectively prevent foreign objects from entering the compartment 1 from the contact point between the top cover 8 and the outlet when the vehicle is moving, and effectively protect the surveying device 6.

[0026] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
