[0019] The millimeter wave security inspection device provided by the embodiments of the present application will be described in detail below in combination with the drawings, specific embodiments and application scenarios.

[0020] As shown in the drawings, Figs. 1-10 The millimeter wave security inspection device disclosed by the embodiments of the present application has the characteristics of fast scanning mode imaging speed, comprehensive detection, safety and reliability, good privacy protection effect, high detection precision, etc.

[0021] The millimeter wave security inspection device comprises a device main body 100 and at least two moving mechanisms 200. The device main body 100 is provided with a millimeter wave antenna array. Optionally, the device main body 100 can be a single door millimeter wave device (the millimeter wave antenna array is arranged in the door), can be a through-type millimeter wave device with two opposite doors, or can be a millimeter wave device with multiple scanning working surfaces. The embodiments of the present application do not make specific limitations in this regard.

[0022] Each moving mechanism 200 is arranged at the bottom of the device main body 100, and the moving mechanisms 200 are arranged in sequence and at intervals. Optionally, the moving mechanisms 200 are uniformly distributed in sequence along the circumference of the device main body 100, so that the force acting on the device main body 100 distributed on the moving mechanisms 200 is approximately equal.

[0023] Each moving mechanism 200 comprises a roller assembly 220, and the roller assembly 220 is movably connected with the device main body 100, that is, the roller assembly 220 can move relative to the device main body 100. In the case that the millimeter wave security inspection device is in a first state, the roller assembly 220 is used to contact with a device bearing surface (here, the device bearing surface can be the ground, vehicle chassis, etc.); in the case that the millimeter wave security inspection device is in a second state, the device main body 100 is used to contact with the device bearing surface.

[0024] In the embodiment of the present application, the mobile mechanism 200 is additionally arranged on the device main body 100 of the millimeter wave security inspection device. When the millimeter wave security inspection device needs to be moved, the roller assembly 220 is driven to move relative to the device main body 100 so as to be stretched out, at this time, the device main body 100 is lifted, the roller assembly 220 is in contact with the device bearing surface, thereby realizing the movement of the millimeter wave security inspection device. When the millimeter wave security inspection device needs to be fixed, the roller assembly 220 is reversely driven to move relative to the device main body 100 so as to be retracted, at this time, the device main body 100 is supported on the device bearing surface, the supporting area is large, and the stability of the millimeter wave security inspection device is good. Therefore, the embodiment of the present application can solve the problem that the current moving mode of the millimeter wave security inspection device is complicated.

[0025] Optionally, the roller assembly 220 can be directly driven to move relative to the device main body 100 by human; or in other optional embodiments, each mobile mechanism 200 further includes a driving member 230, the driving member 230 is arranged on the device main body 100, the driving member 230 is connected with the roller assembly 220, and the driving member 230 can drive the roller assembly 220 to move relative to the device main body 100 so as to make the roller assembly 220 contact with the device bearing surface or make the device main body 100 contact with the device bearing surface. In this scheme, the driving member 230 drives the roller assembly 220 to move relative to the device main body 100, which can save labor.

[0026] In a further optional embodiment, the roller assembly 220 and the driving member 230 can be directly arranged on the device body 100; or each movement mechanism 200 further comprises a base 210, the base 210 is connected with the device body 100, and the base 210 and the device body 100 can be detachably connected through bolts, screws or the like, or can be fixedly connected through welding or the like, and the present application embodiment does not make a specific limitation thereon. The base 210 is provided with an opening, at least part of the roller assembly 220 is arranged in the accommodating space of the base 210, the roller assembly 220 is movably connected with the device body 100 through the base 210, that is, the roller assembly 220 can move relative to the base 210, the driving member 230 is arranged on the base 210, the driving member 230 is connected with the device body 100 through the base 210, the driving member 230 can drive the roller assembly 220 to move up and down relative to the base 210, so that at least part of the roller assembly 220 extends out of the accommodating space through the opening of the base 210 and contacts with the device bearing surface, or the roller assembly 220 is retracted into the accommodating space, and the device body 100 contacts with the device bearing surface. It should be noted that the up and down here specifically refers to that when the millimeter wave security inspection device is placed on the device bearing surface, the roller assembly 220 moves along the height direction of the device body 100 (i.e. the extension direction from the bottom to the top of the device body 100). This scheme concentrates the roller assembly 220 and the driving member 230 on the base 210 to form a modular structure, which facilitates the disassembly and maintenance of the movement mechanism 200; and can reduce the number of connecting holes on the device body 100, thereby ensuring the structural strength of the device body 100.

