Technical Field
[0001] This utility model relates to the field of radar vehicle technology, specifically a movable spatial expansion structure. Background Technology
[0002] A radar vehicle is a multi-functional outdoor radar survey vehicle. As a functional outdoor detection vehicle, it is equipped with a variety of radar detection devices, which makes it significantly different from ordinary vehicles. Because existing radar vehicles need to be equipped with a variety of detection devices, the rear of the vehicle is generally a box structure. This improves the vehicle's driving stability and allows for the loading of various radar detection devices in the cargo box.
[0003] With the continuous upgrading of radar detection equipment, radar vehicles will carry various equipment for use. However, the current box-type structure of radar vehicles is relatively simple. Some detection equipment needs to be moved out of the radar vehicle and set up outside when in use, which will have a certain impact on the safety of the detection equipment. At the same time, moving the equipment back and forth between the inside and outside of the vehicle will also affect the efficiency of radar detection. Therefore, the fixed cargo box can no longer meet the needs of the placement and use of various equipment. There is an urgent need for a movable space expansion structure to solve the problem of limited space in the current fixed cargo box. Utility Model Content

The top of the first fixing seat is provided with a placement groove, and a limiting rod is rotatably installed on the inner side of the placement groove. The top of the limiting seat is provided with a limiting groove, and the limiting rod is engaged with the inner side of the limiting groove.
[0010] As a preferred technical solution of this utility model, the surface of the limiting seat is slidably connected to a plug rod, and the surface of the limiting rod is provided with a plug hole that matches the size and position of the plug rod.

[0025] Please see Figure 1-7In this embodiment: a movable space expansion structure includes a chassis 1, a cargo box body 2 fixedly mounted on the top of the chassis 1, a rear cargo box 3 and a front end 4 respectively mounted on the top of the chassis 1 and on the left and right sides of the cargo box body 2, a wheel assembly 5 mounted on the bottom of the chassis 1, a fixed frame 23 fixedly inserted into the middle of the cargo box body 2, and through-hole receiving grooves 21 respectively opened on the front and back of the cargo box body 2. An expansion body 6 is slidably mounted on the inner side of the receiving groove 21, an open groove 63 is opened on the side of the expansion body 6, a door 61 is hingedly mounted on the inner side of the open groove 63, and a handle 64 is fixedly mounted on the surface of the door 61. The two extended compartments 6 are connected on opposite sides and are both open designs. By setting up the receiving slot 21 and the extended compartments 6, the user can place the detection equipment inside the extended compartments 6. When the radar vehicle is parked, the extended compartments 6 can be pulled out from the receiving slot 21, and then the compartment door 61 can be opened. In this way, the detection equipment can be directly pulled out of the cargo body 2. The user can stand outside the open slot 63 to install and use the detection equipment. After the extended compartments 6 are pulled out, the receiving slot 21 is empty and can still be used to place other equipment. This expands the usable space inside the cargo body 2 and facilitates the use of the detection equipment, further improving the convenience of parking operations for the radar vehicle.
[0026] In a preferred embodiment, symmetrically distributed sliding grooves 22 are provided at the bottom and top of the inner side of the receiving groove 21, and symmetrically distributed sliding blocks 62 are fixedly installed at the top and bottom of the expansion compartment 6, with the sliding blocks 62 slidably engaging with the inner side of the sliding grooves 22. Through the cooperation and connection between the sliding grooves 22 and the sliding blocks 62, the smoothness and safety of the expansion compartment 6 when it is pulled out can be improved, and the expansion compartment 6 can be limited to improve its stability.
[0027] In a preferred embodiment, one end of a hydraulic telescopic rod 67 is rotatably mounted on the side of the door 61 and inside the extended compartment 6, and the other end of the hydraulic telescopic rod 67 is rotatably mounted on the bottom of the inner side of the extended compartment 6; the door 61 is supported by the hydraulic telescopic rod 67, thereby improving the stability of the door 61 when opening.

The top of the limiting seat 8 is provided with a limiting groove 81, and the limiting rod 72 is engaged with the inner side of the limiting groove 81. When the extended compartment 6 is not in use, the limiting rod 72 can be rotated to engage with the limiting groove 81, thereby limiting the extended compartment 6 and preventing it from shaking during the operation of the radar vehicle, thus further improving the stability of the extended compartment 6.
[0031] In a preferred embodiment, a plug rod 82 is slidably installed on the surface of the limiting seat 8. The surface of the limiting rod 72 has a plug hole that matches the size and position of the plug rod 82. After the limiting rod 72 is snapped into the limiting groove 81, the plug rod 82 is then inserted into the plug hole. This can fix the limiting rod 72 and prevent the limiting rod 72 from coming off the limiting groove 81 during the radar vehicle's operation.
[0032] In a preferred embodiment, symmetrically distributed second fixing seats 9 are fixedly installed on the surface of the extended body 6 and on both sides of the door 61. An extension rod 91 is slidably inserted into the side of the second fixing seat 9 closest to the door 61, and a sliding rod 92 is slidably inserted into the side of the second fixing seat 9 away from the door 61. The sliding rod 92 is fixedly connected to the extension rod 91. Pulling the sliding rod 92 can drive the extension rod 91 to move, so that the extension rod 91 is in contact with or away from the side of the door 61, thus achieving further limitation of the door 61.