[0027] Optionally, the roller assembly 220 and the inner surface of the base 210 can be gap-fitted; or in other optional embodiments, the opposite end surfaces of the roller assembly 220 are provided with sliding protrusions 221 in the extension direction of the central shaft of the roller assembly 220, and the opposite side walls of the base 210 are provided with sliding grooves 211, which optionally extend to the outer surface of the base 210 to facilitate the opening of the sliding grooves 211. The sliding protrusions 221 and the sliding grooves 211 are slidingly fitted, the first end of the sliding groove 211 is located lower than the second end of the sliding groove 211, when the sliding protrusion 221 is located at the first end of the sliding groove 211, at least part of the roller assembly 220 extends out of the containing space through the opening of the base 210; when the sliding protrusion 221 is located at the second end of the sliding groove 211, the roller assembly 220 is retracted into the containing space of the base 210. When the driving member 230 drives the roller assembly 220 to lift, the sliding protrusion 221 of the roller assembly 220 and the sliding groove 211 of the base 210 are slidingly fitted to ensure that the roller assembly 220 lifts in the predetermined direction, avoiding the inclination of the roller assembly 220 during lifting, thereby improving the lifting stability of the roller assembly 220; and the connection relationship between the roller assembly 220 and the base 210 is established, which is conducive to improving the stability of the roller assembly 220 during the movement of the millimeter wave security inspection equipment.

[0028] In optional embodiments, the driving member 230 can be a motor, a pneumatic cylinder, a hydraulic cylinder, etc.; or the driving member 230 includes a pull rod 231, the first end of the pull rod 231 is movably connected with the base 210 and the roller assembly 220, the pull rod 231 can rotate relative to the base 210 to drive the roller assembly 220 to lift relative to the base 210, when it is needed to move the millimeter wave security inspection equipment, the pull rod 231 is manually driven to rotate relative to the base 210 to make the pull rod 231 drive the roller assembly 220 to descend relative to the base 210; when it is needed to support the millimeter wave security inspection equipment on the equipment bearing surface, the pull rod 231 is manually driven to reversely rotate relative to the base 210 to make the pull rod 231 drive the roller assembly 220 to ascend relative to the base 210. This scheme sets the driving member 230 as the pull rod 231, and drives the roller assembly 220 to lift through the pull rod 231, which can save the power consumption of the millimeter wave security inspection equipment. Of course, compared with directly driving the roller assembly 220 to move by human, the present case drives the roller assembly 220 to lift by pushing the pull rod 231, which is still more labor-saving.

[0029] Optionally, the rotation center axis of the pull rod 231 is parallel to the height direction of the device body 100, when the pull rod 231 rotates in the horizontal plane, at this time, the pull rod 231 occupies a smaller space in the height direction of the device body 100, which can avoid the interference between the pull rod 231 and the device body 100. Of course, the rotation center axis of the pull rod 231 can also be perpendicular to the height direction of the device body 100, at this time, the pull rod 231 rotates in the vertical plane.

[0030] Optionally, the sliding groove 211 can be an inclined straight line structure; or in another optional embodiment, the sliding groove 211 includes a first limiting section 211a, a guide section 211b and a second limiting section 211c connected in sequence, the first limiting section 211a is located at the first end of the sliding groove 211, the second limiting section 211c is located at the second end of the sliding groove 211, and the guide section 211b is inclinedly arranged to make the first limiting section 211a and the second limiting section 211c have a certain distance in the horizontal direction, at this time, in the process of the sliding cooperation between the roller assembly 220 and the sliding groove 211, the roller assembly 220 moves in the horizontal direction while lifting, that is, the movement path of the roller assembly 220 is arranged obliquely.

[0031] When the sliding convex part 221 is located at the first end of the sliding groove 211, the sliding convex part 221 is limitedly matched with the first limiting section 211a; when the sliding convex part 221 is located at the second end of the sliding groove 211, the sliding convex part 221 is limitedly matched with the second limiting section 211c. Specifically, when the pull rod 231 drives the roller assembly 220 to descend, the sliding convex part 221 of the roller assembly 220 is slidably matched with the sliding groove 211 of the base 210, and when the sliding convex part 221 slides to be limitedly matched with the first limiting section 211a, the pull rod 231 stops working, at this time, part of the roller assembly 220 protrudes out of the containing space of the base 210 and contacts with the device bearing surface, which can avoid the relative sliding between the base 210 and the sliding convex part 221 caused by the gravity of the device body 100; when the pull rod 231 drives the roller assembly 220 to ascend, the sliding convex part 221 of the roller assembly 220 is slidably matched with the sliding groove 211 of the base 210, and when the sliding convex part 221 slides to be limitedly matched with the second limiting section 211c, the pull rod 231 stops working, at this time, the roller assembly 220 is retracted into the containing space, which can avoid the relative sliding between the roller assembly 220 and the sliding groove 211 caused by the gravity of the roller assembly 220.

[0032] The above scheme sets the first limiting section 211a and the second limiting section 211c, when the millimeter wave security inspection device is in a moving state, the sliding convex part 221 is limitedly matched with the first limiting section 211a, thereby improving the stability of the device movement; when the millimeter wave security inspection device is in a stationary state, the sliding convex part 221 is limitedly matched with the second limiting section 211c, thereby improving the stability of the device stationary.

[0033] In another optional embodiment, the first end of the pull rod 231 is rotationally connected with the base 210, and the driving member 230 further comprises a first connecting column 232, the first end of the first connecting column 232 is connected with the first end of the pull rod 231. Optionally, a protrusion can be arranged on the roller assembly 220, and the first end of the pull rod 231 is provided with an arc-shaped hole, the protrusion is matched with the arc-shaped hole, when the pull rod 231 rotates in the water surface, the pull rod 231 drives the roller assembly 220 to move in the horizontal direction while lifting; or, the support 222 of the roller assembly 220 is provided with a strip-shaped hole 222a, the strip-shaped hole 222a is a linear structure, the second end of the first connecting column 232 extends to the side of the support 222 away from the pull rod 231 through the strip-shaped hole 222a, the first connecting column 232 is matched with the inner wall of the strip-shaped hole 222a, the pull rod 231 can drive the roller assembly 220 to lift and move in the horizontal direction through the first connecting column 232. Optionally, the second end of the pull rod 231 is provided with a handle 231c to facilitate the staff to hold.

[0034] Specifically, the pull rod 231 rotates in the horizontal plane, the pull rod 231 drives the first connecting column 232 to rotate together, a certain pulling force is generated between the first connecting column 232 and the inner wall of the strip-shaped hole 222a, so as to pull the support 222 to move out of the containing space, so that the roller assembly 220 descends; similarly, the pull rod 231 reversely rotates in the horizontal plane, the pull rod 231 drives the first connecting column 232 to rotate together, a certain pushing force is generated between the first connecting column 232 and the inner wall of the strip-shaped hole 222a, so as to push the support 222 to move into the containing space, so that the roller assembly 220 rises. The driving member 230 and the roller assembly 220 in this scheme adopt the above connection mode, which can ensure the structural strength of the pull rod 231, and the pull rod 231 is not easy to break when the pull rod 231 is artificially driven; and the strip-shaped hole 222a is easy to manufacture.

[0035] Optionally, the base 210 is provided with an avoiding opening 212 for avoiding the first connecting column 232, the avoiding opening 212 is located at the top surface of the containing space, so as to ensure that the first connecting column 232 can flexibly rotate in the horizontal plane together with the pull rod 231.

[0036] Optionally, the avoiding opening 212 is in communication with the opening of the base 210 for avoiding the moving mechanism 200, that is, the opening of the base 210 for avoiding the moving mechanism 200 is located at the bottom wall and the side wall of the base 210, at least part of the roller assembly 220 protrudes from the bottom surface of the base 210 and extends out of the side wall of the base 210 during the lifting of the roller assembly 220.

[0037] Optionally, the second end of the first connecting column 232 is provided with a limiting flange, the limiting flange is located on the side of the support 222 away from the pull rod 231, when the sliding convex part 221 is limited and matched with the first limiting section 211a, the limiting flange can be limited and matched with the support 222, so as to avoid that the first connecting column 232 is disengaged from the strip-shaped hole 222a.

[0038] In another optional embodiment, the roller assembly 220 comprises a support 222, a roller 223 and a connecting shaft 224, the roller 223 is rotatably sleeved on the connecting shaft 224, the opposite two side walls of the support 222 are provided with connecting holes, and the support 222 is sleeved on the connecting shaft 224 through the connecting holes, that is, the support 222 is relatively fixed with the connecting shaft 224, and optionally, the opposite two end faces of the support 222 can be respectively provided with the sliding convex part 221; or in another optional embodiment, the opposite first end and second end of the connecting shaft 224 pass through the connecting holes and are slidably matched with the sliding groove 211, the first end and the second end of the connecting shaft 224 respectively form the sliding convex part 221 arranged on the opposite two end faces of the roller assembly 220, and the first end of the pull rod 231 is movably connected with the support 222. The connecting shaft 224 in this scheme has a dual-purpose effect, in the process that the roller assembly 220 is lifted relative to the base 210, the connecting shaft 224 is slidably matched with the sliding groove 211 of the base 210, so as to drive the support 222 and the roller 223 to lift together; when at least part of the roller assembly 220 extends out of the opening of the base 210 to the containing space, the roller 223 is in contact with the equipment bearing surface, and the roller 223 can rotate around the connecting shaft 224; in addition, this scheme utilizes the first end and the second end of the connecting shaft 224 to respectively form the sliding convex part 221 arranged on the opposite two end faces of the roller assembly 220, so that it is not necessary to additionally provide the sliding convex part 221 on the opposite two end faces of the support 222, which is conducive to simplifying the structure of the support 222.

[0039] In an optional embodiment, the first end of the pull rod 231 is rotatably connected with the edge of the base 210, in the case that at least part of the roller assembly 220 extends out of the containing space, the pull rod 231 is in an unfolded state, that is, the pull rod 231 extends out of the equipment main body 100; in the case that the roller assembly 220 is retracted into the containing space of the base 210, the pull rod 231 is in a retracted state, that is, the pull rod 231 is retracted into the equipment main body 100, and at least part of the pull rod 231 is stacked on the base 210.

[0040] When the first end of the pull rod 231 is connected with the edge of the base 210, the length of the pull rod 231 can be set longer at this time to increase the force arm of the pull rod 231, thereby facilitating the saving of driving force when the pull rod 231 is artificially driven; and when at least part of the operating rod 231 is superposed on the base 210, the pull rod 231 occupies less space in the length direction of the roller assembly 220, and even does not need to occupy additional space.
